The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum a...
The ball mills, the second stage grinding equipment, are in diameter and long, each with two 7800 kW motors. 52 magnetic separators are used in each of the processing lines. Two concentrate thickeners, each 45m in diameter and four tails thickeners each 90m in diameter. Four dewatering buildings, each containing seven press filters.
The smallest ball size typically charged into ball mills and tower mills is ½ inch ( mm), although media diameters as small as 6 mm have been used industrially in Vertimills. In a laboratory study by Nesset et al .,[ 7 ] a GIS mill charged with 5mm steel shot, and with other operating conditions similarly optimized, achieved high energy ...
2. From the ball mill discharge size distribution calculate the %+75 μ as: 100 % = % +75 μ. 3. Calculate the CSE as the average: ( + ) ÷ 2 = % + 75 μ. In this example the ball mill circuit classification system efficiency is per cent at 75 μs. This means that

Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^ where D m = the diameter of the singlesized balls in = the diameter of the largest chunks of ore in the mill feed in mm.
1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
Figures 3a 3b give the power for an autogenous mill. Figures 4a and 4b are for the same size mill with a ball charge of 6% of mill volume (290 lbs. per cubic foot). In the above example the power was calculated for a 30% volume. However, with the same sheets the power can be determined for any volumetric loading from 15% to 35%.

Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than highspeed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.
Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually times the shell diameter (Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or ...
The RP4 shaker table is the most widely used and most successful gold gravity shaking concentrating table worldwide, used by small and large mining operations and hobbyists. The patented RP4 is designed for the separation of heavy minerals and gemstone concentrate. The RP4 table can process up to 100 lbs. per hour of black sand magnetite or pulverized rock with little to no losses. The RP4 ...
The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where ...
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

The numerator is calculating the volume of one swing of a jaw, times the density of material in the chamber, times the number of cycles per minute. This should give you the mass of material crushed per minute. The denominator looks wrong; to convert to mass per hour should be multiplying by 60, not dividing by 60. Dividing by 60 should give mass
