Coating sand mill for producing environment-friendly and low-carbon coating

Abstract

The invention discloses a coating sand mill for producing an environment-friendly and low-carbon coating. The coating sand mill comprises a base and a milling barrel. An installation support is connected with one side of the base and provided with the milling barrel. The milling barrel is provided with a feed inlet, a discharge outlet and a cooling sleeve. Milling beads, a rotating shaft and a screen net are arranged in an inner cavity of the milling barrel. The screen net blocks the inner side of the discharge outlet. A belt wheel is connected with the inner end of the rotating shaft and connected with a driving device. The rotating shaft is provided with milling discs. A centrifugal wheel is arranged at the outer end of the rotating shaft. The inner end of the centrifugal wheel is fixedly connected with the rotating shaft. A cylinder is arranged at the outer end of the centrifugal wheel. Engraved holes are evenly formed in the side wall of the cylinder. The outer end of the centrifugal wheel blocks the inner side of the screen net. The coating sand mill has the advantages that the milling beads can be prevented from blocking the screen net in the working process, and milling efficiency can be greatly improved.

Description

Technical field [0001] The invention relates to a paint sand mill for producing environment-friendly low-carbon paint. Background technique [0002] Paint sand mill is a processing equipment that stirs and grinds materials in the paint production process. The paint sand mill currently in use includes a grinding cylinder with a feed inlet and a discharge port. A cooling jacket is provided on the outside of the grinding cylinder. The cooling jacket is provided with a water inlet and a water outlet. The body is provided with grinding beads, a rotating shaft, and a screen. One end of the rotating shaft passes through the grinding cylinder and is connected with a motor through a mechanical transmission mechanism. A number of grinding discs are welded on the rotating shaft in the grinding cylinder. When working, the material is input into the grinding cylinder from the feed port, and the motor drives the shaft and grinding disc to rotate at high speed. The high-speed rotating grinding...

AI Technical Summary

Problems solved by technology

The above-mentioned coating sand mill has the following disadvantages during use: the grinding beads will flow to the screen along with the material, and then accumulate on the screen, eventually blocking the screen holes and reducing the flow of the material from the discharge port; at the same time, This part of the grinding beads accumulated on the screen cannot perform the grinding function, thus reducing the grinding efficiency
