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)/multicompartment ball mill cement grinding circuit. Mass balance of the circuit was done by JKSimMet Steady State ...
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 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

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 ...
Jun 01, 2012· Dynamic Engineering can design kibble systems to suit our client''s unique mining operation. After being mined, mills use small steel balls to grind ore smaller for further processing and to load and unload these steel balls, a kibble system is used.
Sep 10, 2014· The measured stress ranges at the toes of the welds at the cantocan flange in the Antamina ball mills were slightly higher than those obtained from the "standard" finite element analysis that was undertaken during the design of the mill. The difference between the measured stresses at Telfer and Antamina is that the liners in the Telfer ...
Oct 15, 2018· The dynamic analysis of the charge inside the ball was done using Discrete element, EDEM software which resulted in the time varying load applied on the drum. This load was then applied to the FE model using ANSYS software for dynamic analysis of the ball mill structure. The ball mill was modeled in Autodesk Inventor 17.
