LIMESTONE CHARACTERISTICS Ball Mill sizing is based upon tonnage, feed size, product size, operating or test plant data or the Bond Work Index Method. The Bond Work Index indicates a relative grindability of the limestone. The Work Index number (WI) is developed by grinding a small sample of the material in a laboratory unit using a defined procedure. The power requirement for grinding, based on the Bond WI (typically 9-13 for limestone), is defined as follows (where P=80% passing product size and where F=80% passing feed size): Worldwide awareness of environmental issues mandates regulatory...

Control Circuit For Wet Limestone Grinding Systems The control circuit of a wet grinding system controls the delivery of ground limestone slurry, on demand, to the product slurry tank from one or more grinding mills. Control methods range from manual to fully automatic utilizing Programmable Logic Controllers (PLC) or complete Distributive Control Systems (DCS). In the automatic mode, the grinding system is controlled by the slurry level in the reagent product storage tank and the mill discharge sump. When the product tank reaches high level, the feeder stops; after a time delay, the clutch de-energizes;...
