Overview of Thickening Bucket

The thickener, also known as a cone classifier, is a simple equipment for classification, desliming, and concentration. The shape of the dense bucket is an inverted cone. Set a feeding cylinder at the center of the liquid level, with the bottom edge of the cylinder sinking several depths below the liquid level. The slurry is fed into the central cylinder in a tangential direction, buffered, and then flows out from the bottom edge. The outflow of ore slurry flows radially towards the surrounding overflow weir. During this process, coarse particles with a settling velocity greater than the rising velocity of the liquid flow will settle in the tank and be discharged through bottom settling sand. Fine particles enter the overflow tank along with the surface slurry. The feeding particle size is generally less than 2mm. The grading granularity is 75μ M or finer. 浓密斗(图1)

The dense hopper equipment has the advantages of simple structure, easy manufacturing, and no power consumption. Due to the large volume of the dewatering thickener cone, it also has a storage role in the production process. At present, the dewatering thickener equipment is mainly used in front of the hydraulic classifier to remove mud from the raw ore, in order to improve the classification efficiency; And it is also installed in front of the grinding equipment for ore concentration and dehydration to increase the feed concentration of the grinding machine; The dewatering thickener equipment is also used to control the feed concentration and ore volume before various slime sorting equipment.
