# density of ball mill run

where db.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3 ); D is inner diameter of the mill body (m). Generally, a maximum allowed ball size is situated in the range from D /18 to D /24

• Ball Mill Design/Power Calculation

Jun 19, 2015 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

• How Can I calculate new ball size and weight desing

Mar 10, 2011 But remember it all depends on your mill feed size after pregrinding. This is the raw mill not the finish mill. So Wi should be 11 and density of 2.67 as normal kiln feed. I used d80 of 3500 micron to be on safe side and got max ball dia. of 41 mm (use 50 mm steel balls)

Feb 16, 2018 How to safely and effectively use a ball mill to grind pyrotechnic chemicals and black powder. ... The density of the mill dust, and therefore the volume it occupies, will vary a bit with the density of the charcoal used. Pine charcoal is quite a bit less dense, occupying more volume per ounce than commercial airfloat. ... After a mill run, the

• Comparison of grinding media—Cylpebs versus balls

Nov 01, 2004 The data of mill feed and product of the last run in the locked-cycle grinding test are used for fitting the breakage rate parameters of a ball mill model (Napier-Munn et al., 1996), which are then scaled-up to simulate the full scale operation. However, some problems associated with the locked-cycle test were identified (refer to the next
