Sand DryerBrief Description: Sand Dryeris widely used in construction materials, ore dressing, metallurgy, chemical industry, cement industry, etc. Sand Dryer are used for drying all kinds of sand such as river sand, yellow sand, silica sand, quartz sand, pomegranate sand, etc. Sand Dryer mainly consist of rotary drum, carrier roller, lifting boards, hot air furnace, electric control box, etc. Sand Dryer Features: New type rotary drum dryer, the flights structure in the cylinder of sand dryer is more advanced ; Inner temperature is 450-700, discharging temperature <= 60 , can send into storage room directly, and no need cool device; Made of wear resistant manganese plate, 3 to 4 times more hardwearing than ordinary steel plate ; 1/3 of the traditional drum dryer's coal consumption, electricity power saving 40%,standard coal consumption per tondried sand< 16 kg. Wet Sand Input Dried Sand Output Sand Dryer Workflow: Belt Conveyor or bucket elevator transports the wet sand into the hopper which is on the top of sand dryer. Hot air furnace supply the hot air for the sand dryer. Inside the sand dryer's cylinder, there are many flights, and these flights mix the wet sand and hot air sufficiently. The humidity in the wet sand is heated and evaporated into water vapour. At the end of the sand drying plant, there is one high pressure draft fan. Under the function of draft fan, the water vapour goes out of sand dryer in time. During the sand drying process, there is some dust mixed with the water vapour. In the cyclone separator, the dust is separated from the water vapour, and falls down. The dried sand goes out of the sand dryer machine from the outlet as product. Finally we can use one belt conveyor or bucket elevator to send the dry sand into silo or trucks. Fuel for Sand Dryer: Fuel for the heat source can be wood pellets, waste wood, coal, diesel, natural gas, biomass fuel, etc. The users can choose the most suitable fuel according the actual situation such as fuel available, fuel cost, local environment laws, etc. Partial Technical Data of Sand Dryer Machine: Model Processing Capacity Input Moisture Output Moisture MainMotor forSandDryer Coal CalorificValue Feedinlet Temperature 1.5X14M 10-12 17-23% <10% 15 >5500KCAL/KG 70050 1.8X14M 15-18 17-23% <10% 18.5 >5500KCAL/KG 70050 2.0X16M 20-25 17-23% <10% 18.5 >5500KCAL/KG 70050 2.2X18M 25-30 17-23% <10% 22 >5500KCAL/KG 70050 Notice: Any change ofSandDryertechnical data shall not be advised additionally.

If you need a dryer, you have surely already waded through the plethora of options on the market today. How will you ever choose the best one for your application? The purpose of this article is to inform you about rotary drum dryers, because they can be the most affordable and economic choice when considering a new or used dryer. Plus, they are the most versatile of all dryer designs today.
Rotary drum dryers can be chosen for projects as large as evaporating half a million tons of water to as small as evaporating several tons of water. They come in all sizes to accommodate many products, quantities, and moisture content ranges. Although, they can be larger, 18 diameter drums seem to be the largest practical for manufacture, transport, and installation. Depending on length, an 18 drum could evaporate 120,000-lbs/hr of water. Say the product to be dried starts at 50% moisture content wet basis (mcwb), this drum could handle 120-ton/hour or more. At 8,400 operating hours per year, youre looking at a million tons of product infeed going through every year, or about half a million tons per year of final product.
An 18 dryer drum is not the only option. Rotary dryer drums as small as 4 diameter can evaporate anywhere from 200 500-lbs/hr. Rotary drums much smaller than this have efficiency losses so an alternate drying system may be more beneficial. Using the same example above, with a product at 50% mcwb, a small rotary drum dryer can take care of 400 1,000-lb/hr of product, or 1,680 4,200-ton/year infeed and approximately half that of product out. Obviously, these numbers depend on a variety of variables not the least of which is the moisture content of the infeed and the desired moisture content of the final product.
Rotary drum dryers can be designed to withstand extremely high temperatures and/or corrosive materials. A basic carbon steel drum is designed to withstand inlet temperatures from 1,000F 1,100F. Of course rotary drum dryers can be designed to handle different inlet temperatures. Stainless steel can be used in place of carbon steel if the product is known to be corrosive. Other materials can be substituted as well depending on the nature of the product to be dried.
