A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

Sep 22, 2014· Both gears and pinions on twin ball mills failed almost simultaneously. Our 2001 paper showed that the location of the failures is explained by the shape of the girth gear blanks. Fresko et. al. [2] shows that T-gears are in fact better than Y-gears in terms of load distribution and that the diameter of the pinion in a gear set can result in ...
For a small ball mill, with a mill diameter less than 3.6 m and small dynamic loads, the method of free vibration analysis (also call modal analysis) can be used.
Ball-Mills are the structures used in cement industries. This structures are mainly subjected to Mechanical static, Dynamic & Fatigue loads depending on their service subject. FEA gives better understanding of actual behavior of assembly due to various static, dynamic & fatigue loadings. Girth gear, shell, welds, crusher, foundation are ...
Fig. 1. A typical ball mill motion [2]. design to avoid resonance and gives an idea of how the design will respond to different types of dynamic loads. Ball mill is an example of a machine whose dynamic characteristics can be better studied by modal analysis. Modal analysis since 1960s, has been widely used as an important method in fault ...

How to calculate dynamic load of ball mill he dynamic analysis of ball mill foundation is a typical problem of dynamic loads come from not only the unbalanced forces by mill charge rotation t is not convenient to back-calculate for all of the six parameters in theet price.
For small ball mill, mill diameter less than 3.6 m, with small dynamic loads, the method of free vibration analysis can be used. This is also call modal analysis.
The feed of the ball mill contains grinding balls. In order to effectively reduce the direct impact of materials on the ball mill feed bushing and improve the service life of the ball mill feed bushing, the feeding point of the groove in the feeding part of the ball mill must be as close to the side of the mill barrel as possible.
