Types of Thickeners

In general, thickener is applied to finish the work of concentrating and tailings dewatering before filtration. It also goes for the chemical industry, sewage treatment industry, and concentration and purification of solids. The thickener is mainly composed of two parts including thickening tank and rake-type mud scraper, and the tank is used to store the slurry while the scraper is used to deal with the settling materials. Thickening equipment developed lately in China. The first thickener was born in Shenyang Mining Machinery CO., LTD, which made in accordance with Soviet-style thickener. With about a decade of exploration, a series of thickening products are produced in the mid-1960s., which met the needs of the middle and small scale dressing plants in domestic basically. By the 1970s, thickening equipment was in the trend of systematization and standardization, and the classification became more complicated. As the policy of reform and opening up in the 1980s, lots of new technology and advanced equipment were introduced into China, which promoted the rapid development of the thickening in China. Then various specifications and models of thickeners were produced, and the technology has become increasingly advanced, such as the large-scale thickener with φ100m,the automatic rake type peripheral transmission thickener, high-efficiency thickener, deep cone thickener and so on. These thickeners are all the representatives of Xinhai, they have the superior quality and competitive price, and they can meet the customers needs.

Thickeners can be classified on the basis of the way of transmission, which includes center transmission thickener and peripheral transmission thickener. The latter one also can be classified into running roller transmission and rack transmission thickener. Recently, in many factories, the center-feeding way has been replaced by the peripheral-feeding way and bottom-feeding way. And this change could increase the capacity of the thickener, effectively reduce the solid content of the overflow, improve the concentration of the settling sand, improve the shape and structure of the thickener, so that the conical structure can increase the speed of settling dramatically and enlarge the capacity. The types of the thickener is becoming more and more perfect in domestic.
