3522 ball mills the ball mill accepts the sag or ag mill product ball mills give a controlled final grind and produce flotation feed of a uniform size ball mills tumble iron or steel balls with the ore the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds

Smaller the required particle size of the final product is the longer time it will take a ball mill to grind the material which will decrease the ore grinding effect and the output 3 working condition according to a ball mills working principle materials are mainly ground by its grinding media

Ball mill is widely used in many industries the final product size can be adjusted the shape of the final products is circular and you can adjust the capacity and fineness by adjusting the diameter of the ball stable performance and long service life ball mill adopted quality materials and the barrel body and scaleboard are wearable well

The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill agsag mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill

Equation 2 the approach requires the feed size to the sag the sag mill product size transfer size and the final product size the prediction of the sag mill transfer size used in the formula is made by comparison with pilotplant data and operating plant data for similar ore types barratt 1989 the
