ball mill motor selection

Homemade Ball MillBrianRedmond
In order to obtain a good quality powder you ll need a ball mill (among other things). I designed mine based on Dan Williams information and it worked great. The heart of the mill is the motor. I used a ½ hp 1725rpm 115v motor that I found on e-bay. There is usually a wide selection there with decent prices.

What size stepper motor do I-need.MYCNCUK
A Tutorial on motor torque calculations A question oft asked on MYCNCUK is "how big a motor do I need ". There is no simple answer to this and the options are usually a) follow someone elses build and copy theirs b) take a guess and try again if you are wrong or c) work it out which is the subject of this tutorial. When choosing a motor you need to know a) what power and torque output is

Determination and scale-up of the milling parameters of
An experimental laboratory scale ball mill available at the University of Lubumbashi was used in this research work. The ball mill measured 0.305 m in diameter and 0.127 in length. It was driven by an asynchronous motor rated with power close to 10 kW. A schematic of the experimental laboratory ball mill used is shown in Fig. 3.

AMIT 135 Lesson 7 Ball Mills CircuitsMining Mill
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.

The mill power draw models used in SAGMILLING.COM all reference power as drawn at the mill shell. Most surveys report power values as they are measured in the plant distributed control system (DCS) which is usually relative to the motor input power. Refer to the Measurement of power article for description of how to convert DCS indicated power

A poorly rewound motor may lose up to 3 in efficiency. A 100 HP motor may use several hundred dollars more in electricity each year due to this drop in efficiency compared to its original efficiency. The operating cost may be even more compared to a new high efficiency motor. References 1 wikipedia 2 seedt.ntua.gr
