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. "So, the coupling solution needed a high torque rating to ...
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

If doing this, it will be necessary to calculate the feed rate and speed instead of using the chart. Example using a 1/4" or 0.125" bit – Straight V Carbide Tipped Endmill SB# 13642: This bit is used for soft wood, at a depth of 1/2" (two times the diameter).
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 ...
Below 50-hp capacity, the four coupling types have similar diameters. But, as torque and shaft size increases, couplings with metallic members (grid, gear, and disc) have smaller ODs than ...

Essa® Bond Test-Work Equipment. Internationally accepted mineral metallurgical standard test procedures to determine the physical properties of ores include the Bond ball mill work index and the Bond rod mill work index. These are empirical indices determined by close circuit grindability tests developed by F.C.Bond in the mid 1930's.
An investigation was conducted to determine the effect of the ball diameter sizes on milling operation. A laboratory size ball mill was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively. Quartz was the material used to perform the experiment and was arranged into 3 mono-sizes namely -8 mm +5.6 mm, -4 mm +2.8 mm and-2

To calculate the motor power required for a cylindrical type ball mill, the following formula can be applied W = 0.04116 x D 3 x L x n x (0.6d + 0.4d1) Where: W = Required motor power in HP D = Internal dia. of the mill in mtrs. L = Internal Length of the mill in mtrs. d = Specific gravity of grinding media d1 = Specific gravity of substance

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
