Clay sand is a type (core) sand with clay as binder. Mechanization of sand treatment is an important part of foundry production. The preparation of core sand directly affects the quality of casting production, the increase of production and the reduction of cost. Because of the complexity of sand treatment process, the workload of clay sand treatment and transportation is very large, and the environment is very harsh, so the mechanization of sand treatment process is an important part of foundry production. The main task of the Sand Treatment Department is to provide qualified molding sand and core sand for the molding core Department.
