Rotary Drum Dryer
DRUM DRYER
EMCC’s dryer can be customized according to customers’ different product needs to achieve the best results.
We can design the length-to-diameter ratio of the cylinder, the lifting plate structural form and quantity, the flow direction relationship between hot air and material, the hot air inlet temperature, etc..
The fertilizer granules from the former granulator generally contain 6%-16% or even higher moisture, which needs to be dried to meet the moisture content standards, so as to meet the requirements of storage and fertilization. At present, the most commonly used drying equipment is the rotary dryer.
WORKING PRINCIPLE
The working principle of the rotary drum dryer is that under the action of dry air, the material rolls in the rotating drum to achieve the drying effect.
Rotary drum dryer is an inclined horizontal rotary cylinder, with a supporting device, a transmission device, a cylinder and a sealing structure such as inlet and outlet device.
The position of the drum is slightly tilted horizontally to allow gravity to help the material pass through the drum dryer. As the drum rotates, the lifting device picks up the material and drops it through the air stream to maximize heat transfer efficiency. When handling clumps, the rotation effect of the dryer can also further round and polish the granules.
FEATURES
Diameter: 0.8– 4.6m (2.625′ – 15.092′)
Capacity: 1 TPH – 200 TPH
The lifting device designed according to the specific situation can maximize the thermal conductivity between the material and the hot air flow.
A variety of materials are available, stainless steel optional for long service life.
Suitable heat sources can be recommended, such as fuel oil, heavy oil, natural gas, liquefied petroleum gas, coal or biomass, etc..

APPLICATIONS & MATERIALS
The rotary drum cooling machine is the most important cooling equipment in industrial cooling. It can handle a variety of raw materials and it is suitable for almost any industry requiring industrial cooling solutions, such as:
Building aggregate | Inorganic chemical | Paper sludge | Rubber particle |
Biosolids (municipal sewage waste and sludge) | Limestone | Plastic particle pellets and grains | Salt and sugar |
Fertilizer | Manure | Potash fertilizer | Sand |
Fly ash | Ore and concentrate | Regenerated dust | Steel mill slag |
Gypsum | Organic chemicals | Roof grain | Urea particles and crystals |
