Snapshot of DEM simulations of vertical stirred mill charged with 86.8 kg of 20 mm grinding media and screw shaft rotating at 3 m/s (a), 2.5 m/s (b) and 2.0 m/s (c). Grinding media are colored by their velocity. The collision energy spectra of the mill can be observed in Fig. 5, showing the normal, tangential and the total energy dissipatedFor a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.Cement grinding Vertical roller mills VS ball mills

Difference between a Cement Ball Mill and Vertical Cement Mill
While a ball mill is suitable for grinding all kinds of cement clinker and other materials, a vertical cement mill is more suitable for grinding raw materials and cement clinker. Choosing the right type of mill depends on the specific needs of your operation, including your production capacity, energy consumption, maintenance requirements, and cost Introduction. The TowerMill® was developed in Japan in the 1950s, by the Tower Mill Kubota Corporation, for applications in fine and ultrafine grinding, and it was the first vertical mill used in the mineral industry (Stief et al., 1987).The Vertimill™, manufactured by TON has basically the same principle of operation and was introduced Vertical Agitated Media Mill scale-up and simulation
