High rate thickener operation manual

In the 1970s and 1980s, machines known as High Capacity or High Rate Thickeners were introduced in the mining industry. The distinguish feature of these equipment was that the feed was injected into the sediment bed. EIMCO HI-CAP Thickener (Webpage)High Capacity Thickeners. Enviro-Clear High Capacity CT (Web page)

    High Rate Thickeners - Solid Liquid Separation

    Description. The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high-rate machines. Furthermore, they are normally positioned far away from the center of the plant so to allow

    Jun 02, 2017 Various operating points are shown in Figure 18 to illustrate concepts of operation of the thickener. Table 1 is a summary of the operating conditions at each of the points illustrated. For this example, the following relationships apply: Feed rate x unit area = 40 m . Underflow rate x underflow conc./1000 = feed rate
