Mar 14, 2007 Personal thoughts These machines are vibration sensitive in addition to highly senstive to settlement (even so when it is differential) and deflections which are perfectly normal and acceptable in a typical foundation designed for loads (including simple magnitude based load factors to compensate for dynamic loads) are usually not acceptable.

Jun 19, 2015 The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open closed.
Oct 19, 2016 Ball Mill Concrete Foundations Adequate foundations for any heavy equipment, and in particular grinding mills, are extremely important to assure proper operation. The foundation should preferably be in one piece, that is, with a reinforced slab footing (so called “mat”) extending under both trunnion bearing foundations as well as the pinion bearing foundation.
Mill suppliers do not state the dynamic loads generated by an operating mill, ie drive train and charge related load variations. Such a document may be far simpler to comprehend, however will cause problems when it comes to correctly designing the foundation. Consideration of static x, y, z loads is not enough capacity to accept the dynamic.
