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 have the ball mill inside an insulated box, so it's actually not to bad.

The replacement motor is a M line, 6400 kW, 6 poles, 6 kV and was applied to a raw material mill. WEG has developed a fully custom interchangeable motor for Novoroscement, adding the new brush lifting system of the M Mining line, delivering to the customer an up-to-date product with all the differentials mentioned above.
The ball mill is a drum-type grinding machine, its principle of operation is crushing materials with abrasion forces by special steel ball in a rotating chamber. Grinding balls are consumables, since they are worn at work. The balls are loaded into the working chamber through a special hole. The drum chamber is driven from an electric motor.
31.4.4.3) where the electrical shaft voltage potential will overcome the dielectric of the oil film and arc through the bearing creating an EDM pit. Since the VFD has a carrier frequency setting of 2000 to 16000 pulses per second, there are millions of pitting opportunities every hour of operation of the motor/drive system.
Eddie headed out to the MMG site to take stock of the specs on the ball mill and determine what the best coupling solution would be. "The body of the machine rotates at around 180 rpm from an 8-pole electric motor creating the speed down ratio through a gearbox," says Eddie.
Operation The grain is introduced to the mill via the hopper, the material flow must be regulated and even (optional feed mechanism required, for optimal results). In the milling chamber, hammers rotate at high speeds to pulverise the material in to particles small enough to be drawn through the screen by the fan.
High-energy ball mills equipment is becoming a standard for particle size reduction. This is due to the increasing demand for fine (<1 μm) product particle size and shorter processing cycles . Ball mill is one of the most predominantly used methods for the purpose of mixing and grinding of raw materials [17, 18].
Energy-efficient operation of pump drives in a cement plant PK Choudhary and SP Dubey Abstract Electric motors consume a large share of electricity in cement industries. Traditionally, most of the motor applications use variable frequency drive to save electricity, but they do not optimally minimize power consumption always.
Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.

An ELECTRIC MOTOR is an electrical machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Electric motors can be powered by direct current (DC) sources, such as from …
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.
