Grinding plays an important role in the beneficiation process. Different grinding media can determine the size distribution, shape, and even the surface grinding limestone (and other raw materials to achieve the right chemical composition) to about 90% passing 90 μm in a dry circuit, making cement by the Cement grinding optimisation ScienceDirect

The consumption of grinding media has been studied extensively in the mineral process industries, where steel balls and rods are mostly used to reduce rock Grindability of a 95/5 OPC at various Blaine fineness: o 27-32 kWh/t at 3,000 cm²/g. o 39-47 kWh/t at 4,000 cm²/g. o 58-69 kWh/t at 5,000 cm²/g. Every 100 cm²/g increase in cement fineness increases the mill power consumption by 1-2 kWh/t for a closed circuit mill & 2-3 kWh/t for an open circuit mill, a sheer waste if this is not requiredImprovements in New & Existing Cement Grinding Mills by Tim

Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits At the second and third stages, grinding balls with diameter of 15 to 100 mm are used as a grinding tool. According to VNTP 06-91 (Departmental Norms of Production Engineering) [], the rates of consumption of grinding balls during the production of 1 t of cement were specified, including for the first chamber of the mill, consumption Efficiency of Using Small Diameter Grinding Balls for Cement Grinding
