Coated sand recycling the majority of experts has been an issue of concern small resin sand reclamation line, now coated sand regeneration equipment is expensive and regeneration efficiency is not high, productivity is 5 tons / hour of thermal regeneration equipment prices in 1200-1600 ten thousand yuan renewable resin sand production line, recycled coated sand will cost 65-90 yuan / ton, so the cost can not be cast for domestic enterprises generally accepted. So the development of economic and efficient coated sand recycling equipment has a broad market prospect easy collapsibility coated sand: it is for non-ferrous metals (especially aluminum) is not easy to sand casting and developed a coated sand. The sand also has good strength has excellent low temperature collapsibility. With its production of non-ferrous metals (aluminum, copper alloys, etc.) castings, no need to re-heating the casting sand, just after pouring the casting to cool for 24 hours, you can SHAKERS. Centrifugal Casting coated sand: the coated sand suitable for centrifugal casting process, it can be used to replace the production of centrifugal casting and other coating materials based on iron pipe diameter size and technical requirements of different resin sand recycling equipment, can be processed into different performance centrifugal casting coated sand. Differs from other types of sand and resin-coated sand regeneration, is the large number of coated sand density, low-fat and fat volume of gas a slow vibration sand, high-strength, low gas, low expansion ; 2, lax, good casting surface finish; 3, can not afford to shell layer, good thermal stability, good thermal conductivity, good liquidity, casting surface smooth; 4, high strength, high temperature, low inflation, off mold, and anti-sticky sand is good; 5, even without shelling shell, fast curing; resin sand reclamation equipment manufacturers, Qingdao Heng (certified), Dongying resin sand regeneration provided by Heng Machinery Co., Ltd.
