Clay sand is the molding sand or core sand which is made of the clay as the binder.
Clay sand is composed of raw sand (used sand and new sand); clay binder; water; coal powder; etc.
Raw sand is composed of used sand and new sand.
The role of water is to wet the clay and make the clay produce cohesion.
The addition of coal powder is to prevent the casting from sticking sand and reduce the roughness of the casting surface.
According to the layout of the foundry workshop, process requirements and matching different molding forms, the clay sand production line can have a variety of changes, but the process generally includes: Used sand recycle (shakeout and magnetic separation); Used sand crushing; Used sand sieving; Used sand cooling; Used sand regenerating; Dust removal; Clay and coal powder transportation, New and used sand transportation, and molding sand mixing.
