Embodiment Construction

[0089] 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.

[0090] The inventor has found through research that for a long time, the control of the grinding machine in the prior art is based on the main influencing factor of the load of the grinding machine, which is the feeding amount of the grinding machine (that is, the amount of mineral material put into the grinding machine Quantity) Considering this point, the control...

Abstract

The invention discloses a method and a device for adjusting ball filling rate in ore mill control. The method includes: acquiring current milling sound status, spindle oil pressure and power of an ore mill, and determining current milling sound status, oil pressure status and power status of the ore mill; in response to the current high load status of the ore mill, reducing the feeding capacity of the ore mill; in response to the current low load status of the ore mill, increasing the feeding capacity of the ore mill; in response to the ore mill being simultaneously in current reasonable milling sound status, low oil pressure status and high power status, increasing ball filling rate of the ore mill; in response to the ore mill being simultaneously in current reasonable milling sound status, high oil pressure status and low power status, decreasing the ball filling rate of the ore mill. The method and the device have the advantages that the ball filling rate can be increased when balls in the ore mill are few, the ball filling rate can be decreased when the balls in the ore mill are many, and accordingly production efficiency of the ore mill can be improved.

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...
