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) 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 coated sand recycling equipment manufacturers, the dust generated by the processing of iron dust ventilation with Sand technology was developed first in the small foundry business and successful application. The late 1970s, China's first iron built with Sand casting production lines. 80 years after the supply of coated sand recycling equipment, type of iron coated sand casting process of basic and applied research teams have been formed enterprise coated sand recycling equipment manufacturing, and has been developing rapidly. Currently coated sand regeneration, China has hundreds of companies with Sand cast iron used in production, with an annual output of iron with Sand casting about 100,000 tons (mainly crankshafts, camshafts, gears and export castings, etc.), year consumption of approximately 20,000 tons of coated sand.
