CDRG Series Chemical Dry Roller Granulator
Chemical dry roller granulator adopts dry extrusion technology, which is suitable for water cut. The powder less than 2% is compressed into tablets, and then crushed, granulated and sieved art, make pieces of bulk materials into granular materials that meet the use requirements.
Dry roll granulation nmainly relies on external pressure to force the mateiral to pass through two. A reverse rotaing roller gap, compressed into pieces. During the rolling process, the material. The actual density can be increased by 1.5-3 times, thus reaching certain strength requirements.

Product Working Principle
1. Various dry powder materials are added from the top of the equipment, degassed and pre-pressed by spiral into two equal rollers, the rollers rotate relatively, the materials are forced to be sent between the two rollers, the rollers bite the materials into the nip: the materials are compressed, and after the materials pass through tthe compression zone, the surface tension and gravity of the materials naturally separate them. The separated finger-shaped briquettes enter the granulator to be crushed by the rotary knife row, and the crushed materials enter the granulator to be sieved by the rotary vibration sieve through the rolling knife row. Qualified products are transported to the finished product warehouse by a conveyor. The powdery undersize material is sent back to the raw material bin for secondary rolling by a conveyor, and the extrusion pressure can be adjusted by the pressure of a hydraulic oil cylinder according to the needs of granulation operaion.
2. Sheet, strip and oblate materials can be obtained by changing the grooving form of roller surface.
3. When the press block, granular material between two counter-rotating rolls by compaction, briquetting binder can be used.
