Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a sand mill. Background Art

[0002] With the increase of people's production needs, some scientific and technological products are also gradually increasing. Among them, the use under special environmental conditions is also beginning to be realized. For example, the coatings of some mechanical parts such as automobiles need to be quickly cured under specified conditions, so the use of light-curing coatings is the most appropriate way. After the paint is applied, the paint needs to be exposed to specified light to make the paint cure quickly, thereby increasing the demand for the use of such light-curing coatings.

[0003] The demand began to increase gradually, and the production of coatings also required a faster speed. During the existing production and grinding of raw materials for coatings, it was impossible to feed the raw materials while grinding. The grinding equipment with raw material feeding would squeeze the unground raw materials to the outlet too early, resulting in the problem of insufficient stability in the raw material grinding by the equipment.
