Problems solved by technology
Although not desliming before selection can simplify the process, it will affect the separation accuracy. The high moisture content of the slime product will affect the product quality, resulting in a large load on the slime water treatment system, a large amount of slime in the slime system, and the cost of chemicals and electricity used. Larger; moreover, the selected coal slime without desliming passes through the dilute medium section and the combined medium section to discharge the medium system, the load of the magnetic separator is large, and the medium consumption increases

The invention discloses desliming equipment and a desliming process. The desliming equipment comprises an air distribution box, a dust collection funnel, and a dust removing device, wherein the air distribution box communicates with a first fan, and a box opening of the air distribution box communicates with a first dust collection opening located at a feeding end of a chute; the dust collection funnel comprises an inlet end and an outlet end, and the inlet end is opposite to the box opening and is used for collecting materials released by the box opening; and the dust removing device communicates with a second fan; and a second dust collecting opening located at a discharge end of the chute and the outlet end both communicate with the dust removing device, and the dust removing device isused for realizing coal and slime dust separation. The desliming equipment and the desliming process can effectively remove coal slime, simplify the process, improve the separation precision and reduce coal slime treatment capacity of a coal slime dewatering system.
Description
technical field [0001] The invention relates to the technical field of coal development, and more specifically, to a desliming equipment and a desliming process. Background technique [0002] In the process of coal production, it is inevitable to produce a large amount of materials with a particle size of less than 0.5mm. For coal preparation plants, this part of the materials is called coal slime. At present, the coal preparation plant uses a dense medium cyclone for separation treatment of coal slime, and separates the deslimed or non-deslimed selected. [0003] For dense medium separation, the desliming and non-desliming selections have one thing in common, that is, a large amount of coal slime all enters the coal slime water treatment system, and finally dehydrates through a filter or a filter press. Desliming selection has the advantage of lower separation limit. For example, 1.5mm or 0.5mm is mainly used for wet desliming, and the deslimed coal directly enters the sli...
