Home -- 18 X 18 Size Ball Mill Design
Our leading products have crushing equipment, sand making equipment, mobile crusher;The products includes five series: crusher, sand making machine, powder grinding mill, mineral processing equipment and building materials equipment.
Ball size as initial charge commercial ball sizes 10 150 mm; number size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge for the initial chargin of a mill coghill and devaney (1937) defined the ball size as a function of the top size of the feed ie d&226;v 040 .

Where d bmax is the maximum size of feed (mm); is compression strength (mpa); e is modulus of elasticity (mpa); b is density of material of balls (kgm 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 d24 the degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
Retsch is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application the high energy ball mill e max and mm 500 were developed for grinding with the highest energy input the innovative design of both the mills and the grinding jars allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming .

Jun 19 2015&0183;&32;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 .
First a jar mill grindability test requires a 5 lb (2 kg) sample and produces a direct measured specific energy (net hp-hrt) to grind from the design feed size to the required product size the second test a bond work index determination results in a specific energy value (net hp-hrt) from an empirical formula.
