Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. the variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications.
Ball mills give a controlled final grind and produce flotation feed of a uniform size. ball mills tumble iron or steel balls with the ore. the balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.
Ball size distribution in practice, at mill startup, instead of charging a single size of ball, usually a range of ball sizes is initially added.7.6 a ball mill is to produce a grind of 34 micron (pso) product from a feed size of 200 microns at a rate of 1.5 t/h.

Fast-cutting carbide ball end mills. variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. made of solid carbide, they are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material.
the apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ ball mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the shell is 5′ inside diameter and the working diameter is .

Media and product ball mill loading guide. (percentages are based on total volume of cylinder) note: with media load at 50%, voids are created equal to 20% of cylinder volume. these voids are filled when product is loaded into the mill. mills can be loaded by volume .
basic principle ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. to achieve a reasonable efficiency with ball mills, they must be operated in a closed system. there is a specific operating speed for most efficient grinding.
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., d †“v = 0.40 k ˆšf db = ball size (cm) f = feed size .
