Method and device for adjusting steel ball filling rate in control of ore grinding machine

Abstract

The application discloses a method and device for adjusting the steel ball filling rate in control of an ore grinding machine. The method comprises the following steps: obtaining a current grinding sound status value, a current main shaft oil pressure and a current grinding machine power of the ore grinding machine, calculating a load parameter of the grinding machine according to the grinding sound status value and the grinding machine power; determining a current oil pressure status and a current load parameter status of the ore grinding machine according to an oil pressure value range to which the main shaft oil pressure belongs and a load value range to which the grinding machine load parameter belongs; when the ore grinding machine is in a high-load status currently, reducing the ore feeding quantity; when the ore grinding machine is in a low-load status currently, increasing the ore feeding quantity; when the ore grinding machine is simultaneously in high-oil pressure status and a low-load parameter status currently, reducing the steel ball filling rate; when the ore grinding machine is simultaneously in low-oil pressure status and a high-load parameter status currently, increasing the steel ball filling rate. According to the technical scheme of the application, the steel ball filling rate can be increased when steel balls of the ore grinding machine are less, and can be reduced when the steel balls of the ore grinding machine are more, so that the production efficiency of the ore grinding machine is increased.

Description

technical field [0001] The application relates to the field of ore smelting control, in particular to a method and device for adjusting the filling rate of steel balls in the control of ore grinding machines. 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 dissocia...
