Dahan manufacturers is a fine powder screening machinery factory. With the development of market economy and technology, product quality and fineness of various powder materials, precision increasingly demanding. Fine powder material easy to adhere to, small size, light weight, easy suspension characteristics; existing domestic vibration sieve, sieve using its gravitational potential linear exciting force, elastic work hard to screening, it can lead dust, and more difficult to meet the technical requirements. Han's response to this situation, engineers and technicians trial after years of research, developed specifically for fine powder screening of the latest products - air sieve.
80-530 mesh sieve with a network of various powder materials screening classification, its high screening efficiency, large output, automatic feed nesting, continuous operation, no pollution, making it difficult in the past with a variety of high-shaker fine degree of precision screening operations become easy. After light calcium on 120-180 mesh, 300 mesh TSP, 400 mesh active calcium, hawthorn 300 mesh powder, zinc powder 320-500 mesh, 500 mesh black iron oxide, iron oxide red, 120-160 mesh in powder, 180- sieved using a 270 mesh quartz powder materials, the measured output per hour per square meter screen area were about a ton, while the measured screening efficiency above 95%, air dust content of less than 10mg / m3.
