Hello everybody, I have a ball mill that my brother made. It's a 24" drum by 36" long. It's powered by a gas engine that runs a hydraulic motor. It works really well, but I'd like to convert it to an electric motor. The whole setup is in my shop, and the engine is a bit noisy. I …
Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a …
These are a good motor for ball milling, they are designed to operate under load for long periods, sometimes multi speed and reverable to boot! They are supposed to be wired with a starting capacitor, but I could never work this out, so I just plug it in and spin (hand) it in the direction I want it to go. Great motor.

flow Study of all low voltage motors installed on site as well as drive and cable selections for each. The second is the implementation of a Mill Control System to control the operation of a 3MVA Ball Mill used for secondary crushing in the copper extraction process.
The motor is usually fitted with a variable speed drive (VSD) to control the rpm of the ball mill. Gearbox – used for speed reduction from the motor to the ball mill. Balls – usually manufactured from manganese alloy steel, but the material depends upon for what material the mill will grind ( chrome steel alloy and rubber also available).

The motor construction types consist of squirrel-cage type and winding variety. Between them, large-voltage synchronous motors largely support air compressors and mine ball mill gear. use. We adhere to the services tenet of "emphasis on products, services with coronary heart" and offer large-quality motor items to consumers.
A motor may use one to as high as seven or more grains in a motor or the propellant may be cast directly into the motor (case bonded grains) in which case the entire mass of propellant is referred to as the grain. ... The ball mill is the best way to grind and you can also grind all the ingredients for black powder together. A ball mill is ...
In the past the conventional method of driving large ball mills included some form of speed reducing gear between the higher speed driving motor and the lower speed ball mill. Process developments in the mining and cement industries have increasingly tended toward the use of ever larger ball mills for grinding their products. As the horsepower drive ratings required …

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, i.e. 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 Mills are widely used in the ceramic and mining industries, where the grinding process requires strict grain size control.
