• 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 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.  Rod and Ball Mills by Rowland and Kjos AllisChalmers

    Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.

  • Selecting Inching Drives for Mill and Kiln Applications

    The standard inching drive motor is a NEMA or IEC frame typically foot mounted to a motor scoop or base plate. Typical motor speeds are either 4 or 6 pole, 1750 rpm or 1170 rpm for 60 Hz applications and 1450 rpm or 970 rpm for 50 Hz applications. The advantage of using a four pole motor allows for a smaller footprint and a smaller brake if

  • Ball mill drive motor choices IEEE Conference Publication

    May 12, 2000· Abstract: The time has come to rethink the approach to mill drive motors because of the growth in size of newer ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness of some utility services. This paper looks at the serviceability and economics of five different mill motor options to meet these restraints.
