Description

Technical Field

[0001] The utility model relates to the technical field of oily paint raw material processing, in particular to an oily paint raw material grinding device. Background Art

[0002] Oil-based paint is a type of paint that uses drying oil as the main film-forming substance. During the production process, the pigment and paint must be mixed. After mixing, the pigment lumps and the condensed air bubbles contained in the pigment itself must be torn apart and discharged using grinding equipment, and the larger powder particles must be ground into the specified fineness before subsequent production and use can be carried out.

[0004] When the device is in use, the oily paint raw material will pass through the first hole and the second hole on the fixed plate, slide down to between the fixed plate and the grinding plate, and then be ground by the rotating grinding plate. However, the second hole on the fixed plate is relatively small. If the oily paint raw material to be ground is relatively large in particles, it cannot pass through the second hole on the fixed plate. This results in that, on the one hand, the oily paint raw material with larger particles cannot reach between the fixed plate and the grinding plate for grinding, and on the other hand, the oily paint raw material with larger particles will block the second hole on the fixed plate, affecting the grinding use of the entire device.
