Dec 23, 2013· SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length. Vertical mill is used in grinding material at smaller particle sizes, which is used after ball mill. Pebble mill is used when product contamination by iron from steel balls must be avoided.
The results are instruments characterized by their superior technology and outstanding reliability for each individual application in sample preparation and particle size analysis. This philosophy is reflected throughout the whole range of RETSCH products, which are arranged in three segments:
In these cases, the feed to the ball mill may be from 10 to 100 mesh or even finer. ... Rod Mills has a very define and narrow discharge product size range. Feeding a Rod Mill finer rocks will greatly impact its tonnage while not significantly affect its discharge product sizes. The 3.5" diameter rod of a mill, can only grind so fine.
Apr 24, 2015 ... Ball mill consist of a hollow cylindrical shell rotating about its axis. ... Ball mill produces 1 to 50 tonn/hr of powder of which 70 to 90 % will pass through a 200 mesh screen and energy requirment of the ball mill is about 16 kwh/tonn ... Weight of the balls: With a heavy discharge of balls,we get a fine product. Read More
Then the undersize product and circulating load are screen analyzed, and the average of the last three net grams per revolution (Gbp) is the ball mill grindability. When F is the size in microns which 30 per cent of the new ball mill feed passes, P is the microns which 80 per cent of the last cycle sieve undersize product passes, and P1 is the ...
of the wide variation in kinds of comminution events in the ball mill and because of possible untouched feed, the ball mill product follows equation (2a) only in the finer sizes, with large deviations in the coarser sizes. In terms of the kinetics of particle formation in a ball mill. one

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. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
