High temperature coated sand: The sand coated sand generally refers to thermal intensity, long time resistant, high temperature deformation, rather than its high refractoriness. It is through a special process recipe technology (usually when a certain amount of inert materials such as silica sand coated sand milling, high chromium ore, carbonaceous material or other inert materials, etc.), to produce a superior high temperature performance and integrated casting The new coated sand properties. High temperature, high strength, low inflation, low gas, gas, etc. slow hair. Especially for complex thin-walled precision iron castings (such as automobile engine block, cylinder head, etc.) as well as the high demand of castings (such as container train horn and brakes buffer housing, etc.) production of coated sand recycling machinery, may effectively eliminate sticky sand, deformation, thermal cracking and porosity and other casting defects regeneration and quality control of coated sand with human environmental requirements continue to increase renewable coated sand production line, recovery and regeneration of coated sand is becoming increasingly 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) and the gap between the slow rotation of the rotary frame (5-10mm) of the old sand friction to achieve the removal of resin and sand surface for the purpose of shaping sand, dust generated by processing through the ventilation dust coated sand recycling machinery, Qingdao Heng (certified), coated sand regeneration provided by Heng Machinery Co., Ltd.
