Efficient sanding structure

Abstract

The invention relates to the field of sanding, in particular to an efficient sanding structure comprising a grinding shell. A driving grinding roller is arranged in the middle of an inner cavity of the grinding shell. The outer portion of the driving grinding roller is provided with driven grinding rollers at equal angles. The driving grinding roller and the driven grinding rollers are all of a circular truncated cone structure. The side wall of the driving grinding roller is provided with a plurality of holding grooves at equal intervals. An auxiliary rollers are arranged in the holding grooves. Each auxiliary roller is rotationally connected with the driving grinding roller at the axis position through a rotating shaft. The longitudinal height of the driving grinding roller is larger than that of the driven grinding roller. The inner cavity of the grinding shell is provided with a precise grinding bin located at the bottom of the driving grinding roller. The outer wall of the rotating shaft of the driving grinding roller is provided with a dispersing disk located at the position of the precise grinding bin. A coarse grinding bin is arranged above the precise grinding bin. The efficient sanding structure solves the problems that by the adoption of a traditional sanding machine, primary smashing is not conducted before sanding, so that a dispersing disk is prone to getting stuck, and the work efficiency is low.

Description

technical field [0001] The invention relates to the technical field of sand grinding, in particular to a high-efficiency sand grinding structure. Background technique [0002] The sand mill adopts the eccentric disc grinding structure and is arranged in a certain order. This system overcomes the shortcomings of the uneven distribution of the grinding media of the traditional grinding machine, so that the grinding media can obtain the maximum energy transfer, and the grinding efficiency is high. Cooling mechanical seal, good sealing effect and reliable operation. The separation system adopts a large flow LDC dynamic slit separator. Under the condition of large flow, the discharge port will not be blocked, the flow area is large, and the gap range is 0.05-2.0mm. Use grinding media above 0.1mm. [0003] The traditional sand mill has not undergone primary crushing and then sanding, which leads to the easy jamming of the dispersion disc and low work efficiency. Contents of the...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the traditional sand mill has not undergone preliminary crushing, and then performs sand grinding, which leads to the problem that the dispersion disc is easy to be stuck and the working efficiency is low.
