Aug 26, 2017· 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 .
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
An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag ® ball mill on grinding and classification performance of a hybrid high pressure grinding roll (HPGR)/multi-compartment ball mill cement grinding circuit. Mass balance of the circuit was done by JKSimMet Steady State ...
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.
