Feb 08 2017 The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media as well as a lot of noise. Most of the energy useless lost during ball mill operation leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.
Early models were not very reliable. 3C.3 Internal Water Sprays in Ball Mills Most cement finish mills employ some type of internal water spray to control mill discharge temperatures. Through proper control of the mill internal temperatures the operator influences a Gypsum dehydration which impacts false set performance or in isolated cases.