Rotary drum flighting is the primary material handling mechanism in a drum. Flighting can be designed to accommodate different flow characteristics of the materials to be dried. Some materials clump and potentially form balls which need to be broken up, while others flow like water and need to be slowed down. Other pieces might be long and stringing and can easily get trapped. Different flighting designs can solve these, and other, problems.
With so many specialized dryers available today, it seems that every single product has a different dryer designed specifically for it. What happens if you quit making a particular product that had a specialized dryer? Can the dryer be modified to dry something else? If it is a rotary drum dryer the answer is yes, another wonderful feature of a rotary drum dryer is that the flighting system can be changed to repurpose a used or existing dryer. A flighting designer, oddly enough they do exist, can look at the flow characteristics of the material in question and determine what kind of flights are necessary, thereby converting the dryer to a new purpose at a fraction of the cost of buying a new dryer.
Rotary drum dryers can dry many different types of products. Not only are they great for uniform solid particles, but they are the best solution for non-uniform solid particles. The number one factor in deciding a dryer is whether the material handling of the dryer matches what the product needs.
Products that have non-uniform particle sizes are perfect candidates for a rotary drum dryer, like the wood in the picture above. However, the flighting system would be different for the sample on the left than for the sample on the right. It is important to know the characteristics of the infeed product to choose the best flighting design.
A rotary drum dryers greatest asset is its ability to accommodate a product that has multiple size particles and moisture contents by utilizing the right flighting package. As seen in the picture above the wood is in a variety of shapes and sizes. The larger, heavy particles will be carried less distance by the drying gases than the smaller, lighter particles. This means that the smaller particles can exit the dryer before they become over-dry and the larger particles can remain in the drum until they have dried a sufficient amount. The flights can be designed to keep the larger pieces in the drum longer and allow the smaller pieces to flow more quickly. The right flighting package can help achieve uniform product quality and can also lead to reduced emissions.
Unfortunately, rotary drum dryers seem to have fallen into a niche market. Dryer manufacturers and purchasers have been shying away from rotary dryers recently because of perceived reliability, quality and versatility issues.
One of the perceived issues is lack of reliability. Drum shell, headplate, or tire flexing can lead to premature failure. Rotary drum dryers get a bad rap due to some drums not being designed and built correctly or drums being repurposed without upgrading them for the new product or application. Without proper internal and external support, the drum has a tendency to flex while rotating in some instances causing horrible shaking and vibrating. Some drums have been measured to continually be wider than tall, flexing every time it rotates. Imagine if you will, a water balloon rolling down the sidewalk. When steel flexes to that degree eight times per minute (based on 4-RPM), it does not take long before the thing breaks. Given the right design, construction materials, and fabrication techniques a well-built rotary drum dryer should last for 20+ years without any major structural issues, such as cracks in the shell or headplates.
Another perceived issue is lack of versatility. The importance and flexibility of different flighting packages is often misunderstood in the industry. Many of the rotary drum dryers that are available today only have the option of one type of flighting package. To get the most out of your rotary drum find a manufacture that offers flighting packages for your applications and products.
Another challenge facing rotary drum dryers is a reputation of poor product quality and excessive emissions. This can be overcome in a few ways, two of which are discussed here. The first way we already discussed above by utilizing the right flighting package for your product. The next way is through the use of Exhaust Gas Recycle, EGR, (also known as Flue Gas Recycle, FGR) the product can be protected from hot, dry, drying gases by recycling water vapor back through the system and increasing the wet bulb temperature. The higher wet bulb temperature allows the particle internals to heat at the same rate as the externals, thereby allowing an even evaporation rate. If the wet bulb temperature is low because the system does not have enough moisture, the outside of the particle can flash dry and act as an insulator to the inside, not allowing the moisture to migrate to the surface. The particle can reach the end of the drum with an over-dried or, worse yet, charred outside and wet inside. This is kind of like putting a burger on the grill when the coals are too hot. Over-drying or charring the outside gives off volatile organic compounds (VOCs) which will cause a haze and/or bad smell outside the plant if a back-end cleanup system has not been utilized. Not over-drying the outside means less potential VOCs which means lower emissions. Another added benefit of EGR and the right flighting package for your product is the potential to lower the inlet temperature. High inlet temperatures cause most of the over-drying, so lowering the inlet temperature will also reduce the potential for VOC emissions.
In conclusion, rotary drum dryers are the work horse of the drying industry because of their longevity, capacity and ability to be adapted to new purposes. Do not overlook a rotary drum dryer when trying to decide how to improve or expand your drying equipment as you can see how easy it is to overcome these perceived problems.
