Problems solved by technology

[0003] In order to overcome the different thickness of ore particles in the pulp, the fine ore particles will also enter the ball mill for grinding, so the grinding speed of the pulp is slow and the efficiency is relatively low, and the use of machines such as centrifugal settlers and centrifugal filters consumes a lot of energy. The shortcoming of electric power, therefore, the technical problem of the present invention is: provide a kind of ore slurry that can be screened by hydrocyclone, save electric power, make fine-grained ore not need to carry out ball mill, reduce the amount of grinding ore, improve ball mill Slurry coarse particle screening and grinding device with high effective grinding efficiency

Abstract

The invention relates to a screening and grinding device, in particular to an ore pulp coarse particle screening and grinding device. Therefore, the technical problem of the invention is that the orepulp is screened through the hydrocyclone, the electric power is saved, the ore of the fine particles does not need to be subjected to ball milling, the ore feeding amount is reduced, the ore pulp coarse particle screening and grinding device with the effective grinding efficiency of the ball mill is improved, according to the technical scheme, the ore pulp coarse particle screening and grinding device comprises a base, an ore pulp pump, a feeding pipe, a discharging pipe, a support and the like, wherein the ore pulp pump is arranged on the left side of the top of the base. The ore pulp is pumped into the box body through the ore pulp pump, the height difference between the box body and the hydrocyclone is large, so that after the ore pulp is discharged into the hydrocyclone, the hydrocyclone can be driven to work, so that ore particles smaller than 3 mm can be separated from ore particles larger than 3 mm, so that the ore particles smaller than 3 mm do not need to be subjected to ballmilling, the ore grinding amount is reduced, and the effective grinding efficiency of the ball mill is improved.

Description

technical field [0001] The invention relates to a screening and grinding device, in particular to a screening and grinding device for coarse particles of ore pulp. Background technique [0002] When grinding the pulp ore particles, they usually enter the ball mill directly for grinding. Because the ore particles in the pulp are of different thicknesses, the fine ore particles will also enter the ball mill for grinding, so the grinding speed of the pulp is relatively slow. , The efficiency is relatively low. At present, the ore particles in the slurry are generally separated by machines such as centrifugal settlers and centrifugal filters. The use of machines such as centrifugal settlers and centrifugal filters consumes a lot of power and cannot save energy well. Contents of the invention [0003] In order to overcome the different thickness of ore particles in the pulp, the fine ore particles will also enter the ball mill for grinding, so the grinding speed of the pulp is ...
