Ball mills are usually either of the grate diaphragm or overflow type ball mill components ball mills consist of the following components inlet crushed ore is fed to the ball mill through the inlet a scoop ensures the feed to the mill is constant discharge reduced feed exits the mill through the discharge ball mill components
Jul , slip ring induction motor it has high starting torque and large overload capacity the speed of slip ring induction motor can be changed up to of its normal speed slip ring induction motor is used for those industrial drives which require high starting torque and speed control such as lifts, pumps, winding machines, printing presses, line shafts, elevators and compressors etc
Efficient induction motors for pumps, fans and compressors precise motion control motors with high performance and handling dc motors and persuasive highvoltage motors for use in compressors in the oil and gas industry, ore mills, rolling mills and ships severe duty and explosion proof motors for some of the worlds toughest operating
Abb ringgeared mill drive solutions offer a modular concept that provides a common drive control platform for induction and synchronous motors in single and dualpinion configurations these drives are wellsuited for all type of mills and ball mill applications,
Variable frequency supply to an induction motor may be obtained by using a cycloconverter as has already been discussed, a cycloconverter is a single stage frequency conversion device which converts ac line frequency to a variable frequency a cycloconverter feeding three phase induction motor drive is shown in fig
Ball mill for sale approximate capacities all ball mills operate on the same principles one of these principle is that the total weight of the charge in the millthe sum of the weight of the grinding media, the weight of the material to be ground, and any water in the millis a function of the percentage of the volume of the mill it occupies
Sep , it may not be as simple as a hp replacement, you really have to analyze the torquespeed requirements of the ball mill before making that decision a vfd on a standard induction motor is good at making sure the motor can supply a constant level of torque regardless of speed

Cycloconverter control of induction motor drive has applications in high power drives requiring good dynamic response but only low speed operation eG in ball mill in a cement plant the low speed operation is obtained by feeding a motor with large pole numbers from a cycloconverter control of induction motor operating at low frequencies
Our gmd eliminates all mechanical components of a conventional mill drive system, such as ringgear, pinion, gearbox, coupling, motor shaft and motor bearings by mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor
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 v 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

Jul , intermittent periodic duty with starting and braking in this type of drives, heat loss during starting and braking cannot be ignored so, the corresponding periods are starting period, operating period, braking period and resting period, but all the periods are too short to attain the respective steady state temperatures, these techniques are used in billet mill drive, manipulator drive, mine
An induction generator is a type of asynchronous generator, meaning the waveform that is generated is not synchronized to the rotational speed permanent magnet generators are simple and reliable and can work at low speeds, so they are ideal for use with wind turbines
An induction motor or asynchronous motor is an ac electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding an induction motor can therefore be made without electrical connections to the rotor an induction motors rotor can be either wound type or squirrelcage type