Since 1948 more than 500 dryers have been installed with the MPS (multi-pass-system) system. Traditionally the focus was on the agricultural area (as an example alfalfa (lucerne) is used as horse feed), but has been changed more to the alternative fuel area now.
In the alternative fuel market biomass (wood residue) is dried for the production of white pellets, brown pellets or black pellets. In each of these processes drum dryers can decrease the moisture to the desired level for downstream process steps. ANDRITZ Vandenbroek rotary drum dryers are available for evaporation capacities from 3-35 tons water per hour.
Waste is considered as valuable raw material for the production of energy. Municipal Solid Waste (MSW) can be divided in the organic fraction (wood waste, wood trimming, etc.) and Refused Derived Fuel (RDF, i.e. plastics, paper, etc.). This RDF fraction (normally moisture content of 35-40%) can be enhanced to Solid Recovered Fuel (SRF) by reducing the moisture content in the drum dryer.
For evaporating moisture from concentrates or other products from plant operations, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption.Whenever possible to apply heat direct to the material to be dried, Rotary Dryers of the Direct Heating Design are used. If it is not possible to apply heat direct to the material to be dried, Rotary Dryers of the Indirect Heating Design can be furnished so that the heated gases will not come in direct contact with the material.
Rotary Dryer is a simple, inexpensive unit for reducing the moisture content of flotation concentrates, as well as chemical and industrial products. Frequently the saving of shipping weight so effected will pay for the dryer in a few months. Difficulties from freezing while in transit are also eliminated. Many industrial projects are now using Dryers for control and production purposes on many materials.
Three main types of Rotary Dryers can be supplied. The direct heat unit is used when it is permissible for the drying gases to come in direct contact with the material being dried. Partition plates increase the heating surface. Drying may be by hot air or exhaust gases from other operations. If this drying gas has a deleterious effect on the product, then an indirect type of dryer can be supplied. A further derivation is the Tedrow Steam Dryer.
Of the different types of dryers that there are the most common is the ROTARY DRUM DRYER/Kiln, This type of drier is common not only in the mining industry but you will find them in fertilizer plants, Cement plants, and peat hogs to name but a few.
The theories behind these machines are very simple, heat an air space up, and then tumble the material to be dried through this space until it is dried. All though it sounds simple there are problems that have to be solved before the required results are met. But first, so you know what we are talking about lets go through the design of a drier.
First is the KILN, this provides the heat, The BURNER is inside this portion. The fuel for the burner is usually diesel although heavy crude oil could be used in some cases. To be able to generate enough heat to dry the concentrate air must be added by way of a BLOWER. In front of the kiln is the point that the wet concentrate enters the drier. It is put into the revolving SHELL. The shell is on a slight incline. As the Concentrate is tumbled through the hot air mass of the drier it travels down this incline to the exit of the drier.
At this exit point the concentrate is either deposited straight into a storage area or taken to the storage area by a conveyor. It is also at this point that there is an EXHAUST HOOD. This provides a controlled escape passage for the fumes and water vapor that is generated by the concentrate drying. This is a very important function and the operator will have to be sure that it is open at all times. If it should become blocked the water vapor will not be able to escape. The concentrate will become wet and sticky which will result in the discharge plugging. The wet sticky concentrate will also lower efficiency level of the drier for an extended period of time. This happens because inside the drier shell are what are termed FLIGHTS these are flat pieces of metal that are bolted onto the shell.
They are there to lift the concentrate up to the top of the shells rotation and drop the concentrate through the hot air. If the water vapor isnt taken away, the concentrate becomes sticky from reabsorbing the water. This sticky concentrate will fill the spaces between the flights.
The concentrate will not be lifted and dropped through the hot air. This results in a long term condition of poor performance even after the initial problem has been cured. These flights will remain buried in concentrate. This removal of the water vapor is one of the functions of the blower. It assists the natural process of air movement as the hot air mass expands. To prevent the buildup of concentrate on the flights there are often CHAINS attached to them. As the drier revolves the chains slap the flights preventing concentrate from building up on dryers walls.
The drier shell is rotated separately from the stationary kiln section. To achieve the rotation a BULL GEAR is attached around the shell section. There are also two flat rings attached to the shell. These provide surfaces for support rollers to roll on. There is another problem that the inclined shell has, the incline causes the shell to want to slide in the direction of the incline. To prevent this additional rollers are attached to the last set of rollers.
