Products with parameters

Brief introduction spiral classifier
Spiral classifier is widely used in mineral processing plant with ball mill with into closed cycle process by way of split mineral sand, or used in gravity concentrator to grade ore and fine mud, and metal ore dressing process of pulp particle size grading, and ore washing process in the removal of mud, dehydration and other operations. The machine has the advantages of simple structure, reliable work, convenient operation and so on.
Product Feature of spiral classifier
Spiral classifier has high weir single screw and twin screw, low weir type single screw and twin screw, sinking type single screw and double helix several classifier, low weir is used rarely, mainly high weir type and sunk and XL spiral classifier. The machine uses the base channel, the body adopts welded steel plate. Into the head of the screw shaft, the shaft head, using pig iron, durable, lifting devices of electric and manual two.
