Rotary Drum Granulator for NPK Compound Fertilizer is a new generation of rotary drum granulator developed by our company staff according to construction experience. The machine has the features of beautiful appearance, simple operation, low energy consumption, long service life, uniform drying and convenient maintenance, etc., which is the most advanced granulating equipment in China. The product is suitable for large-scale production of cold, hot granule and high, medium and low concentration of compound fertilizer.

Characteristics of Performance

Innovate technology, and improved structure; the tube uses special rubber sheet lining or acid resistant stainless steel liner, realizing automatic removal of scar, deoma.

High wear resistance, convenient maintenance, high ball strength, good appearance, corrosion resistance, wear resistance, low energy consumption, long service life, convenient operation and maintenance。

Reasonable layout, advanced technology, small power, no three wastes discharge, stable operation, convenient maintenance.

High balling rate; the drying efficiency is high; the balling rate can reach 70%; there is a small amount of returning material, the size of returning material is small and can be regranulated. Steam heating to raise the material temperature.

Working Principle of Rotary Drum Granulator for NPK Compound Fertilizer

Electromotor drive the belt and pulley, then it is transmitted to the driving shaft by the speed reducer; by installing the open gear on the drive shaft, the open gear is fitted with the large toothed ring that is fixed on the body, achieving the working in the same direction. The material is added from the feed end and is inside the tube. The function of the special structure inside the tube is granulation, finally out of the outlet. Because of the continuous entry of materials, the continuous rotation of the granulator can achieve mass production.
