Ball Mill

Ball Mill

Ball mill is the vital equipment for recrushing after being crushed.

Processing ability:0.5-500t/h

Feeding size:≤25mm

Applied material:cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc.

ball mill design/power calculation

The basic parameters used inball milldesign(powercalculations), rodmillor any tumblingmillsizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desiredmilltonnage capacity DTPH, operating % solids or pulp density,feedsize as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed

If themill feedsetpoint is changed, then the actualfeedrate needs to stabilise at the new target in a short period of time. Thefeedrate setpoint can then be tied

Forces onballinball millLet the radius AOformthe angle α with the vertical. Two forces act onthe ball. The first is the force of gravity: mg/g C where m is the mass ofthe ball. The second is the centrifugal force: (R - r) ω 2 /g C where ω = 2πn and n is the rotational speed. The centripetal component of the force of gravity is: (mg/g C) cos α this force opposes the centrifugal force

ball mills vs rod mills

When themillis rotated withoutfeedor with very finefeed, the rods are in parallel alignment and in contact with one another for their full length. Newfeedentering at one end of themillcauses the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the

Apr 01, 2008·Feedrate affects surface finish as well. The pass of each cutting edge as the tool advances creates a “cusp” of its own. Therefore, if a smooth surface is the goal, then the same value calculated as the limit of the radial depth should also be applied as the upper limit on the inch-per-toothfeedrate of the tool