When it comes to buying an industrial dryer, people are often faced with the decision to choose between a rotary dryer, and a fluid bed dryer. Historically, rotary dryers have been used for more industrial applications, such as minerals, fertilizers, and aggregates, while fluid bed dryers have been used more in the pharmaceutical, specialty chemical, and food industries. Despite some industry preferences, the drying capabilities of these two industrial dryers has allowed for a significant amount of overlap in applications, and subsequently, confusion for what is ultimately the best choice when comparing the two.
Though the choice between a rotary and fluid bed dryer can be material or industry specific, ultimately, each dryer has its own advantages and disadvantages. With comparable capital costs, the decision often comes down to what will best suit the processing conditions, with a few considerations to keep in mind.
Rotary dryers have been called the workhorse of the industrial drying industry, due to their heavy-duty construction, their high-capacity capabilities, and most of all, their ability to accept a significant variance in feedstock. Because of this, rotary dryers are better suited for heavy-duty materials where a lot of variety in feedstock is a given, such as in the case of various minerals. Rotary dryers are known for their ability to take what is given, big or small, wet or dry, lumpy or uniform, and yield a quality product.
Conversely, fluid bed dryers have a very tight window when it comes to variability in feedstock, requiring as much uniformity in particle size distribution and moisture content as possible. Where a rotary dryer will just keep running with little to no process upset, variability in feedstock with a fluid bed dryer has the potential to leave an operation at a standstill. Feedstock with lumps or inconsistencies in moisture content can cause serious problems when processed in a fluid bed dryer.
Additionally, rotary dryers are better suited for heavy-duty processing loads, such as those found in the mining industry. Because it takes significant energy to fluidize large or heavy materials, it is not practical to process these types of materials in a fluid bed dryer. Fluid bed dryers are best reserved for applications processing lighter-duty materials.
Materials that must not suffer degradation are better served in a fluid bed dryer. Rotary dryers often result in some, albeit little, degradation and attrition to material, because of the fact that the cascading action happening in the dryer. This is not an issue with all materials, but can be an issue with some. Rotary dryers do offer the advantage of polishing granules, however; because of the rolling action on the bed of material, granules are further rounded, or polished, and loose edges are knocked off.
Rotary dryers require significantly less supervision than their fluid bed counterparts. Rotary dryers are largely unaffected by fluctuations in feedstock and other processing conditions such as reduced feed. They offer a consistently reliable solution in settings where inconsistencies in feedstock and instabilities in processing are to be expected.
Fluid bed dryers are much less suited for these types of situations, requiring a consistent processing environment. Variations in operational parameters can cause major problems when working with a fluid bed dryer.
The choice between a rotary dryer or fluid bed dryer is also a matter of energy. Fluid bed dryers work by fluidizing the material, which requires a high magnitude of air. Additionally, because it takes a certain amount of energy to fluidize a material, energy is not reduced when running at lower capacities. As mentioned, because material is fluidized, it is not always practical to run high volume, heavy materials through a fluid bed dryer, because of the extra energy required to fluidize the material.
Fluid bed dryers are considered to be more thermally efficient than rotary dryers, however. This is because the heat transfer is maximized due to the fluidization effect; each granule is surrounded by the drying air.
In many industrial processes, rotary dryers are relied upon for high capacity, consistent drying of bulk solids and for good reason. They offer innumerable benefits, both to the process and the product.
One of the most prominent components of a rotary dryer is a large, rotating cylinder called the drum shell. Drying air or process gas flows through the drum in co-current or counter-current modes. In co-current mode, material travels in the same direction as the process gas. In counter-current mode, material travels in the opposite direction of the process gas. Regardless of the direction of travel, the drying air comes in direct contact with the material being dried.
Rotary dryers are used both for post-drying and pre-conditioning. Post-drying is a method of reducing the moisture content of a final product. Pre-conditioning is a method of drying a material prior to subsequent processing.
For instance, by designing around a materials unique characteristics and the overall goals of the process, rotary dryers can attain optimum processing efficiency. Various material characteristics affect how the material behaves during the drying process. The characteristics of the material to be dried also influence dryer design to ensure the thermal processing satisfies the production goals. When designing a rotary dryer, consider key material characteristics such as:
In addition, site-specific factors can affect how a dryer performs and should be taken into account during the design phase. Typical factors include the humidity level, the elevation and ambient temperatures.
