Adjustable ore grinding process

Abstract

The invention discloses an adjustable ore grinding device. The adjustable ore grinding device comprises a first ball grinder, a second ball grinder, a first cyclone, a second cyclone, a third cyclone, a fourth cyclone, a first slurry pump, a second slurry pump, a third slurry pump, a fourth slurry pump, a fifth slurry pump, a sixth slurry pump, a first pump pool and a second pump pool. The adjustable ore grinding device has the following beneficial effects that a two-series one-stage ore grinding process and a one-series two-stage ore grinding process can be flexibly and directly switched, process requirements can be met, and productivity can be improved. When the ball grinders break down or are maintained, in order to avoid halt production, the one-stage ore grinding two-time closed-loop classification ore grinding process of one series can be achieved. The adaptability of the device on ore is high, in the ore extraction process, the ore characteristics are changeable, and the device can adapt to the ore changeable in characteristic better.

Description

technical field [0001] The invention relates to a mining machine, more precisely, an adjustable ore grinding process. Background technique [0002] Grinding is the follow-up operation of crushing operation, and also belongs to the preparatory operation before sorting. Grinding is very important in ore sorting. This is because most useful minerals and gangues are often closely connected together, except for a few dissociated placer and some high-grade mineral resources in nature, which must be crushed and ground to make them Most of them are in a single state, so the grinding operation is an important part of the concentrator, and its work efficiency and product quality directly affect the technical and economic indicators of the concentrator. [0003] At present, the grinding operation of ore concentrator generally adopts one-stage grinding or two-stage grinding process. If the operation fineness is required to be less than 70%, the one-stage grinding process is generally...

AI Technical Summary

Problems solved by technology

[0004] If the nature of the ore feed is complex and the ore properties are unstable, the fineness of the operation is required to be about 70% at -200 mesh, just in the case of one-stage grinding or two-stage grinding. Simply use one-stage grinding or two-stage grinding Mining process may not be better suited to variable ore properties
