each group. The 10-ton models in the 6 to 10 ton group have operating costs about 25 percent less per ton than those of 6 tons. Total costs for this group range from $15.16 to $7.20 a ton. The next group, 10 to 25 tons per hour, has a 42 percent reduction in costs from the low to the high. These per ton costs range from $14.52 down to $5.53.

The PFS has estimated the capital costs of the Project ("CAPEX") at US$1.93 billion, the total cost per ton milled ("OPEX") at US$13.12, the all-in sustaining costs ("AISC") at US$1,171 per ounce
Inventory ID: 6C-HM02. UNUSED FLSMIDTH 22'' x 41''6" (6.7m x 12.7m) Dual Pinion Regrind Ball Mill with 2 ABB 5,500 kW (7,375 HP) Drives for Total Power of 11,000 kW (14,750 HP)
As an example, the cost estimation procedure for a ball mill circuit that is closed by a cyclone is demonstrated in Fig. 3 (using the multivariate cost models). Variables D, L, and P (or one of them for uni-variate cost estimation) should be determined for application in the cost models (i.e., Eqs. , ). Size distribution of the ball mill
CONSTRUCTION (CONTD) The length of mill is approximately equal to its diameter. Ball occupy about 30-50% of the volume. The dia of ball is 12mm to 125mm. The dia of shell is 3m and its length is about 4.25m. The shell is rotated through a drive gear with speed 60-100 rpm. 10.

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 and finally the type of circuit open/closed
Ball Mill : Ball Mill for gold is a type of grinder. It 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
Ball mills require liners that are constructed from materials such as steel or rubber. For a 30 ft long ball mill with a Task #2 5 University of Arkansas 20 ft diameter, a hard rubber liner reinforced with steel can cost $150,000. These liners are replaced at least once a year, creating a substantial upkeep cost for these ball mills. Metal
Therefore, ball abrasion rate in the mill determined by Equation 10.

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
A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball mill/third-generation separator, CKP/ball mill/third-generation separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption.

Depreciation costs above are based on a HSM capex cost of $170/tonne depreciated over ~20 years; this cost could be significantly lower in the case of a narrow strip mill, and much higher in the case of a Steckel mill. Labour productivity may also be better than shown (e.g. in recently-built plants).
