It can play a wear-resistant role and protect the bellows from media erosion. The deep cone thickener flow tube is a very important solid-liquid separation equipment in today's mineral processing plants. It is widely used in mining, mineral processing, metallurgy, chemical industry, alumina, environmental protection and water treatment industries, among which the application in mines is particularly important. The flow tube of the deep cone thickener has the advantages of high underflow concentration, large processing capacity, stable underflow concentration, and small footprint.
