The ANDRITZ SEPARATION belt dryer/cooler BDC is available with gas-, oil-, or steam heating and can be applied for bulk material or food. The drying of the product takes place on a ventilated conveyor belt. Depending on the type of product we can offer either a single-belt dryer or multi-belt dryer.
The patented ANDRITZ AG belt drying system (BDS) is characterized by its flexibility and ability to use a wide range of energy sources, particularly low-grade waste energy. BDS can be used for drying a broad range of products, such as industrial and municipal sludge, cow manure, biomass, as well as pre-treated municipal solid waste.
Drying and cooling take place in the product chamber, only by convective heat and mass transfer between the fluidization gas and the product. Two different designs are available, for normal and high temperature applications.
The fluid bed drying system with direct feeding converts dewatered sludge into almost dust-free granules with > 90% DS. The thermal heat for evaporation of the water is transferred indirectly by a heat exchanger immersed in the fluid bed. The fluid bed dryer is integrated into an inert gas loop system.
The ANDRITZ drum drying system, DDS, dries and granulates different types of municipal, industrial, and agricultural sludges. The dewatered sludge is granulated in a mixer tailored to the application. It is then dried in the triple-pass drum (three concentric cylinders revolving around a joint axis) in a convective drying process to < 10% residual moisture. The sludge is conveyed pneumatically by the stream of hot gases, ensuring an evenly dried, pasteurized product.
This type of fluid bed is used for salts and minerals, as well as for basic chemical products, mainly for lower line capacities. It is characterized by the vibrating design of the fluid bed to enhance fluidization of the products with a wide particle size distribution range.
The spray granulation process converts a water-containing solution, paste or suspension or a melt into a granule. The granulation and the drying processes take place at the same time. Any kind of crystallization and mechanical dewatering equipment can be replaced by an SGS type fluid bed. The final product granules are dust-free and easy to handle.
The rotary drum dryer is suitable for drying woody biomass, agricultural products, and municipal solid waste (MSW). For the production of alternative fuels as well as in the area of waste-to-energy, ANDRITZ Vandenbroek rotary drum dryers are applied to decrease the moisture of the material to the desired level fo downstream process steps.
Why Use Sludge Dryers in Your Wastewater Treatment Facility? Wastewater treatment plants face an uphill battle with disposing of the biosolids produced in their operations. Transporting costs are significant primarily because of the high water content of the material. One way to mitigate costs and turn the biosolids into something useful is to utilize sludge dryers.
Uzelac Industries is a leader in engineering customized drying systems for rendering, biomass, biosolids and residuals, waste-to-energy, and alternative energy industries. We work with you to design a product that meets your unique situation and will last for years to come.
Both industrial and municipal wastewater treatment plants produce nutrient-rich organic materials when the sludge has been appropriately treated and processed. The material is dried, and the best part is that the biosolids can be used as fertilizer for the soil.
Often a sludge dryer is used for the final drying of sludge or digestate. Dewatered solids enter the dryers inlet and begin the process of drying as heated air is applied. The airflow moves the dewatered product into a collection system. The hot air and dried product are separated with the product moved to a storage area for further processing, such as screening or sorting.
As cost-effective and environmentally conscious managers, utilizing a sludge dryer in your facility makes sense. Here are some benefits to consider: Granules are much easier to handle, making transportation a breeze compared to water-laden sludge. Since the granules are dry and do not add moisture to the soil, they can aid in preventing runoff. Increase your facilitys revenue as you sell your premium biosolid fertilizer.
Refined sludge has many applications that enhance the environment. Here are a few: The most common application is that of fertilizer for crop harvesting. Golf courses benefit from using dried sludge granules as a top dressing on their fairways. New parks and athletic fields benefit from the soil conditioning the product brings. It is a good substitute as a final landfill cover.

Super Rotary Sludge Dryer is a newly developed sludge recycling technology by Benenv.We have over 40 years experience on sludge drier and carbonizer.It is the result of the painstaking efforts of Japanese experts and Chinese professors in incineration, drying, carbonization field. This device uses clean energy as heating & drying energy, and direct heating method, during which no dioxins and other toxic substances are produced.Compared with direct sludge incineration, super rotary dryer requires less energy with low carbon emissions, in line with national low-carbon environmental requirements.
Appearance video Fine workmanship, beautiful products, whole body stainless steel, frosting process, pay attention to details, only do boutique. Reducer Use Nissei or Nord brand reducers, industrial quality from Japan and Germany. Mud inlet The round-hole screen is used to prevent large particles and garbage from entering the dehydration body, reducing machine wear and improving machine service life. 7-shaped blade The mixing is more complete and the flocculation effect is better. Industry standard wiring The mixing is more complete and the flocculation effect is better.
The super sludge dryer is equipped with a unique crushing and stirring device in the drying cylinder, and the rotatable cylinder itself has the function of crushing and stirring. The crushing and stirring device can crush and disperse the sticky and massive materials, so as to increase the contact efficiency of hot air, and the cylinder can obtain the dry finished products with uniform quality (particle size of 1-5mm) in a short time.
The characteristics of sludge are very sticky, and there is a special sticky phase in the drying process (moisture content is 40% - 60%). In this very narrow transition section, the sludge is very easy to agglomerate, the surface is hard and hard to crush, but the inside is still slime. However, the equipment has a unique crushing and stirring device. When the sludge is dried in the cylinder, the device will rotate at a high speed, and the sludge in the sticky phase will be completely crushed into small particles, so as to improve the drying efficiency.
Through the composite effect of crushing and stirring device and cylinder rotation, the total heat transfer coefficient is increased to 2-3 times of that of ordinary rotary dryer (UA = 200-600w / m2k).
Due to the change of exhaust temperature with the change of evaporation, the device adopts corresponding control measures in the design and construction to cope with the change so as to ensure the control and management of product moisture content. Therefore, the device can be applied to materials with different properties, floccules and lumps, etc.
The mechanism is simple, few parts need to be tested and easy to maintain. The operator uses the touch operation panel for production operation. If there is a fault, there will be a fault prompt on the operation panel.
After the material is crushed, the contact area between the material and the hot air is increased, the hot air is fully utilized, and the exhaust hot air is recycled, which greatly reduces the energy consumption. The dried product is a particle with a particle size of 1-5mm and high calorific value. If it is processed, it can be used as fuel.

Sludge Dryersmanufactured byMet-Chemare designed for small, medium and large quantity sludge generators. These dryers can fit under the filter press for direct loading or can be located elsewhere in the plant. The sludge is dried by the heated liner of our unit while it is broken-up and circulated by our spiral blade system. The dryer liner uses indirect heat sources from steam, electric strips or gas fire. Our preheated airflow system draws the moisture off the top of the internal dryer and out through our wet scrubber system. After typically 4-6 hours of drying time (depending upon the type and wetness of the sludge) the dried material is removed by simply opening our discharge panel underneath our units for gravity discharge into a container. Another option is to include a conveyor auger to move the sludge to an elevated container. You have options depending upon your particular space requirements or restrictions.
Our use of and indirect heat provides an even heating surface and allows for tighter temperature control making it less likely to cause the sludge to burn or smolder. It also eliminates the danger associated with an open flame.
