Jul 05 2020 A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis The balls which could be of different diameter occupy 30 – 50 of the mill volume and its size depends on the feed and mill size.Rod Mills are similar with the Ball Mills xcept they use long rods for grinding media The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 1 4 to 1 6.
8 3 2 2 Ball mills The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–1 5 times the shell diameter ( Figure 8 11) The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight.The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill AG SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill.
Why The Ball Mill Is Efficient Than The Rod Mill Capacity 1 1000t h Pdf effect of circulating load and classification pdf effect of circulating load and classification The ball mill is the most common ore grinding technology today and probably than 50 of the total world energy consumption for ore grinding is consumed in ball mills why the ball mill is efficient than the rod mill.Rod mills are very similar to ball mills except they use long rods for grinding media The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 1 4 to 1 6.
The Rod Mill is the same as the Ball Mill in the construction and available to both of wet and dry processing Unlike the Ball Mill however the Rod Mill uses rods instead of balls as the grinding medium As a result its uses are different from those with the Ball Mill In other words the Rod Mill gives impact on and grinds coarse particles.Rod mills are very similar to ball mills except they use long rods for grinding media The rods grind the ore by tumbling within the mill similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 1 4 to 1 6.
Oct 12 2017 SAG mill make use of steel balls included with some large and hard rocks for grinding These mills utilize the balls in making the large fragments of materials broken into pieces The ball charge of a SAG mill is about 9 to 20 This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.The NRRI explained “Traditional taconite pellet making processes use a rod mill to get the rock to the consistency of coarse sand and a ball mill to grind the rock into a fine powder This technology is still in use on Minnesota’s Iron Range by some facilities “A taconite plant may have as many as 18 rod mills with one rod alone.
Nov 26 2019 Buy ball mill Ball mills are fine grinders have horizontal ball mill and vertical ball mill their cylinders are partially filled with steel balls manganese balls or ceramic balls The material is ground to the required fineness by rotating the cylinder causing friction and impact.The Bond Index conforming rod charge consists of 6 rods of 1 25“ diameter and 21“ length 2 rods of 1 75“ diameter and 21“ length The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave shaped design At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.
