Ball Mills
Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turn-key ...

Ball End Mills | McMaster-Carr
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.

Ball Mill
A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for single-stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits.

Self sufficiency in action: Shetland's ancient mills
It's thought that the design reached Scandinavia via Ireland, where such mills existed before the Vikings arrived. The assumption is that the Vikings brought the design to Shetland, Orkney, and the Western Isles, so there may have been mills of this kind in Shetland for 1,100 years or so.
