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. Drum cylinder 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.
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. Drum granulator features:
1, The granulate rate is 70%, there is a small amount of returns, return product particle size small, can be granulated again.
2, Put into the steam heating, improve the material temperature, the material into the ball after the water is low, improve drying efficiency;
3, with rubber engineering plastics for lining, raw materials is not easy to stick, and play a role in anti-corrosion insulation;
4, large output, low power consumption, low maintenance cost.
