Jun 18 2021 At present these two measures are the main reform directions for the cement mill optimization. The following effects can be achieved the output is increased by 30 -60 the power consumption is reduced by 25 -40 and the power consumption per ton of cement is reduced by 8-12kWh. It can effectively increase the strength of cement.

Abstract Ball mills like other comminution devices consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated with a.

Energy Saving Ball mill. Feed Size≤25mm. motor power18.5-800KW. processing power0.62–90 th. Applicable Material Ball mill is key equipment for grinding materials after crushing process. It is used to grind kinds of materials into fine powder 20-75micrometer. Based on discharging type It could be grate typeoverflow type etc.

Grinding mills are classified by the media used for grinding. The more common types of mills are Ball mills - These mills use forged steel balls up to 5 inches 127 mm in diameter to crush and grind the material. Mill length is two or more times its diameter. Rod mills - Steel rods up to 4.5 inches 114 mm in diameter and slightly shorter.

Wiki says A ball mill is a type of grinder used to grind materials into extremely fine powder for use in paints pyrotechnics and ceramics. Many instructables refer to United Nuclear Ball Mills. Their small ball mill cost between 70 and 80 dollars. For no more than 30 and in 5 minute you can build a ball mill of appreciable performance.
