Introduction of Rotary Drum Granulator
rotary drum granulation machineOur rotary drum granulator is used to produce multinutrient fertilizers (complex fertilizer), for example binary (NP, NK, PK) fertilizers and NPK fertilizers. Raw materials, such as ammonia, phosphate, nitrogen solution, sulphate phosphate slurry, triple superphosphate(TSP) slurry etc., can be added in the rotary drum to produce chemical reaction. Materials rotate in the drum, cohere with each other, and are turned into compound fertilizer granules at a certain temperature and humidity, accomplishing the whole compound fertilizer production process. It is usually used in compound fertilizer production line, with a high output rate, such as our 100,000 tons/year compound fertilizer production line, to meet the requirements of high yield production.

Features of Rotary Granulator
1. 70% fertilizer granules yield. Small returned materials, which is helpful to re-granulate.
2. Rotary drum of this compound fertilizer granulator adopts UHMW-PE as inside lining, which prevents wall sticking, and relieves work intensification.
3. During rotation, water can be added to intensity the materials adhesion.
4. High output, low energy consumption, and low maintenance cost. The largest production capacity can arrive 10 t/h.

Structure of Rotary Drum Compound Fertilizer Making Machine
Bracket:
the whole body is supported by bracket, so the whole structure adopts medium carbon steel plate, and has passed strict quality control. The most important thing is, as taking into consideration of higher friction during the machine working, we have selected high quality anti-corrosion, wear-resistant materials, which, to great extent, prolong the lifespan of rotary drum granulator.fertilizer granulator 6
Drive Assembly
The drive assembly is an essential part of the whole machine. The electrical motor and reducer is with high quality, and has passed ISO certification. The motor drives pulleys, and the reducer drives the main shaft, which makes the whole machine work.

Working Principle of Rotary Fertilizer Granulating Machine

The main electric motor drives that strap and driving pulley. Under the function of reducer, driving shaft rotates. Then the teeth of open gear being installed on the driving shaft, engage with those of big gear on the drum body. Materials are added into the rotary drum through raw materials feed (the slope of the feed system should higher than the angle of repose of materials). Due to drum body with an angle of incline of 2-2.5, under the influence of gravity and liner friction, raw materials keep doing circular motion and axis movement. During the rotation, raw materials are made into fertilizer granules by the special inner structure of rotary drum.
