Grinding device based on quartz powder earlier stage treatment

Abstract

The invention discloses a grinding device based on quartz powder earlier stage treatment. The grinding device comprises a grinding unit and a bearing unit, quartz powder and deionized water enter from a feed port to be ground, and flow out from a discharge port through filter screen gaps of layering assemblies after being fully ground, and the bearing unit supports the grinding unit and enables a roller to do up-and-down reciprocating motion, so that the quartz powder can be better ground. According to the grinding device, through cooperation of a first filter part and a second filter part, the filter screen gaps of the layering assemblies can be adjusted, and the grinding precision of the quartz powder can be adjusted according to needs; a plurality of layering assemblies are arranged, so that quartz powder in the roller can be subjected to gradient grinding, and the efficiency is higher; and through a reciprocating piece, one end of the roller can do reciprocating lifting-lowering motion, so that a ground object, a grinding body and water flow on the inner wall of the roller vibrate back and forth, and the quartz powder is ground more sufficiently.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a grinding device based on pre-treatment of quartz powder. Background technique [0002] Quartz powder (same as quartz sand) is also called silica powder. Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is silicon dioxide. The color of quartz sand is milky white, or colorless and translucent, with a Mohs hardness of 7. Cleavage, shell-like fracture, grease luster, its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750 ℃. After the quartz stone mined from the mine is processed, the product with a fineness below 120 mesh (less than 120 mesh) is called quartz sand, and the product with a fineness of more than 120 mesh is called quartz powder. [0003] The existing ground quartz powder is discharged from the outlet of the grinding devi...

AI Technical Summary

Problems solved by technology

[0003] The existing ground quartz powder is discharged from the outlet of the grinding device based on the pre-treatment of the quartz powder, which may cause insufficient grinding of the quartz powder and the problem that the fineness of the grinding cannot be adjusted. Secondly, when the grinding device is grinding, due to the grinding The unit is usually stationary so the grinding bodies inside it may clump together, and in some places there are no grinding bodies at all and the quartz powder cannot be ground well
