Ball mill
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints Ball mills rotate around a horizontal axis, partially filled with the materialFor 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 015020 EUR per ton of cement For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, ie whether hardfacing is appliedCement grinding Vertical roller mills VS ball mills
How to choose between ball mill and vertical roller mill?
2022年6月24日· The ball mill has the unique advantage of “the particle shape is approximately spherical, which is conducive to the calcination of raw meal and the hydration and hardening of cement”, which is the main reason why clinker mills still use ball mills 4 Grinding process In the ball mill, the material is mainly crushed by impact and friction2021年1月1日· With the grinding capacity of a vertical roller mill and the ability to dry, grind and sort in a single unit, the vertical roller mill offers a definite advantage over the ball mill system [10] A twocompartment ball mill with a highly efficient separator is still procured for new cement grinding units installation, although the vertical roller mill has now becomeReview on vertical roller mill in cement industry & its performance
OPTIMIZING THE CONTROL SYSTEM OF CEMENT MILLING:
the grinding process remains a challenging issue, due to the elevated degree of uncertainties, process nonlinearity and frequent change of the set points and the respective model parameters during operation For productivity and quality reasons, grinding is mostly performed in closed circuits: The ball cement mill (CM) is fed with raw materials2021年6月10日· In cement mills, ventilation is a critical key for maintaining temperature and material transportation However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today This investigation is going to fill this gap based on a newly developed concept namedVentilation Prediction for an Industrial Cement Raw Ball Mill
