Yesterday I calculated the power draw of our ball mill. I attach a graph of it. Is it possible to have calculated mill power draw to be greater than mill motor HP? Calculated mill power draw is 1,509 HP; Mill motor HP is 1,500 HP According to the calculations, at 54% mill volumetric loading, max power draw of 1,796 HP is obtained.
Overview of Ball Mills. As shown in the adjacent image, a ball mill is a type grinding machine that uses balls to grind and remove material. It consists of a hollow compartment that rotates along a horizontal or vertical axis. It's called a "ball mill" because it's literally filled with balls. Materials are added to the ball mill, at ...
ball mill: [noun] a pulverizing machine consisting of a rotating drum which contains pebbles or metal balls as the grinding implements.

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
A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power. The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how ...

The twin dc motor drive system with each motor connected to a pinion and each fed from a static thyristor power supply has been successfully installed and operated at the Lornex Mine in British Columbia on a m (34 ft) mill rated at 9,325 kW (12,500 hp). Load sharing of two dc motors has been successfully achieved over a very wide range of ...
The Ball mills are operated by inbuilt motors to rotate the drum. The ball mill are in operations in refractory Industries are daily about 14 hrs for making unshaped refractory material. The environment in ball mill area is dusty and wet which will affect the efficiency of motors and other parts of machinery. If the ball mill motor is ...

Larger HP motors are better than smaller, as they carry a load better run cooler. A ball mill load of numerious type comps, is a bomb waiting to happen. Best prevention is to invest the bucks build one safe as possible. I would rather the safe, than sorry. The difference between stupidity and genius is that genius has its limits ...
1The jar will contain metal balls which will be a heavy load to rotate. (I think 1/3 HP at least would be needed) 2The jar rotation should be constant (80 RPM). 3It will run for long time < at least for 11 continuous days. I have an old washing machine (Universal motor) but I think it will not be suitable since it will overheat due to the ...
The first finish ball mill driven by a wraparound motor has been put into operation in 1969 in Le Havre, France. The cement output is rated at 200 MTPH and the motor rating is 8700 HP (metric HP), equal to 6400 kW at 15 RPM. The motor was manufactured by Brown, Boveri and Comp., Baden, Switzerland.

DIRECT CONNECTED Ball Mill DRIVE. When power exceeds 300 HP a direct connected drive is recommended. This drive is also applicable for lower power requirements if desired. Synchronous motors are preferred, but in some cases wound rotor motors may be used. Motor speeds will vary from 225 rpm to 450 rpm.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...
