Operating at higher mill speeds can reduce operating costs by permitting operation at lower ball charges for a given mill power draw. Keywords Motor design, motor speed, mill speed, rated speed. Introduction The purpose of this paper is to provide guidance to Owners and EPCM engineers in the specification of the "design" and
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 …
• Universal modular milling cutter for face milling of steels, stainless and cast iron materials • Exclusive TWINCUT insert design offers round, 8, and 12 cutting edges for high production milling applications • Cartridge design interchangeable with other LMT Multi-Mills • Available in coarse and fine pitch See page 8 for Inserts.
Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼" to 1.5". The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition.
A Bond ball mill work index is then performed on the mill product for the design of SAG-ball mill circuits. This is important because it was found that there was a 1–1.5 kWh/t higher ball mill work index if the –3.35 mm ball mill test feed size is obtained by SAG mill grinding compared with crushing.
