Grinding Ball Design

Ball Design Factors Size and Mass. Importance of size: Taggart (1927) stated "Size of balls should be proportional to the work to be done, i.e. the size of the particle that must be broken by impact, hence coarse feed and hard ores require larger balls than finer feeds and softer ores." The 9 to 10 m (30 to 33 ft) SAG mills now in …

High temperature of the ball mill will affact the efficiency 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded Reasons

Ball Mill Feeders

The entire mill feed enters the drum via a chute or spout and an internal spiral carries the feed into the trunnion liner. The drum feeder may be used in lieu of a spout feeder when headroom limits direct spouting. The drum also provides a convenient method of adding grinding balls to a ball mill. The drum is generally lined with Manganese Steel.
