Motor Power To Drive Ball Mill

Ball Mill Drives - Mineral Processing & Metallurgy

Ball Mill Drives. One important advantage of the synchronous motor is the possible correcting of power factor within your operation, through its use. When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pull-in torque, and 225% pull-out torque. These assume no greater than a 10% voltage drop at the motor terminals.


gear box to a center drive mill; a Drive 4 - A 5000 HP, 1200 rpm induction motor with a VFD controller as a soft-start to a dual pinion gear driven mill; a Drive 5 - A 5000 HP, 1200 rpm synchronous - induction motor with liquid rheostat and dc field excitation to a dual pinion gear driven mill. For the power supply in this study, four different scenarios will be considered as a power system in order

Ball Mill Design/Power Calculation

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 from known tables ‘the old fashion way’.

What type of motor for a ball mill? - Tools and Tooling ...

What type of motor for a ball mill? - posted in Tools and Tooling: Hello, I am looking to get into pyrotechnics and I was just wondering what type of motor I should get for my ball mill? What rpm for direct drive? Also, would I be able to wire the motor directly to my mains (230v AC)? I prefer to make things myself when possible, its more fun that way so I was going to make a ball mill to make ...

Ball Mill Positioning -

the ball mill, the smooth variable frequency drive technology helps reduce maintenance time, reduces mechanical wear on the equipment and reduces money spent on maintaining the motor. The ability to operate a medium voltage motor with a 480VAC AC drive at very low speed for controlled positioning eases the spotting process

motor selection for ball mill -

Mar 09, 2016 · Re: motor selection for ball mill Only induction motor achieves long life. A motor with 2 or 4 pole pairs (1500 or 750 rpm @ 50 Hz) with pulley drive seems to be a straightforward solution. Or any other kind of geared induction motor.


AG/SAG mills in the data base are up to 40ft in diameter and ball mills are up to 26ft in diameter. The measured gross power draws from these mills are plotted against the model predictions in Figure 1. As indicated by this data base the accuracy of the model (1 standard deviation) is 4.6%.
