Embodiment Construction

[0067] 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.

[0068] The inventor found through research that the reason why some of the grinding bins are empty and the rest of the grinding bins still have mineral materials in the prior art is that the prior art uses vibration feeders for each grinding bin. The vibration frequency is the same. In fact, due to the uneven size of the mineral material and the inconsistent distr...

Abstract

The invention discloses a method and device for controlling discharging of multiple ore grinding bins in an ore grinding process. The method comprises the steps: determining a fundamental vibrating frequency of current controlled discharging according to the current actual discharging amount in the ore grinding process; detecting an actual material level of each ore grinding bin, and calculating a frequency regulating coefficient of each ore grinding bin according to the actual material level of each ore grinding bin, wherein the lower the actual material level of the ore grinding bin is, the smaller the frequency regulating coefficient is; determining a product of the frequency regulating coefficient of each ore grinding bin and the fundamental vibrating frequency as a target vibrating frequency of a vibrating ore feeder of each ore grinding bin. According to the technical scheme of the invention, the condition of emptying of the ore grinding bin in a discharging process can be effectively avoided, the probability of ore-free operation of the vibrating ore feeder is reduced, and thus the condition that the actual discharging amount greatly deviates from the controlled discharging amount instantly due to emptying of the ore grinding bin is reduced so that the discharging amount of the ore grinding is uniform and accurate, and the granularity of ore ground products is stable.

Description

technical field [0001] The present application relates to the field of ore smelting, in particular to a method and device for controlling feeding of multiple grinding bins during the ore grinding process. 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 ...
