rotary dryer and cyclone clay design

rotary dryer with quote and working principle | fote machinery

During their practical applications, because the structure is more complicated, multi-cylinder dryers are difficult to maintain. Also, its materials are easily clogged when the moisture is high. Therefore, single-cylinder dryers are the most popular type in the market.

And according to the heat transfer mode between the drying medium and the wet material, the rotary dryer can be also divided into two different types: direct-heat rotary drum dryer and indirect-heat rotary drum dryer.

The heating medium of the indirect-heat rotary drum dryer is not contacted with the material directly. All the heat required is transferred to the material through the heat transfer wall. While the material directly contacts with the internal heating medium, and mainly dried by convective heat transfer. Thus, the latter is used more widely.

The material granularity is generally not larger than 50 mm. And with the strong adaptability to materials, it can process varieties of materials. Besides, because of its simple and reliable structure, the rotary dryer is the most popular equipment for drying.

It can not only dry magnetic, heavy and floating concentrates of metal and non-metallic ore, but also dry clay in the cement industry and slime in the coal industry. Besides, it can be used for drying powder and granular with special requirements, such as various crystals, light calcium carbonate, activated clay, magnetic powder, graphite, etc.

2. In the middle of the drum, there are lifting plates welded. By changing the angle of the lifting plate, the height of the lifting material can be reduced to avoid the deformation of the material.

The material is sent to the hopper by the belt conveyor or bucket elevator and then enters the drum through the feeding pipe of the hopper. Because of the inclination angle of 5 to the horizontal, the material can naturally flow into the drum.

To achieve the perfect drying effect and reduce investment costs, besides paying attention to equipment installation and operation, selecting a high-quality equipment manufacturer at the very beginning is a top priority.

rotary dryer systems: supporting equipment

Rotary dryers are used prolifically throughout bulk solids processing applications from fertilizers and soil amendments, to minerals, specialty chemicals and more. In fact, new applications in which rotary dryers are being implemented are constantly on the rise.

The typical support equipment that makes up a complete drying system is outlined below. In addition to our custom rotary dryers, FEECO can provide the listed equipment as part of a complete drying system.

All direct rotary dryers must be equipped with exhaust gas handling equipment. The level of exhaust gas handling required is based on the unique emissions requirements of the material being processed, combined with local, state, and federal regulations. Design of the exhaust handling system will differ based on the level of treatment needed.

Depending on the requirements, the exhaust gas handling system typically consists of one of the setups listed below. However, no matter what type of exhaust gas handling system is employed, an induced draft (ID) fan will be required.

For cyclone and scrubber applications, the ID fan can be positioned between the cyclone & scrubber or after the cyclone and scrubber. It is desirable to place it after the cyclone (and before the scrubber) when the exhaust gas contains chemicals that become corrosive when mixed with water from the scrubber. By doing this, the fan can be fabricated from carbon steel as opposed to a special alloy.

The baghouse or bag filter collects any particulates that may have become entrained in the process gas and carried out through the exhaust air, which can especially be an issue when a high airflow velocity is combined with a fine material. Preventing the release of captured particulates into the atmosphere is a critical part of emissions control.

Not only do baghouses aid in air pollution control, but they can also be used to reduce wasted product; the dust and fines collected by the baghouse can often be recovered and reintroduced to the process, mitigating any waste lost as dust. In some operations, operators may choose to implement an agglomeration circuit to process baghouse fines or send them back to the process as recycle.

Cyclones use centrifugal force to separate out larger dust particles. Incorporating a cyclone into the system prior to the baghouse increases dust and product recovery. For this reason, this system is particularly beneficial when maximum recovery of dust and product is desirable, such as when working with a highly valuable material.

Cyclones first remove the bulk of the larger particulates, leaving the baghouse, which is not ideal for dealing with a lot of carryover, to filter out the remaining dust. As a result, this setup can help to prolong baghouse life and reduce the frequency of maintenance since the cyclone reduces the burden on the baghouse by handling the bulk of particulates. Furthermore, this setup allows baghouses to be effective in situations where they otherwise could not due to incompatible material characteristics (again because the cyclone removes the bulk of entrained material before the baghouse).

The scrubber utilizes a fluid solution (often water) to clean contaminants and particulates from exhaust gas. In this setup, the cyclone serves to remove the majority of the particulates, while the scrubber removes the remainder, along with any harmful chemical components.

The image above shows the discharge end of a rotary dryer. Ducting carries air and particulates out to a cyclone and baghouse, while a troughed belt conveyor collects material from the discharge to carry it to storage or transport.

In some settings, waste heat from various sources can be used to preheat combustion or dilution air to improve burner efficiency. The combustion air required to assist in the combustion reaction typically comes from a blower forcing air into the burner. The burner heats up the combustion and dilution air to produce the necessary process drying gas. An air-to-air or steam-to-air heat exchanger can be used to raise the temperature of waste heat, allowing it to be fed in as the combustion or dilution air, reducing the burden on the burner and increasing efficiency.

Combustion chambers are not required in all settings, but can be a valuable add-on. Combustion chambers serve to house the combustion reaction and direct the airflow into the dryer (either co-currently or counter currently).

