What is resin sand casting foundry plant

Resin bonded sand is a core sand with resin as binder. The regeneration of the old sand is to remove the binder film on the surface of the sand grains to the maximum extent, and to adjust the grain size of the sand grains so that it can be used economically instead of the new sand. The recycled sand can save the consumption of new sand and the transportation cost needed to discard the used sand. Moreover, the recycled sand has uniform surface, smooth surface and good thermal stability, which is beneficial to improving the quality of castings, especially when the resin sand is recycled, the invention can reduce the amount of resin addition, the cost of the resin sand and the environmental pollution caused by the discharged waste sand.

The structure of machine is made up of landing leg,chute,boiling board,upper cover,compound spring,bar sealed paneland so on.Operational theory: Crushed sand falls into vibrating boiling cooling bed from sand inlet. When it advances along the vibration direction,blower system brings cold air from the bottom of pore plate, wind blows up from boiling board, while dust cleaning fan pump the air from suction opening of suction hood, so sand forms boiling state on the above of boiling board,sand and hot sand fully contact let hot sand moisture take away. It discharges from suction opening. Hot sand can achieve the aim of cooling. When sand is boiling, sand is brought into sand outlet in the influence of exciting force of vibrating motor
