The alpine anr vertical wet media mill is a wet media mill for ultra-fine grinding of medium to hard materials especially in the mineral powder industry the alpine anr vertical wet media mill product line includes several machine sizes with grinding chamber volumes ranging between 10 and 200 liters.
Feed size is usually inch or less; product size ranges from 500 to below 5 ball mills work well on hard brittle materials they are not as suitable for grinding elastic ductile or fibrous materials or for fine grinding in general ball mills can blend and grind at the same time yielding a fine intimate mixture.
Ball mills tumble iron or steel balls with the ore the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds the feed to ball mills (dry basis) is typically 75 vol-% ore and 25% steel the ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
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 openclosed .
The workshop needs to have good ventilation conditions and suitable temperature then the installer can enter the ball mill barrel to start the operation when removing the old ball mill liner first remove the used lining screws then remove the old ball mill liner one line after one line and then lift the used ball mill .
Ball mill production capacity:14-50th power:45-1000kw weight:12-156t ball mill is widely used in powder-making production line including cement silicate new-type building material refractory material fertilizer ore dressing of ferrous metal and non-ferrous metal glass ceramics etc.

Ball mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard soft brittle fibrous temperature-sensitive and moist samples down to the finest particle size the comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding .
Feed size should generally be -18 for ball mill and -12 for rod mill they are of a sturdy rugged design to handle frequent use with hard materials the batch ball and rod mills require a drive roll to rotate the mill the proper grinding speed usually 60%- 75% of the critical speed for ball mills and 50% to 90% of critical speed for .
Rod media are particularly effective in vibratory mills the line contacts between the media provide more interface areas spreading the grinding energy over many particles to keep the amount of size reduction constant ball-shaped media a general-use media coorstek ball media is .
