CONTROL CIRCUIT FOR GRINDING MACHINE

A grinding machine includes the circuit as well as working components including a grind wheel, a feed arm and a feed arm sensor. The circuit is responsive to the feed arm sensor, such that the control circuit does not initiate the grind wheel unless the feed arm is retracted.

How to Operate a Grinding Circuit

2016-4-25  Controls for Grinding Circuit: Feed Rate: Increase from too low. Coarser grind, more circulating load. Effect on classifier overflow depends on fineness of ore feed and amount of increase in feed rate. Decrease from too high. Finer grind, less circulating load. Probably more fine sand in classifier overflow. Ball Mill feed water: Increase
