Abstract

The invention is directed to the technological field of bowl mill ore-feeding amount control. Specifically speaking, the invention relates to a bowl mill ore-feeding amount intelligent control apparatus, comprising a PLC provided with a PID controller and a fuzzy logic controller, an input parameter sensor, a hand-operated / automatic change over switch, an ore-feeding amount setting apparatus, wherein the fuzzy logic controller, the input parameter sensor, the hand-operated / automatic change over switch and the ore-feeding amount setting apparatus are respectively connected to the input interface of the PLC. The input interface of the PLC is connected with a bowl mill ore-feeding disc frequency converter. The fuzzy logic controller is an ore-feeding fuzzy logic controller. The input parameter sensor comprises a bowl mill ear, a bowl mill load sensor, a cyclone pressure transducer, a cyclone overflow granularity sensor and a belt electronic scale. The input parameter interface is connected with the fuzzy logic controller. According to the invention, the problem of different ore-drawing granularities caused by an inconsistent control on the ore-feeding belt is solved, the efficiency of the bowl mill is maximally improved and the output increases.

Description

technical field [0001] The invention belongs to the technical field of ball mill feeding amount control, and in particular relates to an intelligent control device for ball mill feeding amount. Background technique [0002] The ore feed rate of the ball mill has always been the biggest factor affecting the grinding effect of the ball mill. The existing ball mill feed rate control method is to use human experience to control the ball mill belt feed rate. This has a lot of limitations, it is not easy to accurately grasp the amount of ore feeding, everyone has different experience, the particle size of grinding is not easy to control, and the operating efficiency of the ball mill cannot be maximized. [0003] The existing Outokumpu ACT grinding automatic control system requires an independent server to collect and analyze on-site data, which requires a large investment; a set of pure software control programs independently developed by VC development software, and the communic...
