Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a dust removal device for grinding. Background Art

[0002] Grinding is a type of surface modification technology, which generally refers to a processing method that uses rough objects (such as sandpaper containing high hardness particles) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. During the grinding process, more dust is often generated. Dust and fine fragments can invade the liver, lungs, cardiovascular system and blood through the respiratory tract, causing harm to human health and affecting the working environment. Therefore, grinding and dust removal equipment is often used in the process of grinding steel plates.
