Embodiment Construction
[0058] 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.
[0059] After long-term research, the inventor found that the reason why the adjustment of the optimal ore feed rate of the grinding machine in the prior art is not timely and accurate is that the existing technology needs to rely on manual repeated times according to the performance of the load status of the grinding machine. To determine whether the optimal ore fe...

The invention discloses a method and device for obtaining an optimum ore feeding amount of ore mill. The method comprises the following steps: obtaining a current actual ore feeding amount deviation value and an oil pressure change value; comparing the actual ore feeding amount deviation value with a first threshold value and comparing the oil pressure change value with a second threshold vale; if the actual ore feeding amount deviation value is less than the first threshold value and the oil pressure change value is less than the second threshold value, increasing the current optimum ore feeding amount; if the actual ore feeding amount deviation value is larger than the first threshold value and the oil pressure change value is larger than the second threshold value, decreasing the current optimum ore feeding amount. Through the technical scheme mentioned above, optimum ore feeding amount can be timely and accurately determined, the adjustable range of ore feeding amount of an ore mill can be timely and accurately determined, and thus the ore feeding amount adjustment of the ore mill can be timely and accurate, so that the quality and efficiency of the ore milling process are indirectly improved.
Description
technical field [0001] The application relates to the field of ore dressing process control, in particular to a method and device for obtaining the optimal ore feeding amount of a grinding machine. 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...
