The invention discloses a coarse coal slime sorting equipment based on centrifugal force field strengthening, which comprises a feeding pipe and a rotating drum with a hollow inside. The upper port of the casing is inserted into the drum, and a slurry distribution plate is installed under the nozzle. The slurry distribution plate is installed in the drum. When the drum rotates, the slurry distribution plate is driven to rotate. Funnel, the upper opening of the receiving funnel is a ring cutter, the outlet of the funnel at the bottom of the receiving funnel is connected to the clean coal discharge pipe, the clean coal discharge pipe extends from the bottom of the drum, and the area between the clean coal discharge pipe and the rotating drum It is the discharge area at the bottom of the drum. The discharge area at the bottom of the drum is connected with an opening at one end of the tailing coal discharge pipe, and the other end of the tailings discharge pipe is opened from the side wall of the casing. The beneficial effect of the invention is to realize the separation of concentrate and tailings, and the separation efficiency is high.
Description
technical field [0001] The invention belongs to the technical field of coal slime separation, and relates to coarse coal slime separation equipment based on centrifugal force field strengthening. Background technique [0002] In recent years, with the improvement of coal mining mechanization, the content of fine-grained coal in raw coal is getting higher and higher. However, it is difficult for conventional gravity separation and flotation equipment in my country to obtain satisfactory separation results for coarse coal slime. Because the accuracy of gravity separation becomes worse with the decrease of particle size, and the flotation operation will easily cause the loss of low ash clean coal with the increase of particle size. However, the coarse coal slime is not sorted or sorted but its effect is poor, resulting in waste of resources. Therefore, the effective separation of coarse coal slime has received widespread attention in my country's coal preparation industry in re...
