Description

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

technical field

The utility model relates to a mineral sorting device, in particular to a rotating belt-strengthened fine-grained material sorting device according to density.

Background technique

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.

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. The narrow-pitch inclined plate separator allows a 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.

3. When the belt transmission mechanism rotates, its upper surface has a disturbing effect on the heavy particle sedimentation layer, which promotes the loosening of the sedimentation layer. At the same time, the downward movement of the upper surface increases the water flow velocity gradient on the belt surface, resulting in a high lifting force, making The particles with small density and large particle size that originally settled on the surface of the inclined plate are suspended again, and finally enter the overflow to become products, improving the separation effect of the device;

4. Using the belt transmission mechanism, according to the change of the properties of the sorting materials and the actual sorting requirements, the belt rotation speed can be adjusted to obtain different sorting effects;
