Jun 25, 2018· Let, The Size of the mill feed (80% passing) =F (microns) Work index for the feed = Wi kwh/s.ton %age of mill in critical speed = Cs (percent) Specific gravity of the feed = S (gm/cm3) Mill effective diameter = D (meter) Then, Maximum ball size for ball mill grinding is B(mm) Example: Size []

21 CONCLUSIONS Continued In the present work, equations were also derived, giving: zthe ball-mill power drawP as a function of its dimensions: internal mill diameter D and length L, zthe ball-mill power drawP as a function of the feed D f (mm) and the product size d (mm), the Bond work index w i (kWh/short ton) and the mill throughput T (short ton/h), zthe ball-mill dimensions (D

The mill (with 30 cm in diameter and 30 cm in length) and the test conditions are standardized, with a maximum ball size of 40 mm and an ore top size of 3.35 mm. With less than 300 balls, it poses no challenge in running the simulations, if only grinding media are included. For such a small mill, one could also include the ore or powder charge.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

rate at each screen size is calculated from a torque-mill test as in the example that follows. Torque mill solids load during test: 11.25 kg (24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be the same percent solids as the plant ball mill discharge. Mill speed: 35.2 rpm (65 percent of critical speed)

Every mining operation has a unique grinding process. Variable needs require versatile grinding equipment. Metso offers flexible autogenous (AG) mills, semi-autogenous (SAG) mills, ball and pebble mills, as well as stirred mills to fit your needs. Grinding mills, spare and wear parts as well as maintenance and optimization services.
