Gmotor Power Calculation For Ball And Tube Mill

ball mill design/power calculation - 911 metallurgist,example calculation. a motor with around 1400 horse power is calculated needed for the designed task. now we much select a ball mill that will draw this power. the ball mill motor power requirement calculated above as 1400 hp is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. the following shows how the size or select the matching mill required to draw this power is calculated.ball mill motor power draw sizing and design formula,the following equation is used to determine the power that wet grinding overflow ball mills should draw. for mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. this is called the ball size factor s..amit 135: lesson 7 ball mills & circuits – mining mill,the motor power draw required to turn a mill from rest to the operating speed includes the energy required for the initial starting torque and mechanical arrangements to rotate the mill. it is generally accepted that practical mill power (pm ) is a function of mill capacity and diameter, i.e.,p m = mill constant * (mill diameter ) n.ball mill: operating principles, components, uses,the balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. the large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. ball mills grind material by impact and attrition..
