Rotary Drum Dryer Introduction
rotary drum dryerRotary Drum Dryer is a kind of internal heating conduction drying machine.It is widely used in food industry, chemical industry, pharmaceuticals industry, etc. In fertilizer production, it main application is to dry compound and organic fertilizer granules, and is installed behind fertilizer granulator. After drying, the humidity of fertilizer granules will decrease from 20%-30% to 2%-5% and for bio-organic fertilizer, the moisture content will decrease to 10%. With ideal drying effect and high efficiency, rotary drying machine is the best choice for mass compound fertilizer production.

Working Principle of Fertilizer Drying Equipment

When the machine starts working, since the drum is slightly tilted, the wet materials flows into the hopper of the rotary drum dryer by belt conveyor or bucket elevator, meanwhile the hot air produced by the hot blast stove enters into the dryer drum, thus making the materials and the hot air mix completely. While the drying machine is rotating, the well-dried materials are collected from the other side and sent to the cooler by the belt conveyor.

Features of Organic Fertilizer Dryer Machine
1.High heating efficiency. Since the heat-transfer mechanism of this organic fertilizer dryer belongs to heat conduction, the conducting direction is concordant in the whole operating process, therefore most of the heat is used for drying except for the loss of heat radiation. The heating efficiency can reach 80%-90%.
2. High operation flexibility and wide application. Changing one of the many factors that affect drum drying, such as drum speed, material properties, the drying efficiency will be different.This advantage makes drying machine suitable for the different drying requirements and productivities of multiple materials.
3.Short Drying Time. Usually, the drying period of the fertilizer only has 10-300 seconds. It is very suitable for heat-sensitive materials.
4.High drying rate. Because the resit film inside the drum is very thin and the direction of heating conduction is concordant, the surface of the film can keep intense evaporation of 20-70 kg·H2o/m²·h.
5.Fully automatic control, strong overloading capacity resistance.

Application of Rotary Drum Dryer
Rotary drum dryer can be use in many fields, including organic fertilizer&compound fertilizer, bio-mass pellet industry, feed and agriculture industry, building materials drying, metallurgy and chemical industry, mining industries. Most of materials from these fields are OK like manure waste, wood sawdust, straw,ores, crystals,etc. So in fertilizer production, it can excellently finish its task.
