Coated sand recycling the majority of experts has been a topic of concern, the current coated sand regeneration equipment is expensive and regeneration efficiency is not high, productivity is 5 tons / hour of thermal regeneration equipment prices in the 1200-1600 yuan, regeneration Cover membrane sand cost 65-90 yuan / ton, so the high cost of domestic foundry enterprises can not generally accepted. So the development of economic and efficient coated sand recycling equipment has a broad market prospect making entity core theory, coated sand can produce almost all types, especially high-precision casting core entity. When using the wet coated sand, direct access to hot-box equipment and tooling coated sand core making wholesale regeneration, without having the original equipment and tooling to make any changes. When using dry coated sand coated sand, because of its good liquidity coated sand regeneration manufacturers need to exhaust the way the core box, the nozzle and the core box seals for special treatment. Angle of repose principle can be used (coated sand repose angle of about 30o), coated sand into the sand shot resolved when the exhaust chamber and shoot do not shoot automatically when the sand coated sand whereabouts and other issues. Currently, the use of dry heat coated sand box core technology manufacturers are more coated sand coated sand _ _ regeneration process provided by Qingdao Heng Heng Machinery Co., Ltd. Qingdao.
