A ceramic grinding wheel sand mixing device

Technical Field

The utility model relates to the technical field of grinding wheel production equipment, in particular to a ceramic grinding wheel sand mixing device.

Background Art

Grinding wheel is also called bonded abrasive. Grinding wheel is a bonded abrasive with a certain shape and strength made of ordinary abrasives bonded by a binder. It is generally composed of abrasives, binders and pores. These three parts are often called the three elements of bonded abrasives. In the production process of ceramic grinding wheels, a sand mixing device is needed to stir and mix the abrasives. The degree of mixing and stirring of the abrasives is one of the important factors that determine the quality of the grinding wheel. Most sand mixing devices only set a single axis or double axis in the sand mixing tank to stir the mixed sand.
