Introduction of Double Roll Extrusion Granulator

What is a double roller extrusion granulator？
Double roller extrusion granulator is particularly effective in granulating ammonium bicarbonate, ammonium chloride and monoammonium phosphate. The granulation rate can reach 85%. It adopts no drying process, room temperature granulation, one-time molding, low investment, quick effect, good economic benefit and small footprint. The roller granulator has wide adaptability to raw materials and can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical, feed, coal, metallurgy, etc. It can produce various concentrations and types of compound fertilizer. The granules made are flat and round. There is no emission of waste water and waste gas.
 
Definition of extrusion
The working process of a roller extrusion granulator represents the extrusion granulators. The dry material is compressed under pressure into a hard and dense block, which is the extrusion process. The block material is crushed and sieved into granules, which is the process of granulation. The effect of extrusion is to squeeze out the air between the particles and to bring the particles close enough to create an interactive force between the particles.
