A method and device for controlling the blockage of feeding in the grinding bin during the grinding process

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...

Problems solved by technology

[0006] The technical problem to be solved by the embodiments of the present application is to provide a method and device for controlling the feeding of the grinding bin during the grinding process, so as to solve the problem of adjusting the vibration according to the current actual feeding amount of the grinding bin in the prior art. The vibration frequency of the feeder causes the technical problems of uneven and inaccurate feeding of the grinding bin and unstable particle size of the grinding product when the feeding is blocked.
