Principle. Ball mill principle work on Impact and Attrition. Both are responsible for size reduction, rapidly moving balls are used for reducing the size of brittle materials. Impact: Impact mean pressure exerted by two heavy objects. Attrition: Reduced the size of the materials when they colloid by heavy weight (Ball).
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.
ii ABSTRACT The application of High Pressure Grinding Roll (HPGR) in comminution circuits is well established in processing cement, diamonds and iron ore.
A total of 120 t of Cristalino ore was prepared and sent to CIMM, where it was crushed and screened prior to grinding tests. The processing equipment included a m (8′) diameter by m (2′) length AG/SAG mill equipped with a 20 kW motor, a cone crusher, a m (3′) diameter by m (4′) length ball mill equipped with a 15 kW ...
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 named "conscious laboratory (CL)".
This plant has 2 lines for cement production (5300 t/d). The ball mill has one component, m diameter, and m length with 240 t/h capacity (made by PSP Company from Přerov, Czechia). The mill's rotation speeds are mainly constant (14 rpm), and there is approximately a fixed oneyear period of changing liners.
