where d bmax 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 The degree of filling the mill with balls also influences productivity of the mill and milling efficiency

milling circuit consists of a rod mill followed by a ball mill in series Crusher product (9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass The rod mill discharge is pumped, without any further water addition, to the first ball mill The ball mill discharges to a sump where water is

the mill feed by abrasion and impact as the rods cascade within the shell A rod mill differs from a ball mill in that the comparatively rigid grinding media operate in a relatively fixed path and reduction results fram line rather than point contact between grinding surfaces Conventional rod mills are either high or law discharge In the high

• bond work index for the feed material • abrasion index for the feed material • maximum particle size of the feed to the mill • required F100 and F80 of the crusher product • percent moisture in the feed • proposed method of feed and discharge from the mill • permanent, modular or mobile application • available power source

Nov 01, 2004· When feeding the mill with harder material (right side of Table 1), the mill discharge becomes coarser Consequently, solids recovery, circulating load and solids content will increase With increasing solids content in the hydrocyclone feed the cut size is

Grate discharge Dry Grate discharge Wet Overflow discharge Wet Figure 85 Effect of mill filling on power draft for ball mills The data is taken from Rexnord Process Machinery Reference Manual, Rexnord Process Machinery Division, Milwaukee, 1976 The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure 84

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paintsBall mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls

Jan 03, 2016· Ball mill heat loss In the ball mill case, the energy balance found in equation (2) is sufficient as all the ore and water components of the slurry at the feed and discharge are at a similar temperature of T 1 and T 2 respectively Solving equation (2) for energy lost 𝑄̇ and using the data provided in Table 3, it is possible to estimate

Mill Type Overview Three types of mill design are common The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns; The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges

The final plan was to increase the ball charge in the SAG and ball mill to 10% v / v and 27% v / v, respectively; set the upper limit of the operating power in the ball mill to 5800 kW; use a TC Series crusher (without a power/feed rate–controlling device, but with a feed bin) to crush pebbles for recirculation back to the SAG mill feed

minevik has been working with grinding mill circuits in a wide variety of mining applications for decades minevik MD Series horizontal mill discharge slurry pumps encompass all the experience coupled with an understanding of today’s market needs and demands for improved performance
