Modelling of mill load for wet ball mill via ga control automatico abstractthe load of wet ball mill is a key parameter for grinding process and regression rules from data whose regression theory is to find a nonlinear map
Nov 18 2008 summary the ball mill is designed to grind materials by turning the cylindrical shell with grinding medium eg steel balls put in the shell and has a simple structure and ease of handling furthermore the ball mill of a large capacity has been available to a very extensive range of applications in both dry and wet 14 references 1
The operating principle of the ball mill consists of following steps in a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls
Ball mill can be reorganised as 7 and 8 where bwio and awio are the corrected operating work indices and wagsag wbm are the respective power draw of agsag and ball mills note that the ball mill operating work index is applied only on the portion that needs the additional grinding q2 which renders to the agsag mill the
Iv ball mills ball mills are one of the more mon mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades a typical ball mill has an l d ratio of 151 ball mills are filled with spheres or other shapes made of steel or ceramics or with pebbles made of flint or of an ore being ground
Oct 19 2006 what it is the optimun speed for a ball mill posted in pyrotechnics i have done a ball mill recenly finished but the motor has too rpms is too fast for use in a ball mill the pvc cylinder that i use left of the shafts with the motor i will use a 40 mm pulley because i have a 50 mm driven pulley in one of my two shafts

Get PriceGrinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical mechanical and chemical characteristics typical examples are the various ores minerals limestone etc the applications of ball mills are ubiquitous in mineral
Get PriceThe rate of grinding is not the whole story however for it has been shown from theoretical considerations by rose and from tests on industrial mills by engels that ball and liner wear is reduced by the use of soft metal for the balls and mill shell when very hard materials are to be ground
Get PricePlanetary ball mills are used wherever the highest degree of fineness is addition to wellproven mixing and size reduction processes these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and
Get PriceThe motion of the charge that is the grinding media and the material undergoing grinding within a mill is of considerable theoretical interest and practical importance and for these reasons has been the subject of considerable study by a number of workers but even so no rigid and complete theory covering all the aspects of the dynamics of the mill charge has yet been produced
