Method and device for adjusting vibration frequency of ore feeder in ore grinding process

Abstract

The embodiment of the invention discloses a method and device for adjusting the vibration frequency of an ore feeder in the ore grinding process. The method comprises the steps that according to the actual feeding quantity which is detected and stored in advance, the deviation ratio that the current feeding quantity deviates from the control feeding quantity is calculated; according to the numerical range of the deviation ratio, a current constraint period corresponding to the deviation ratio is determined; whether time lasting from the moment when the current vibration frequency of the ore feeder is adjusted at the last time to the current moment is longer than the time of the current constraint period or not is judged, if the answer is positive, the current vibration frequency is adjusted according to the deviation ratio, and if the answer is negative, the current vibration frequency is not adjusted at the current moment. According to the technical scheme, excessive adjustment to the current vibration frequency can be avoided and the actual feeding quantity of an ore grinding chamber is prevented from being over adjusted and deviating from the control feeding quantity, so that accurate control over the feeding quantity of the ore grinding chamber is achieved and accurate control over granularity of ground ore is indirectly achieved.

Description

technical field [0001] The present application relates to the field of ore smelting, in particular to a method and device for adjusting the vibration frequency of an ore feeder during ore grinding. 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...