Implementing a combustion chamber can offer a number of benefits. Perhaps most importantly, the addition of a combustion chamber can promote a quality product by preventing contact between the burner flame and the material being processed.

In addition to the immediate support equipment, various types of bulk material handling equipment will be required to transport material to and from the dryer. This might include screw conveyors, troughed belt conveyors, bucket elevators, feeders, etc.

Rotary dryers are a critical component in many industrial bulk solids processing applications. These units often require a range of support equipment to integrate them into a process and to meet air pollution requirements.

Rotary Dryer Working Principle 1. The mineral material is transported to the hopper by a belt conveyor or bucket elevator, and then the hopper feeder enters the feeding end through the feeding pipe. 2. The inclination of the feeding pipe should be greater than the natural inclination angle of the material, so that the material can flow smoothly into the mine dryer. 3. The dryer cylinder is a rotating cylinder tilted slightly to the horizontal line. The material is added from the higher end, and the heat-carrying body enters from the lower end. The heat-carrying body is in contact with the material in a countercurrent way. 4. As the cylinder rotates, the material is moved to the lower end by gravity. In the process of moving forward in the cylinder, the wet material is directly or indirectly given the heat carrier, which makes the wet material dry, and then is sent out through the belt conveyor or the screw conveyor at the discharging end. 5. The inside wall of the slag dryer is equipped with a copy board, which can copy and scatter the material, so as to increase the contact surface between the material and the airflow, so as to increase the drying rate and promote the advancement of the material. 6, after the heat carrier Dryer, the general need for the cyclone dust collector gas with the material captured down.

fertilizer dryer for sale | large-capacity rotary fertilizer dryer

Fertilizer dryers are used to reduce moisture content of all kinds of powder and pellet materials. You can use a Shunxin drum fertilizer dryer in many industries. For your reference, you can use a large capacity fertilizer dryer to dry clay, coal, mineral waste residue, iron powder, and so on. Whats more, rotating drum dryers play an important role in organic and compound fertilizer production line to dry powder or pellet fertilizer.

In powder fertilizer production lines, a rotary fertilizer dryer machine is installed after a crusher machine or a mixing machine. In pellet fertilizer production lines, you should place Shunxin drying equipment after the fertilizer granulator. The main part of Shunxin drying machine is a horizontal cylindrical drum. In the cylindrical drum, there are lots of fins that can scatter materials in the rotating drum. All parts of Shunxin rotating dryer machine are durable, so the fertilizer dryer is high-quality . In addition, the rotary drum drier is a kind of energy-saving industrial drying facility.

Shunxin experts design our rotating drier equipment reasonably and it has lots of stunning features. In the following content, Shunxin will show you some details about the design of our rotary drying machine.

You can not dry your materials only with a cylinder dryer. Shunxin rotating fertilizer dryer need to work with some corollary equipment. These equipment include burner, hot-blast stove, induced draft fan, cyclone dust collector and dust setting chamber.

Burners are the heating devices. Shunxin has two types of burners: gas-burning burner and dual-purpose burner. Gas-burning burner just can burn gas while the dual-purpose can burn both gas and diesel oil.

Hot-blast stove is another heating facility. Unlike Shunxin burners, a hot-blast stove looks like a sealed cubic room. The inner wall of it is covered with fire-clay bricks and the out part is covered with manganese steel plates. Shunxin hot-blast stoves are movable and it is easy to install them. In addition, we can customize hot-blast stoves in different sizes for you.

Induced draft fan is installed at the discharge part of cylinder drum dryer. It can continuously exhaust hot air in the drum drying machine. This is an inevitable corollary machine for drying powder and pellet materials.

You can use a cyclone dust collector to collect fine dust in the drying process. Out of the purpose of protecting environment, youd better equip this machine for your rotary drier. The collected dust will enter into a dust setting chamber.

Shunxin drum driers are energy-saving. They consume less fuel than other kind of industrial driers. The outer part of the cylinder drier equals to an insulating layer. That means the heat in the drum will not radiate out. In this way, the heat loss is less. Thus, Shunxin rotary drying facility is energy-saving.

Among these component parts of Shunxin rotating dryer machines, there are several vulnerable parts. The quick-wear parts include pinions and belts. Generally speaking, you need to change the pinions and belts of your drum dryer machine every half a year. If you maintain them in a proper way, you can use them for a longer time. For your information, you can also communicate with our sales to ask if they can provide you a set of quick-wear parts for free or in quite low prices.

There is no doubt that you should start the heating facilities at the first step. The materials to be dried will be put into the drying cylinder through a conveyor. Under the function of a induced draft fan, the hot air generated by the hot-blast stove or the burner will move quickly in the drying drum. In this process, the material will lose moisture rapidly. During the drying process, some fine dust will appear. You should use a cyclone dust collector to collect it in order to protect the environment. The collected dust will be centralized in the dust setting chamber. Finally, the dried materials will come out of the rotary drier from the discharge port. And the exhaust fan will exhaust air and water vapor out of the drum part.
