Case Description

 


DH series  Double roller granulator

WORKING PRINCIPLE

DH series dry roll press granulator machine adopts dry rolling technology to compress the powdery materials with moisture content ≤ 1% into pieces or tablets, then going through the processes of  breaking into granules and screening to make the lump materials into granules that meet the requirements of application. Dry roll press pelletizer mainly depends on the manner of external pressure to force the material  going through the gap between two relatively turning rollers  to compress into laminar particles. During course of roller pressing, the real density of materials can increase 1.5~3 times thus reaching certain demands of granular strength.
