CALCULATION OF MAXIMUM BALL SIZE FOR BALL MILL GRINDING

CALCULATION OF MAXIMUM BALL SIZE FOR BALL MILL GRINDING

Jun 25, 2018Mill effective diameter = 2.23 m . 335 is a constant used for dry grinding with steel balls in the mill. Actual size of media is taken is lower than the calculated value. It is around 80 to 90 mm. If you Wants to reduce the maximum ball size, thenreduce the feed size by using pre grinding operation.

Ball Size as Initial Charge. Commercial ball sizes 10 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dV = 0.40 KF

The starting point for ball mill media and liquid charging is generally as follows 50% media charge. Assuming 26% void space between spherical balls (non spherical, irregularly shaped and mixed size media will increase or decrease the free space) 50% x 26% = 13% free space.

Ball mill

Ball mill

A ball mill is a type of grinder used to grind and 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

How can one select ball size in ball milling and how much

All Answers (4) More balls with small size results in fine powder. As a thumb rule powder to be milled should be taken as 25% of total ball weight. If the quantity of charge is very less then milling balls will start to collide with each other and no milling will take place. Ball size depends on initial size of charge and ranges from 10mm 150mm dia.
