are ball mills as a primary classifier

Where the finished product does not have to be uniform a ball mill may be operated in open circuit but where the finished product must be uniform it is essential that the grinding mill be used in closed circuit with a screen if a coarse product is desired and with a classifier if a fine product is required In most cases it is desirable to operate the grinding mill in closed circuit with a screen or classifier as higher

Ball Mills from Raymond Bartlett Snow ARVOS Group Ball mills size reduction and classification equipment The Ball Mill or tube mill as these are generally called are used for a wide variety of applications where

A ball mill is a type of grinder used to grind blend and sometimes for mixing of 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

Ball mills are employed in either primary or secondary grinding applications In primary applications they receive their feed from crushers and in secondary applications they receive their feed from rod mills AG mills or SAG mills

In North America stage grinding is often carried out with ball mills as primary grinders and tube mills for fine grinding in the second stage OLD ORE GRINDING MILLS Stamp Mills Although the stamp mill could be classified as a fine crusher it is included in this chapter as its usual duty corresponds approximately to that of a primary ball mill

AG Mill Ball Mill Crusher ABC Circuit This can be used to correct a too coarse product from the primary mill Mostly operated wet but also dry possible

In order to get a steep particle size distribution curve the mill is used in closed circuit with some kind of classifier and the coarse particlesknown as classifier underfloware recycled Furthermore it should be observed that a grate discharge ball mill converts about 20 more energy than an overflow discharge mill with the same shell dimensions

From a theoretical point of view the ideal method of grinding would consist of a series of ball mills each in closed circuit with a classifier and each so short that the ore in its passage through the mill would be struck only two or three times by the balls any undersize produced being removed at once by the classifier in this way the chance of a particle being struck again after it had reached the required size

Calculation of Circulating Load in a Classifier A mechanical classifier often receives its feed from a ball mill and produces 1 finished material which overflows to the next operation and 2 sand which returns to the mill for further sizereduction

Prater’s Air Classifying Mills operate by using the combination of twostage closed circuit grindingmilling with an interstage air classifier all in one convenient unit The internal air classifier continuously recirculates particles that are larger than desired back into the grinding zone ensuring an optimal final product particle size

Media ball sizes for example range from about 20 mm for fine grinding to 150 mm for coarse grinding Tumbling mills are typically employed in the mineral industry for primary grinding ie stage immediately after crushing in which particles between 5 and 250 mm are reduced in size to between 25 and 300 µm

Summary The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium eg steel balls cylpeb and pebbles put in the shell and
