Grinding mill control system W R Grace Co
19 In a digital computer system for control of grinding mill operations the improvement comprising, a sensor providing a signal representative of a mill grinding condition, a computer programmed to arithmetically derive from said signal an error signal representative of the deviation of the sensed signal from a predetermined operating condition,A grinding mill such as an autogenous mill or ball mill, having a large driving gear driven by two motors, wherein a soft start capability is provided by a clutch or clutches, is "fingerprinted" in relation to the reduction gear system in order to identify optimum conditions for locking up the drive to achieve substantially equal loading between the drive motors, and to diminish cyclic variations in loading Grinding mill control system Dominion Engineering FEED MILL GRINDING ROLLING CONTROL SYSTEMS With EAI’s Grinding and Rolling Control package, you have total control over your process Features like auto gap control, bin keep full, and mill optimization keeps your system working hard for you Our feed mill grinding and rolling control system adapts to any hammer mill Feed Mill Grinding Rolling Control Systems Easy
Grinding Mill Control Types Grinding Classification
The required sound level (DB) is entered manually as a set point into the Expert System, the sound of the mill charge motion is measured by 4 microphones adjacent to the SAG Mill shell, and the resulting signal is transmitted to the Expert system which, in turn, sends a set point to the SAG mill tonnage and speed controller The Control philosophy controlled to a mill load setpoint by automatically adjusting the ore feed rate, and the acoustic control controlled the mill speed This is all a commissioning exercise and one of the things we wanted to do was incorporate an additional loop whereby mill speed is automatically adjusted to control mill Grinding Mill Control Grinding Classification process for the key features of automatic control of grinding mill is at medium filling rate meet the technical requirements of the premise, to control the amount of ore to the mill, the mill the ore loading is always at the right within range, to prevent mill overload or under load, to ensure grinding sizeAn Intelligent Control System for Complex Grinding
