Fertilizer Rotary Drum Dryer Introduction
The granular fertilizer formed by the fertilizer granulator has high moisture content and shall be dried to meet the standard. Rotary drum drying machine is mainly used for drying fertilizer with certain humidity and particle size in the compound fertilizer and organic fertilizer production. The dryer drum is also suitable for drying other materials. After drying, the moisture content of compound fertilizer will be reduced to 2%-5% from 20%-30%, while the moisture content reducing range for organic fertilizer is from 40%-10%. Rotary dryer shall be used combining with cooling machine, as fertilizer granules after drying has high temperature, which is not good for storage.
Fertilizer Rotary Drying Machine Features
1. Strong applicability for granular fertilizer with various properties.
2.Reasonable distribution and angle of lifting plate ensure full contact between the materials and hot air, high heat utilization rate, evenly drying effect.
3. Multiple models available for different capacity, and also can be customized.
4. The rotating speed of the cylinder can be adjusted according to your requirement.
5. The riding wheel, gear and lifting plates adopts high quality wear-resistant materials, greatly prolonging the service life of the machine.

6. The main motor and speed reducer adopt ISO National Free-inspection Product, having reliable quality.
7. Easy operation, easy maintenance, low energy consumption, stable operation.
Fertilizer Rotary Dryer Wide Application
1. Rotary drum dryer is suitable for drying granular organic fertilizer and compound fertilizer in the fertilizer production line.
2. Rotary dryer is suitable for drying various animal manure like chicken manure, cow dung, pig manure, duck manure, etc.
3. Rotary drier is suitable for drying crop straw, forage grass, leaves, fish meal, vinasse, herb residue, fruit residue, soy sauce residue, bagasse, turf, sludge, slaughtering leftovers, etc.
4. Rotary dryer is suitable for biomass pellet industry for drying sawdust, wood chips, wood shavings, etc.
Working Principle of Rotary Drum Dryer Machine
1. The main motor drives the triangle belt and belt pulley, and transfers to the driving shaft through the reducer. The pinion which is installed on the driving shaft engages with the gear fixed on the machine body, working in the opposite direction to make the machine work.

2. The rotary drum is slanted slightly with an angle of 2-5 degree. By the belt conveyor, the wet materials from the granulator are sent into the cylinder dryer through the feed hopper at the higher end, meanwhile the hot air produced by the hot blast stove enter into the dryer drum under the suction of the draught fan. The hot air can either enter from the feed end(known as co-current flow), or from the discharge end(known as counter-current flow).

3. With the rotation of the cylinder, the materials flow down to the lower end with the effect of gravity. The lifting plates fixed on the inner wall of the drum dryer lift the materials continuouly, forming a uniform material curtain, which fully contact with the hot air and exchange heat, the moisture is evaporated, achieving the aim of drying. The dried materials are discharged through the outlet at the lower end and sent to the cooler by the belt conveyor. The tail gas enters into the dust settling chamber.