A multitude of components can be customized to suit most processing needs. Factors such as airflow configuration, flight design and pattern, percent fill, retention time and size will affect how the dryer performs to meet its intended goal. Additional customizations such as knocking systems, seal options and materials of construction can be combined to create an efficient drying solution tailored to your unique processing requirements.
When used to dry pellets or granules, rotary dryers offer an advantage over other drying mediums. The tumbling action on the bed of material further rounds and polishes the granules, knocking off any loose edges and creating a more refined product.
Rotary dryers are robust and offer a heavy-duty design. While they can be used to process fines, they are particularly adept at processing heavier materials such as those found in the mining industry. For this reason, materials commonly processed in a rotary dryer include potash, phosphates, gypsum, limestone, minerals and ores.
In addition to their heavy-duty processing capabilities, rotary dryers are perhaps most valued for their ability to churn out a consistent-quality product despite inconsistencies in the feedstock or process. Flights within the rotating drum lift and cascade material as it tumbles through the drum, preventing material clumps and promoting an evenly dried final product. They are able to take what is given lumpy or uniform, wet or dry and produce a quality product.
Rotary dryers are particularly valuable in settings where variance in the feedstock is a given such as when processing minerals. While a change in moisture or particle size distribution might leave a fluid bed drying operation at a standstill, a rotary dryer will continue to put out a fairly consistent product. This is also true of processing environments where upsets are likely such as power outages or lapses in fuel availability.
While rotary dryers do occupy a larger footprint than some other dryer types, this also means they offer significantly higher capacities. Rotary dryers can offer capacities ranging from as little as 1 ton per hour to in excess of 200 tons per hour. Continuous, high capacity processing is a necessity in many processing environments.
Rotary dryers typically require less energy than some other drying alternatives such as a fluid bed dryer. In addition, they offer the opportunity to save on energy costs when running at reduced capacities. For example, fluid bed dryers require a certain amount of energy, even when running at decreased capacities, because it takes a set amount of energy to fluidize a material. With a rotary dryer, however, energy consumption is reduced without process upset when running at lower capacities.
Heat transfer efficiency is increased with a rotary dryer through the use of lifting flights. The flights pick up the material and drop it through the airstream, creating a curtain of material as the drum rotates. Exposing the material to the airflow improves drying and moisture leveling.
Rotary dryers offer fairly hands-off operation. While a rotary dryer does need to be monitored, there are few things that can cause a process upset with a rotary dryer. There are also minimal variables to be adjusted, allowing for ease of operation.
Most rotary dryers are of the direct-fired type, meaning the material and drying air are in direct contact with each other. However, when ultra-fine materials must be processed, or the material to be processed must not come into contact with the drying air, an indirect-fired rotary dryer offers an effective processing solution. With indirectly heated rotary dryers, the drum is heated externally, and the material is dried through contact with the shell of the drum. This avoids any contact between the drying air and material. An indirect dryer is especially beneficial when entrainment of fine material is a concern. In conclusion, rotary dryers are the backbone of many modern industrial processes, helping to reduce the moisture content of final products and prepare material for additional processing. They offer a number of advantages for both the end product and the process itself. While rotary dryers are available in standardized models, a dryer tailored to the unique characteristics of the material to be processed will produce the most efficient and reliable results.

The Vulcan Drying Systems Hemp Drying System is custom-designed and manufactured to improve a customer's individual drying needs. These drying systems consist of a correctly sized drum and a burner mounted in a concurrent configuration. Vulcan Drying Systems Hemp Drying Systems are designed specifically to dry up to 10 tons per hour of hemp with an output moisture content between 10-12%.
Chopped hemp is fed into the rotary dryer by a feed conveyor. The dryer dries at low temperature by mounting a burner to a long combustion chamber to prevent direct contact with the burner flame. The burner flame is also cooled by a manifold of forced ambient air that passes through the combustion chamber as well. After passing through the dryer, the dried product is discharged to a transfer conveyor for further sorting, separation and processing. The vapor from the process is pulled through a large negative pressure chamber at the exit of the dryer to allow additional product drop out. Finally, the vapor is pulled through a cyclone or a baghouse to eliminate further airborne particulates.
The workhorse of the Vulcan Drying Systems Hemp Dryer is the heavy-duty, low-temp, direct-heating rotary drum dryer. The low-temp dryer is extremely energy-efficient and can be configured to utilize a variety of fuels to perform the drying process. Our single-pass system is a simple, low-cost method of producing a marketable product from biomass material. Low temperature is maintained by mounting a burner to a long refractory-lined chamber.

