Crude coal slime separating water medium fluidized bed apparatus

Abstract

The crude coal slime separating water medium fluidized bed apparatus as mineral slime separating apparatus is provided with a feeding pipe in the upper part, a feeding box possessing inside stirrer, a material pipeline connected between the feeding pipe and the feeding box, a outside overflow trough possessing refined mineral outlet, a sieve plate connected to the underflow port in the lower part, and a water pipeline connected between the water pump and the water inlet of the separating apparatus. By means of the upward water flow and the downward coal slime material in different speeds, the present invention generates self separating medium to complete the separation of coal mineral from the coal gangue in the different density. The present invention has the features of small size, low power consumption, high separating effect, etc.

Description

technical field [0001] The invention belongs to slime sorting equipment, and mainly relates to a coarse coal slime sorting device. Background technique [0002] Jigs, dense medium splitters, flotation machines, spiral separators, shakers, etc. are currently the most commonly used equipment for sorting coarse coal slime, and the effective separation range of jigs is coarse coal larger than 0.5 mm Slime particles, fine coal slime less than 0.5 mm cannot be effectively sorted, poor adaptability, and narrow application range; when the dense medium splitter separates finer coal slime, it needs to increase the feeding pressure, which leads to energy consumption The size of the equipment increases, and the equipment wears seriously; the flotation machine has a good separation effect for the separation of coal slime smaller than 0.5 mm, but the separation effect is poor for the separation of coal slime larger than 0.5 mm, and it needs to add chemicals during the sorting operation ,...

[0002] Jigs, dense medium splitters, flotation machines, spiral separators, shakers, etc. are currently the most commonly used equipment for sorting coarse coal slime, and the effective separation range of jigs is coarse coal larger than 0.5 mm Slime particles, fine coal slime less than 0.5 mm cannot be effectively sorted, poor adaptability, and narrow application range; when the dense medium splitter separates finer coal slime, it needs to increase the feeding pressure, which leads to energy consumption The size of the equipment increases, and the equipment wears seriously; the flotation machine has a good separation effect for the separation of coal slime smaller than 0.5 mm, but the separation effect is poor for the separation of coal slime larger than 0.5 mm, and it needs to add chemicals during the sorting operation , which increases the cost of separation; the height of the screw separator is large, the floor space is large, and the installation is inconvenient. The medium ore for feeding and circulation needs sand pumping, and the concentration and amount of ore pulp have a great impact on the quality of product separation; shaking There are many operating factors of the bed, it is difficult to control, and the quality of coal slime separation is not easy to guarantee
