AI Technical Summary

Technical Problem

In the prior art, the grinding particle size of the oil feed is not fine enough and has poor uniformity, resulting in a low stirring oil output rate and waste of resources.

Method used

The coarse grinding mechanism and the fine grinding mechanism are combined. The coarse grinding mechanism is coarsely grinded through a cutting roller shaft composed of two sets of cutters. The fine grinding mechanism is fine grinded through a feeding roller with spiral grooves and a grinding roller, and combines feeding rollers and grinding rollers of different rotation speeds and rotation directions to form a cutting force to refine the material.

Benefits of technology

Through the two processes of coarse grinding and fine grinding, the grinding particle size of the material is significantly reduced, and the uniformity of the particle size is improved, thereby improving the stirring oil output rate, reducing resource waste, and realizing fully automatic continuous feeding and a highly automated grinding mechanism.

Abstract

The invention relates to the field of crushing structures, in particular to a grinding mechanism which comprises a coarse grinding mechanism and a fine grinding mechanism, and materials are sequentially ground by the coarse grinding mechanism and the fine grinding mechanism and then enter a stirring mechanism; the coarse grinding mechanism comprises a coarse grinding chamber, a first cutter roll shaft, a second cutter roll shaft and a coarse grinding driving assembly, the first cutter roll shaft and the second cutter roll shaft are rotationally installed in the coarse grinding chamber through the coarse grinding driving assembly and are arranged side by side, and a plurality of annular second discharging cutters are fixedly arranged on the second cutter roll shaft; the accurate grinding mechanism comprises an accurate grinding chamber, a feeding roller, a grinding roller and an accurate grinding driving assembly, the top of the accurate grinding chamber communicates with the coarse grinding discharging opening, and the feeding roller and the grinding roller rotate in the direction close to each other and are different in rotating speed; a first spiral groove is formed in the peripheral side wall of the feeding roller, and a second spiral groove is formed in the grinding roller. The device has the effects of reducing the grinding particle size of the material and improving the uniformity of the grinding particle size of the material.
