Calcite grinding mill workflow

1.After big block be crushed into small particle by the jaw crusher.

2.Fall into the silo through the bucket elevator,The electric magnetic vibrating feeder under silo evenly feed the material into the Raymond mill to grinding according to the set quantity of flow.

3.When the main machine of the Raymond mill is working, the grinding roller rolls tightly on the grinding ring under the action of centrifugal force. The material is scooped up by the shovel and sent to the middle of the grinding roller and the grinding ring. The material is broken into powder under the action of the grinding force. Then, under the action of the fan, the powdered materials are blown up and passed through the analyzer. The materials that meet the fineness requirements pass through the analyzer. The materials that do not meet the requirements are returned to the grinding chamber to continue grinding.

4.The qualified material go into the double cylone powder collector with the airflow,then transport to the discharge hole by the discharge screw, the excess air suction into pulse dust collectorby the negative pressure fan and discharge after reach the standard of the dust remove .

5.The finnal products transport to the cylinder silo by Pneumatic transmission device.

1. Large pieces of material are broken into small particles by the crusher and sent to the storage bin by the elevator. Then the materials are evenly sent to the middle of the upper turntable through the belt conveyor weighing scale.

2.The motor of the micro-grinding machine drives the spindle and the turntable of each layer to rotate through the reducer, and the turntable drives dozens of ring rollers to roll and rotate in the raceway of the grinding ring through the pin.

3.The material is scattered to the periphery of the circle under the action of centrifugal force, and falls into the raceway of the grinding ring by the ring roller punching, rolling, grinding and crushing. The suction effect of the high pressure centrifugal fan will draw the external air into the machine, and the coarse powder after the third layer of grinding will be brought into the separator. 

4.The snail flow generated by the rotating worm gear in the separator makes the coarse particle material fall back to the re-grinding, and the fine powder enters the cyclone powder collector with the air flow and is discharged by the discharge valve at its lower part, which is the finished product. 

5.The air flow with a small amount of fine dust is purified by the pulse dust collector and discharged by the fan and silencer.
