Building paint powder grinding and screening device

Abstract

The invention discloses a building paint powder grinding and screening device. The building paint powder grinding and screening device comprises a base, a grinding box, a grinding motor, a rotating grinding disc, a fixed grinding disc, a first sieve plate and a second sieve plate, wherein the rotating grinding disc is fixedly connected to the lower end of a main shaft, a plurality of groups of grinding bulges are arranged on the lower surface of the rotating grinding disc, the fixed grinding disc is fixedly installed on a bracket, a half gear is installed on an output shaft of a driving motorin an interference fit mode, and a rack is fixedly installed on the outer wall of the left side of the grinding box. According to the building paint powder grinding and screening device, the rotatinggrinding disc which rotates at high speed is matched with the grinding bulges, so that compared with a common grinding mode, powder particles are fine after grinding; additionally, the grinding box slides from left to right, so that the screening efficiency is greatly improved; secondary screening can be performed by the device, so that the building powder granularity is guaranteed after screening; and for building paint with low granularity requirements, primary screening can be switched, and the effects of simplicity and easiness in operation are achieved.

Description

technical field [0001] The invention relates to the field of paint processing, in particular to a grinding and screening device for architectural paint powder. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Additives, viscous liquids prepared with organic solvents or water. Coatings can be coated on the surface of objects by different construction techniques to form a continuous solid film with strong adhesion and certain strength. Coating ingredients usually need to grind various raw materials into powder before production. Usually, this process is completed by existing ball mills or grinding equipment, but the existing grinding equipment has poor grinding effect and cannot realize secondary screening and primary screening. switch....
