Adjustable grinding process

Abstract

The invention discloses an adjustable grinding device, comprising: a first ball mill and a second ball mill; a first cyclone, a second cyclone, a third cyclone and a fourth cyclone flow device; a first slurry pump, a second slurry pump, a third slurry pump, a fourth slurry pump, a fifth slurry pump and a sixth slurry pump; a first pump pool and a second pump pool. The adjustable ore grinding device of the present invention has the following advantages: it can flexibly realize the direct switching between two series of one-stage grinding and a series of two-stage grinding processes, meet the process requirements, and improve productivity. When the ball mill fails or is overhauled, in order to avoid production stoppage, one of the series of one-stage grinding and two closed-circuit classification grinding processes can be realized. The device has strong adaptability to ore, and during the ore mining process, the properties of the ore are changeable, so it can better adapt to the ore with changeable properties.

Description

technical field [0001] The present invention relates to a mining machine, more precisely, an adjustable grinding process. Background technique [0002] Grinding is the follow-up operation of the crushing operation, and also belongs to the preparatory operation before sorting. Grinding operations are very important in ore sorting. This is because most of the useful minerals and gangue are often closely linked together, and must be broken 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 the concentrator generally adopts a one-stage grinding or two-stage grinding process. If the operating fineness is required to be less than 70%, a one-stage grinding process is generally used, and a two-stage grinding process is generally used when th...

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
