A rotating belt reinforced fine-grained material sorting device according to density

Abstract

A rotating belt strengthening fine material sorting device according to density comprises a PID control instrument, an overflow collecting groove and a sorting column; the sorting column comprises an inclined groove chamber and a vertical groove chamber; a plurality of belt transmission mechanisms consistent with the inclination direction of the inclined groove chamber are arranged in the inclined groove chamber and each comprise an annular belt, a belt wheel and a carrier roller, and each belt wheel and each carrier roller are correspondingly supported at the two ends of the corresponding annular belt; the bottom of the inclined groove chamber is closely connected with the top of the vertical groove chamber; the overflow collecting groove is formed in the top of the inclined groove chamber; a feeding port is formed in one side of the vertical groove chamber; an inverted-cone-shaped flow distributing plate is arranged at the bottom of the vertical groove chamber; a water inlet pipe is arranged below the inverted-cone-shaped flow distributing plate; and a bottom flow discharging port is formed in the center of the inverted-cone-shaped flow distributing plate and connected with the PID control instrument. The rotating belt strengthening fine material sorting device according to the density greatly accelerates the movement of material sorting, the handling capacity is improved, a higher shearing rate is provided for sorting, larger elevating force is generated, the influences of the particle granularity effect in traditional material sorting are overcome, and the density sorting effect is improved.

Description

technical field [0001] The invention relates to a mineral sorting device, in particular to a rotating belt reinforced fine-grained material sorting device according to density. Background technique [0002] With the enlargement of gravity separation equipment, the lower limit of separation continues to increase, while in flotation, the coarse particles are easy to fall off from the air bubbles, resulting in a low upper limit of flotation, so that the fine particle minerals between gravity separation and flotation cannot be effectively separated . Therefore, the efficient separation of fine-grained minerals has become the focus and hotspot of research at home and abroad, especially the separation of fine-grained coal. [0003] Gravity separation of materials by density has become the most popular method because of its low cost, but the lower limit of separation is low for fine-grained materials because the particle settling velocity is greatly affected by particle size.

[0003] Gravity separation of materials by density has become the most popular method due to its low cost, but the lower limit of separation is low for fine-grained materials because the particle settling velocity is greatly affected by particle size

The narrow-pitch inclined plate separator allows greater rising water velocity in the inclined channel, which increases the processing capacity of the equipment and becomes an important equipment for the separation of fine-grained materials, but it still needs to be improved in terms of improving the separation effect.
