Convenient-to-discharge sand mill for coating production

Abstract

The invention discloses a convenient-to-discharge sand mill for coating production. The sand mill comprises an outer cylinder and an inner cylinder and a first discharging opening, an overhaul door ismovably connected with the left end of the outer cylinder, connecting pieces are in welded connection with the middles of the left and right ends of a middle cylinder respectively, a fixing groove isformed in a fixing disc in an embedded mode, a convex block is in welded connection with the outer surface of a connecting roller, sand milling balls are evenly distributed in the inner cylinder, a first connecting hole is formed in the surface of a connecting cylinder, and a first connecting pipe is connected with the right end of the outer cylinder; and a second connecting pipe is fixedly connected with the right end of an air blower, an air outlet is formed in the upper end of a water tank, a sealing cover is fixedly connected with the upper end of the air outlet, and a second connecting hole is formed in the sealing cover in an embedded mode. The sand mill is high in grinding efficiency and short in work time, the discharging and collecting of the finished products are facilitated, and the heat produced in the grinding process can be fully used.

Description

technical field [0001] The invention relates to the related technical field of chemical machinery, in particular to a sand mill for coating production which is convenient for discharging. Background technique [0002] Paint is a chemical substance that is applied on the surface of objects to protect and decorate objects. According to different uses, paint is divided into many types and colors. In the process of paint production, before chemical reaction and mixing, it is necessary to The raw materials of coatings are crushed to make the particle size meet the required size. Therefore, corresponding sanders are needed to grind the raw materials. However, the existing sand mills for coating production on the market today still have certain defects, such as: [0003] 1. When grinding paint raw materials, the friction between the grinding body and the cylinder is used to break the raw materials into smaller particles, but the Chinese invention with the application number CN20181...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a kind of sand mill for the production of paint that is convenient to discharge, to solve the efficiency that most of the sand mills for paint production proposed in the above-mentioned background technology are relatively low in grinding efficiency, and there is no friction generated in the grinding process. Heat treatment, and the problem of inconvenient discharge and collection of finished products
