The one of main problem in cement industry is the continouse abrasion in lining plates of cement mill as a result of impact, abrasive and erosion by steel balls grinding media inside cement mill.

Geometric Design of Tumbling Mill Lifter Bars 881 In particular, the depth of the mill is 15cm and the mill only ﬁlled with spherical charge particles.

The CRITICAL SPEED is the maximum revolutions per minute that the mill can revolve and still maintain performance. Naturally, the opposite is true as well, if the speed, is too slow the material will cascade too soon losing both impact energy and grinding motion.

The cost of mill relining and the influence of the liner profiles on mill performance provide a strong motivation to improve liner selection. However, the capability to predict liner life and progressive profile is poorly developed in the industry.

The ball mill considered in this pilot study is a tumbling mill with a diameter of 90 cm fitted with eight lifters (Fig. 2). This study investigates the effect of the lifter geometry on the distribution of the estimated normal and shear energies in addition to the power draw of the mill.

Thus a typical tumbling mill calculation would require a million frames. In each frame, the first task is to search for contacts between different objects initially set in the code. In the current GPU code, the objects are cylinder, lifter bars, spheres (balls) and end plates.

Computational demands and the lack of detailed experimental verification have limited the value of distinct element method (DEM) modelling approaches in mill simulation studies. This paper presents the results of a study in which the deflection of a lifter bar in a pilot ball mill is measured by an embedded strain gauge sensor and compared […]
