the size range of balls provided to support the tests is from 12.5 to 40 mm. the size of ball varies with the requirement of the tests and complied standard. the laboratory ball mill capacity also varies according to the application and ranges from 5 to 20kg. the equipment is provided with a counter for recording the number of revolutions.
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 the bottleneck in the processing plant the pebble circuit can be a significant factor in limiting overall plant capacity.
10-350mm. capacity. 1-95t/h. input size. <25mm. ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or
example: mill cylinder total capacity = 60 cubic feet. amount of product to be used for 25% loading = 15 cu. ft. 25% is the maximum recommended product loading for dry grinding applications. for wet grinding applications the mill may be loaded up to 60% of cylinder total capacity (see below)
a ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. it works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. a ball mill consists of a hollow cylindrical shell rotating about its axis. the axis of the shell may be either horizontal or at a small angle to the horizontal. it is partially filled with balls…
typical end-fineness for a high quality chocolate or compound coating will be around 18 to 20 (metric!) microns. deepening on the required capacity we can have one single ball mill or two (sometimes even three) in series. for smaller production runs we also offer stand-alone batch ball mills called a ‘wiecon’.

while the quality of steel balls determine the capacity of ball mill grinder. the quality of the steel ball is calculated according to the amount of ore processed per ton (ie 0.8kg per ton of ore). the average steel ball needs to process one ton of ore (1kg-1.2kg). in general, the ratio of ball mill ball is a complicated technical problem.
