Embodiment Construction

[0081] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0082] The inventor has found through research that for a long time, the load control of the grinding machine in the prior art is based on the main influencing factor of the grinding machine load, which is the feeding amount of the grinding machine (that is, the amount of ore put into the grinding machine). The amount of material) is considered and realized through...

Abstract

The invention discloses a method and a device for controlling feeding concentration of an ore grinder. The method comprises the following steps of obtaining a current sound grinding state value of the ore grinder, an oil pressure of a main shaft and an ore grinder power, and calculating a load parameter of the ore grinder according to the current sound grinding state value and the ore grinder power; determining the current oil pressure state and a load parameter state of the ore grinder according to an oil pressure numerical range of the oil pressure of the main shaft and a load numerical range of the ore grinder; reducing the feeding concentration of the ore grinder in response to a high oil pressure state and a high load parameter state that the ore grinder are simultaneously positioned currently; and increasing the feeding concentration of the ore grinder in response to a low oil pressure state and a low load parameter state that the ore grinder is simultaneously positioned currently. According to the technical scheme provided by the invention, when the load state of the ore grinder is high, the feeding concentration is reduced, the load of the ore grinder is reduced, and a mine material is fully smashed; when the load state of the ore grinder is low, the feeding concentration is improved, the efficiency of an ore grinding process is improved, and the energy consumption of the unit ton finished ore is reduced.

Description

technical field [0001] The present application relates to the field of mineral processing process control, in particular to a method and device for controlling the ore concentration of an ore mill. Background technique [0002] In the production process of ore smelting, since the raw ore obtained from mining cannot meet the smelting requirements, it is necessary to process the raw ore first to obtain concentrates that meet the smelting requirements, and then use them in the smelting process. The beneficiation operation mainly includes crushing and screening of raw ore, grinding and grading, sorting, concentrate dehydration and other links. Among them, the grinding process is to crush the crushed ore to a suitable particle size, and provide the crushed minerals to the sorting process. During the grinding process, since the ore is crushed, the effective mineral components can be dissociated from the gangue, and different effective mineral components can be dissociated from ea...
