2-6mm Rotary Drum Granulator For Compound Fertilizer With Round Ball Shape

Working Principle of drum granulator
The belt and pulley are driven by the main motor, and the driving shaft is driven by the reducer. The pair of open-gears installed on the driving shaft and the big gear ring fixed on the machine body are combined and work in opposite direction. The materials are fed from the inlet and are made into particles with the drum rotating under certain conditions, the particles finally flow out through the outlet. With the continuous materials feeding and continuous rotating to achieve the mass production.

Advantage of drum granulator

1. Low investment, good economic benefit and reliable performance;
2. Low power, no waste discharge, stable operation, convenient maintenance, reasonable process, advanced technology and low production cost;
3. High pellet strength, good appearance, corrosion resistance, wear resistance, low energy consumption;
4. The granulation rate is up to 70%, and the returned material can be re-granulated;
5. The drum is lined with special rubber sheet or acid-resistant stainless, which can automatically prevent materials from agglomerating and sticking to the drum wall without traditional scraper device.

Introduction of drum granulator

Rotary drum granulator is a kind of fertilizer granulator machine can make the material into a specific shape. Drum granulator is one of the key equipment of the compound fertilizer industry. It is suitable for large-scale production of cold &hot fertilizer granulation line and high and low concentration compound fertilizer line. Main work method for aggregate wet granulation, through a certain amount of water or steam, the basis for fertilizers in the cylinder body after full wet chemical reaction, in a certain liquid under the conditions of the rotating cylinder with campaign, reunion between particles to produce extrusion pressure of material into a ball.

The cylinder of drum granulator adopt special rubber lining or acid stainless steel plate, has realized the automatic except scar, tumor, cancel the traditional scraper device. The machine has the characteristics of high ball strength, good appearance, corrosion resistance, wear resistance, low energy consumption, long service life, easy operation and maintenance.
Rotary drum granulator machine ventilation with steam, gas, or adding phosphoric acid or ammonia nitrogen and phosphorus ammonia solution slurry, coarse whiting slurry, within the cylinder with the fertilizer granulation process of chemical reaction and heat; Or cold added a small amount of moisture content of compound fertilizer granulation process. The need of granulating material through the rotation movement of the cylinder, the cylinder didn't scroll spin, sticking together under a certain humidity, temperature, into a ball, complete system process.
