In starting the grinding circuit after anything but a very short shut spitars enough to clear the same packed on the tank bottom, start the classifier overflow pump, then start the classifier, and after that, the ball mill.
listen to the grinding process within the mill to further understand the process of grinding in large mills. Expert Computer Control In The 1970s Computer based control in the 70s was an experiment. Debate centered on whether or not direct computer control was advisable or foolish. Distributed Control Systems
Ensure that the lime shut off valve to the ball mill is open. Start ball mill lime timer. The lime control valve should be pulsing open for 3 seconds every 30 seconds . Open sodium cyanide shut off valve until fully open. Normal Ball Mill and Grinding Circuit Operation
Ball Mill FEED BOX. Ordinarily the feed box for a scoop tender is designed and supplied by the user. The feed box should be so constructed that it has at least 6 clearance on both sides and at the bottom of the scoop. This clearance is measured from the outside of the feed scoop.
Our PERI AutoCharge Mill Grinding Ball Charging System is designed to provide a controlled continuous supply of balls to maintain consistent ball loading in the grinding mill. Continuously charging grinding balls will allow your mill to maintain a consistent power draft, charge volume, ore feed rate, or consumption average . Our system effectively mitigates the number of variables in the control formula of your mill to optimise the performance of your operation. A safer work environment
These outcomes come from the fact that in the ball mills, the axial dispersion is higher rod mills; thus, the mean residence time is shorter in the ball mills . Table 4 . Effect of feed rate on the mean residence time in ball and rod mill .

Reliable and effective grinding technology for diverse applications. With more than 100 years of experience in developing this technology. Outotec has designed, manufactured and installed over 8,000 ball and pebble mills all over the world for a wide range of applications.
Ball Mill Power 800 HP. Detailed Process Description and Control: Crushed ore in the fine ore bin flows through a slot feeder onto a 30 variable speed belt feeder. The bin low level alarm on the mill control panel annunciator will inform the mill that there is a shortage of feed material. The belt feeder has level and
Another strategy to control the mineral feed is to control the electric current or power of the elevator. The current is a meassure of mineral mass milled. If you control the current with the mill feed you39;ll reach a stability of the mill. The electronic ear is a good measure for alarm but not for control. I hope i can help you David Fernandez ...
