A: Our ball mill used for wet or dry type stone powder grinding.Feeding size 25mm, discharging size 200 mesh-325 mesh.Q: I need silica grinding mill, do you have? A: Yes, we have designed and export many this kind mills, for quartz grinding, 40-100 mesh, Fe free.
Advantages of this ball grinding mill include: less friction, less energy and more easily activated, because large diameter double row self-aligning roller bearing instead of sliding bearing is used as the main bearing.
And with the decreased grain size, the necessary ball size also decreases (Olejnik, 2010; 2011).For each grain size there is an optimal ball size (Trumic et.The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding.
Ball Mill Design/Power Calculation - Mineral Processing and …,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 .

Feed size and mill performance and manipulate feed size to obtain efﬁciency improvements (Morrell and Valery, 2001).The speciﬁc energy does not just depend on ore competence but also on factors such as feed size and ball load (Morrell, 2004).
The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s crushing ratio is smaller.The feed size is usually between 20-30mm and the product size is 0-3mm.
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.

Higher capacity than A-G mill grinding; Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm) High capacity (short retention time) Less sensitive to feed composition (critical size material) Semi-Autogenous Mill Note the size of the mill: Why does the diameter need to be .
How Ball Mill Ore Feed Size Affects Tonnage Capacity.The important of crushing your ore and rock fine and properly is often forgotten The finer you crush the higher your ball mill tonnage and capacity will be The effect of ball mill feed size and how it affects circuit throughput can be hard to estimate Here we described a method of designing a crushing plant using power drawn and power rate .
Limestone Wet Ball Mill2climestone Feed Size Ball Mill.
Mill Linings: Ball and Pebble Mills may be lined with rubber, ceramic and wear resistant metallic liners.Grinding Media: Mills may be charged with ceramic, steel and alloy steel grinding media.These are spherical or cylindrical in shape and range from 6 mm to 100 mm in size.
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, i.
Product size is estimated as a func tion of size and hardness of the mill feed, and milling operating conditions (Napier-Munn et al.A more reali stic approach is the so-called Population .

Tests were done, using samples from a platinum mine, namely the feed to a secondary mill (ball-mill) and rounded pebbles from a primary AG mill.Grinding capacity was maintained over the range 0 .
The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill for example a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills .
The feed rate for ball mill and the size is 900x2100MC .How Ball Mill Ore Feed Size Affects Tonnage Capacity.The important of crushing your ore and rock fine and properly is often forgotten.The finer you crush the higher your ball mill tonnage and capacity will be.The effect of ball mill feed size and how it affects circuit .
The throughput capacity and efficiency of a SAG mill are affected by the significant recirculated load derived from over-size discharge product (critical size “pebble” discharge) that is screened out and may be stockpiled or requires secondary crushing prior to re-introduction to the SAG mill feed.Where the SAG mill/ball mill circuit is .
Production Capacity: 22-250t/h.Ball mill is the material to be broken, and then smash the key equipment, widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other production .
Ultra Fine Grinding Mill Advantages 1.High grinding efficiency: save 20~30% power consumption compared with the ball mill.Strong drying capacity: dry and grind raw materials with moisture content as much as 15%.Mutifunction: crushing, drying, grinding, separating and conveying.
17 Size Reduction of Solids Factors influencing the size of the product : (a) Feed rate : With a high feed rate, less size reduction is resulted since in this case the material is in the mill for a shorter time.(b) Properties of the feed material : With a hard material, a smaller size reduction is achieved.(c) Weight of balls : With a heavy charge of balls, we get a fine .
Grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc.
When the feed size of a SAG mill becomes coarser, i.α r increases, the energy required to break the ore increases, i.φ r and φ f increases (Morrell et al., 1996; Morrell and Valery, 2001 .
