[0022] The staff transports the stones to be processed into the cylinder 3 through the feed cylinder 171. The inclined structure of the feed cylinder 171 prevents accumulation during feeding, and the horizontal structure allows the stones to accumulate briefly. The stones that enter later give thrust to the stones in front, so that the stones in front slide through the arc plate 173 and the discharge plate 172 and fall into the cylinder 3 for grinding. The column 174 makes it easier for the stones to flow and disperse. The driving motor 14 drives the rotating shaft 12 to rotate, and then drives the cylinder 3 to rotate on the rolling support wheel 2 through the cooperation of the small gear 13 and the large gear 11. The stones inside the cylinder 3 are actually ground under the action of the grinding roller 16 and the grinding ring 15. After grinding and crushing, the balancing mechanism 19 keeps the grinding roller 16 in the correct position to reduce the vibration and displacement during the grinding process.

The column 174 makes the stone easier to flow and disperse.

The balancing pipe 196 is installed between the two groups of pressure arms 193; the pressure arm 193 keeps the grinding roller 16 in the correct position to reduce the vibration and displacement during the grinding process. The main function of the cylinder 195 is to balance the external load so that the load remains in a balanced state, which can effectively reduce or eliminate the influence of the load on other components. The balancing pipe 196 balances the axial thrust of the grinding roller 16 to reduce the axial movement of the grinding roller 16.

[0029] Working process:

[0030] Before processing, the driving motor 14 and the motor 183 are turned on.

The column 174 makes it easier for the stones to flow and disperse. The driving motor 14 drives the rotating shaft 12 to rotate, and then drives the cylinder 3 to rotate on the rolling support wheel 2 through the cooperation of the small gear 13 and the large gear 11. The stones inside the cylinder 3 are ground and crushed under the action of the grinding roller 16 and the grinding ring 15. The partition 4 prevents the stones from being discharged from the discharge hopper 10 without being ground. The pressure arm 193 keeps the grinding roller 16 in the correct position to reduce the vibration and displacement during the grinding process. The main function of the oil cylinder 195 is to balance the external load so that the load remains in a balanced state, which can effectively The influence of the load on other components is reduced or eliminated. The balance pipe 196 balances the axial thrust of the grinding roller 16 and reduces the axial movement of the grinding roller 16. After the grinding, the stone is thrown upward under the action of centrifugal force. The stone that meets the grinding requirements falls into the conveying cylinder 181 through the mesh plate 184. The motor 183 drives the conveying auger 182 to rotate to realize the transportation of the stone, and then falls onto the guide plate 187 through the discharge port 1811. Through the guiding effect of the guide plate 187, the stone falls into the discharge bin 41 and is finally discharged through the discharge hopper 10 for centralized collection and processing, which not only ensures the quality of stone grinding, but also realizes the rapid output of stone, realizes the continuous feeding and discharging of the cylinder 3 and the external feeding mechanism 17 and the discharging mechanism 18, realizes the automatic continuous production of stone, solves the problem of low intermittent production efficiency of the existing cylinder roller mill, and improves the production efficiency of stone processing.
