Thickeners (high-efficiency thickeners) are generally composed of the following parts: thickening tank, bun rack, transmission device, bun rack lifting device, feeding device, unloading device and signal safety device. The main feature of its work is to add a certain amount of flocculant to the slurry to be concentrated. The purpose is to make the ore particles in the slurry form flocs, which can speed up the sedimentation rate, thereby increasing the concentration rate and speeding up the concentration efficiency.
According to the structure of the thickener, it can be divided into central drive thickener, peripheral drive thickener, high-efficiency thickener, sludge thickener, intermittent thickener, peripheral drive thickener, sectional rake thickener, center rake thickener Thickener. Vertical flow and radial flow continuous thickeners.
