Horizontal Sand Roller Rice Machine

The equipment structure is compact, and the feeding port is much lower than the discharging port. When multiple equipment are processed in series, there is no need for a hoist to transfer the material flow between the equipment. This method can greatly reduce the crushing caused by the addition of a hoist, reduce equipment costs, and occupy a small area.

The combination of the spray air device and the external air network device allows for collision, rolling, and more even grinding and friction inside the grinding chamber due to the wind force. At the same time, the wind effect is also beneficial for removing bran and preventing blockage, reducing rice temperature. The lower end of the grinding chamber is equipped with a rotary impeller scraper with the same speed as the grinding roller, which has high cleaning efficiency and greatly reduces the residual amount of bran powder in the grinding chamber. Under the action of wind force, it is discharged more timely to the outside of the main machine.

The working principle of a sand roller rice mill is based on the grinding effect of the grinding wheel, which uses granular objects (such as sand) on the roller surface of the grinding wheel to grind grains into small particles such as rice or powder. Grinding wheels are usually composed of two parallel sand grinding wheels, one of which rotates to grind grains while the other remains stationary. When grains enter the gap between the grinding wheels, they are subjected to pressure and friction on the roller surface, and then ground into small particles.