Hemp is created through the agricultural process of growing and harvesting hemp plants. Hemp is an organic product and causes no harm to the environment or public health. However, there can be some negative impacts on the surrounding environment if pesticides or excessive water are used during the growing season.
Regulations on hemp production vary by state. All producers should check with their state prior to growing or processing hemp. The growth of hemp for marijuana is only legal in some states, while the growth of hemp for CBD oil and other products is strictly regulated at the state and federal level. See more about the USDA regulations on hemp production here.
Hemp is in high demand and can be used in a variety of products, but is especially popular for natural medical products for the treatment of anxiety, depression, seizures and even assistance with the negative effects of cancer treatments. Hemp with high CBD content has a variety of industrial and commercial issues that make it a valuable product.
A wide variety of marketable products can be made from hemp and CBD oil, including paper, rope, textiles, biodegradable plastics, health food, natural treatments and even some construction materials and fuel.
Thorough and fast drying of hemp results in a higher quality product for processing or market. Our drying systems allow growers to dry hemp much faster, resulting in a product ready for CBD oil extraction or other industrial or medical purposes.
Since hemp was legalized in the 2018 Farm Bill, interest in growing industrial hemp for CBD production has skyrocketed. When properly dried and processed, CBD oil can be extracted from the hemp plant for use in a variety of products. While most people associate hemp only with medicinal uses, the material can also be used in textiles, paper, construction, and even fuel.
The U.S. Hemp industry produced approximately $820 million in revenue in 2017 and is expected to grow at least 14% by 2022, while the global hemp market is expected to reach over $10 million by 2025. This rapidly growing market offers a promising option for farmers looking for a product with constantly expanding potential.
Rotary drum drying machine is widely used in organic fertilizer making plants. Its main function is drying different kinds of fertilizer raw materials or final pellets into appropriate moisture content. The rotating drum dryer equipment is a kind of necessary equipment for all kind of organic fertilizer and compound fertilizer producing factories. Using it, the post management of fertilizer products can be much easier and efficient.
Our rotary drum drying machine consists of a rotary drum, lifting plates, transmission, support device and sealing ring. The dryer mainly is a slightly sloping drum. The fertilizer materials are added from the higher end, the hot flue gas and the material flow into the drum at the same time. With the rotating of the drum, the organic fertilizer materials will move to the lower end of the rotary drum.
There are many lifting plates on the inner wall of the drum, which can pick up and sprinkle the fertilizer materials down, so that the contact area between the materials and the airflow is enlarged to improve the drying efficiency. At last, the dried product flows from the bottom outlet to the next procedure.
1. High degree of mechanization brings it larger working capacity. Meanwhile, it consumes lower fuel and when working, it doesnt need people to operate. That can greatly reduce your cost on hiring operators. 2.

It has excellent application to different fertilizer materials such as poultry manure, livestock, mushrooms, straw powder, saw dust and so on. No matter which kind of materials, our rotating drying machine can work well for you. 5. While the fertilizer materials are drying, our drying machine can also sterilize and deodorize them. That not only makes fertilizers with suitable moisture, but also makes them have better quality.
In wet granulation method fertilizer making line, the drying machine is very helpful to dry fertilizer granules. As we know, the raw materials granulated by wet granulation equipment always have high moisture. Before granulating, the materials always need to be dehydrated with about 30% moisture content by the solid-liquid separator machine. But this value is not suitable to the final granules. To bring granules more compact structure and improve their hardness, the drying machine is needed. After drying, its much easier to transport and store the fertilizer granules.
Fresh chicken manure always has high moisture content. Before making them into fertilizer, its very necessary to reduce the moisture content. If you have a small scale factory of making chicken manure fertilizer pellets, you can choose our small drying machine. It can dry 1-5 tons of chicken manure per hour, the power consumption is 7.5 kw/h. Unlike the solid-liquid separator machine reducing the manure moisture content to about 30%, it can dry chicken manure to a very low moisture content at one time. You can make the dried chicken dung into pellets directly by using dry fertilizer granulating machine. With it, the process of your small chicken litter fertilizer plant will be more simple, which can save you a lot of money.
For 5-12t/h complex fertilizer production line, we have medium capacity drying machine can work for you. Its can dry the final compound fertilizer granules. Our customers always use them for limestone, sulphur or npk fertilizer plants. With high working efficiency, it can bring the pellets better hardness, prevent the compound balls from caking. The fertility can be more stable.
