Embodiment Construction

[0064] 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.

[0065] The inventor found through research that the reason why the existing technology cannot eliminate the problem of large ore hindering the feeding is that the existing technology adopts the vibration frequency set for the vibration feeder of each grinding bin, which is only based on the actual situation. Determined by quantity. In fact, if the vibration freque...

Abstract

The invention discloses a method and device for controlling feeding blocking of an ore grinding chamber in the ore grinding process. The method comprises the steps that the controlled standard vibration frequency of current feeding is determined according to the current actual feeding quantity in the ore grinding process; whether the actual feeding quantity and the standard vibration frequency in the last abnormal judging period satisfy the feeding blocking condition or not is judged, if the answer is positive, a current adjusting coefficient of each ore grinding chamber is increased according to a preset correcting value and the current adjusting coefficient of each ore grinding chamber is determined again, and if the answer is negative, the current adjusting coefficient of each ore grinding chamber remains unchanged; the arithmetic product of the current adjusting coefficient of each ore grinding chamber and the standard vibration frequency is determined to serve as the target vibrating frequency of a vibrating ore feeder of each ore grinding chamber. According to the technical scheme, the actual feeding quantity can be rapidly adjusted to the control feeding quantity, so that the feeding quantity of each ore grinding chamber is even and accurate and granularity of ground ore is indirectly made to be stable.

Description

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