Kinetics of Mechanical Floccule Synaeresis

摘要

The authors analyze the kinetics of water removal from the orthokinetically formed floccules by mechanical synaeresis. The floccule moisture and time relationship is established under influence of unbalanced force system. It is found that the mechanical treatment of floccules in coal flotation concentrate at velocity gradient of 3-301/s reduces the product moisture by 1.5-2.0%, and the floccules integrity remains undisturbed. This finding allows reducing the concentrate drying cost by 10-15%.
