The basic principle of thermal regeneration of coated sand is to use old sand pretreatment and boiling type thermal regeneration furnace equipment. First of all, the old sand is broken by vibration and magnetic separation, and then roasted in the boiling regenerative furnace. After sand production, it can be reused by heat preservation, cooling and screening.
The performance of the recycled sand after thermal regeneration is less than 0.3%, the particle size concentration rate is 80%-90%, and the gas generation rate is less than 3mL /g
Boiling resin sand thermal regeneration device:
The wide application of cold core, hot core, shell core and resin sand composite core technology has greatly improved the dimensional accuracy, surface quality and yield of castings, but how to recycle the old sand which is difficult to be recycled by these mechanical methods has been concerned by colleagues in the industry. Construction in shandong province in recent years, our institute, shandong university relevant scientific research personnel cooperation, jointly developed a boiling type resin sand thermal reclamation device, using manufacturer will these industrial waste, waste saves the casting manufacturing costs, and solve the environment pollution from waste sand, at the same time improve the quality of the castings, received a significant social and economic benefits.
