The main selection of high-quality coated sand natural quartz sand as raw sand coated sand regeneration, thermoplastic phenolic resin, methenamine and enhancer for raw materials. Depending on the technology needs of users, the curing speed, stripping, mobility, collapsibility, the casting surface finish, storage and other aspects of appropriate adjustments to match. Is one of the cars, tractors, hydraulic parts and other materials the best shape. Coated sand regeneration and quality control as human beings continue to improve environmental protection requirements, coated sand recovery and regeneration becomes more and more important and urgent. The most commonly used method for mechanical recycling and renewable thermal regeneration. The basic principle is to use high-speed mechanical recycling back wheel wheel (about 3500r / min) gap (5-10mm) of the old sand regeneration friction coated sand production line between the slow rotation of the rotary frame and, in order to achieve the removal of the old resin sand surface and purpose of shaping sand, dust generated by processing through the ventilation dust coated sand recycling has been a topic of concern for the majority of experts, the current coated sand regeneration equipment is expensive and inefficient regeneration coated sand regeneration, productivity is 5 tons / hour of thermal regeneration equipment prices in the 1200-1600 yuan, coated sand regeneration cost 65-90 yuan / ton, so the cost can not be cast for domestic enterprises universally accepted. So the development of economic and efficient coated sand recycling equipment has a broad market prospect coated sand recycling equipment, Qingdao Heng (certified), coated sand regeneration provided by Heng Machinery Co., Ltd. Qingdao. Qingdao Heng Machinery Co., Ltd. (www.thjidian.com) is Qingdao, cleaning, cleaning equipment leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
