This plant has 2 lines for cement production (5300 t/d). The ball mill has one component, 5.20 m diameter, and 11.20 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 one-year period of changing liners.Cement grinding with our highly efficient ball mill. An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance.

V — Effective volume of ball mill, m3; G2 — Material less than 0.074mm in product accounts for the percentage of total material, %; G1 — Material less than 0.074mm in ore feeding accounts for 0.074mm in the percentage of the total material, %; q’m — Unit productivity calculated according to the new generation grade (0.074mm), t/(m3.h). The Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 120mm according to different grinding requirements. In a cement ball mill, generally, φ50–100mm steel balls are used in the coarse grinding chamber, φ20–50mm steel balls are used in the fine grinding chamber. 2.How to choose proper grinding media for your ball mill

A cement Vertical Roller Mill modeling based on the number of breakages. Vertical roller mills (VRM) are widely used to grind, dry, and select powders from various materials in the cement, electric power, metallurgical, chemical, and nonmetallic ore industries. For the sectors above, the VRM is a powerful and energy-intensive grinding The performance of grinding media in a ball mill is also measured in terms of its wear rate.

The better mills on the market have an efficiency of about 8-9 % which means that only 8-9 % of the energy results in grinding and the majority is converted mainly into heat. The ball mill has the worst efficiency of all types of mills on the market. Just 4 % of the energy is used for comminution. Nevertheless when grinding is required the ballA raw mill is a key piece of equipment used in a cement plant to grind raw materials into a fine powder.
