Rotary dryer is the fertilizer drying equipment commonly used in fertilizer production line. Rotary dryer is a kind of drying machine that processes a large amount of materials and is suitable for drying large particles in the chemical, mining and metallurgical industries, as well as drying of powdery and granular materials with special requirements. Rotary drum dryer has the advantages of large production capacity, wide application range of raw materials, small fluid resistance and easy operation. Rotary drum dryer is generally suitable for granular materials.
Roller dryer is suitable for the process of fertilizer production line
In the fertilizer production line, the wet fertilizer particles that need to be dried are sent to the hopper by belt conveyor or bucket elevator, and then enter the feeding end of the dryer through the hopper. The feeding end of the drum dryer is slightly inclined higher than the discharging end, which is a slightly inclined rotating cylinder in shape. The material enters from the higher end of the dryer and the hot air enters the dryer together. With the rotation of the cylinder, the material moves to the lower end under the action of gravity. During the forward movement of the wet fertilizer in the dryer barrel, the heat of the heat carrier can be obtained directly or indirectly, and the wet material can be dried, and then sent out through the belt conveyor at the discharge end.
The drum dryer device facilitates the drying of fertilizer
The inner wall of the cylinder of the drum dryer is equipped with a sheet, whose function is to copy and sprinkle the material, increase the contact surface between the material and air flow, and improve the drying speed of fertilizer. In the fertilizer production line, usually the gas produced by the dryer also needs to be trapped by the cyclone dust collector to prevent these gases from entering the air and polluting the environment.
