Double roller granulator, also called roll granulator, double roll granulating machine, is widely used for organic and inorganic fertilizer production.
Roller granulator Features
It could compress directly material into the powder particles at normal temperature, not only to production of urea ammonium bicarbonate, chloride, ammonium phosphate, potassium chloride and other materials for the multielement compound fertilizer, and also applies to rare earth magnetic fertilizer granulation, without drying equipment, particle high intensity.No waste discharge, operation stability, reliable operation and easy maintenance.

Application of double roller granulator
Wide adaptability of raw materials for compound fertilizers, pharmaceuticals, chemicals, feed, grain and other raw materials, high rate of product into tablets, can produce a variety of high concentration, many types, including organic fertilizer, inorganic fertilizer, bio-fertilizer magnetic fertilizer, etc. in particular, rare earth compound, potassium, ammonium bicarbonate fertilizer granulation series to fill the gap, ranking the leading domestic market.

Working principle of roller granulator
Two rollers rotate in reverse, materials between rollers are compressed, the intermediate products are bar shape / sheet, then the crusher will crush the bar shape products into irregular granules, finally using the rotary screen to sieve standard products, non- standard products will be recycled mix with new material for the next granulating process.
