Embodiment Construction

[0084] 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.

[0085] After research, the inventor found that in the prior art, when controlling the feeding volume of the grinding bin, at each moment of detecting the actual feeding volume, the actual loading volume will be compared with the controlled feeding volume. If the two are not equal, it will be The vibration frequency of the vibration feeder will be adjusted with a fi...

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...
