Resin sand is resin as a adhesive configuration type (core) sand, old sand regeneration is to maximize the removal of the sand particle surface adhesive film, adjust the surface of the sand particles (particle size), it is very economical to replace the new sand. Old sand regeneration four-use, can save new sand consumption and the transportation costs required to throw old sand, and so on, and the regeneration of sand grain uniform. The surface is smooth and the heat is fixed. It is beneficial to improve the quality of castings, especially when resins are recycled and reused, the amount of resin addition can be reduced. Reduces the cost of resin. It also reduces environmental pollution caused by the discharge of waste sand.
