Embodiment Construction

[0139] Embodiment of the present invention is a large-scale iron ore dressing plant. The raw ore of this concentrator is mainly pyrite and limonite, and the gangue is mainly barite, quartz, jasper and iron dolomite. The actual iron content of the ore is 33%. After the raw ore is pretreated (screening, magnetization roasting, etc.), it is transported to the cylindrical ore bin. The ore in the cylindrical ore bin is discharged by the electric vibration feeder, and then sent to the grinding process by the ore feeder belt conveyor. The grinding process consists of two stages of grinding circuits, and the first stage of grinding consists of a ball mill and a spiral classifier. The ore in the cylindrical ore bin is sent to the ore belt conveyor into a section of ball mill, which is mixed with the supplementary water at the entrance of the ball mill and ground into a slurry in the ball mill. The ore grinding in this section adopts a grid-type ball mill. The classifier and the spiral...

Abstract

The present invention belongs to the field of automatic control technology. The intelligent optimized control process for comprehensive production indexes in ore dressing process includes the steps of: setting technological indexes, setting control loop, controlling statistical process, predicting technological indexes with the nerve network, feedback compensation, feedforward compensation, etc. The present invention is superior in that based on the requirement of the ore dressing process in concentrate grade and metal recovering rate and through the said control process, the optimized set values for ore grinding work section and selecting work section are given and the loop setting values are then given to realize comprehensive production index optimization in the ore dressing process.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to an intelligent optimization control method for comprehensive production indicators in a beneficiation process. Background technique [0002] The beneficiation process is the process of enriching the useful minerals in the ore to be directly processed. It generally includes grinding process and sorting process. The basic task of the grinding operation is to crush the mineral raw materials to a suitable particle size, to dissociate the useful mineral components from the gangue, or to separate different useful mineral components from each other. The sorting process separates useful minerals from monomer dissociated minerals. The final comprehensive production index of the beneficiation process, that is, the metal recovery rate Rm and the concentrate grade Tf, are closely related to the process index grinding particle size R of the grinding process and the sep...
