New solution to bring down cement ball mill power consumption-Topnewer CGB Technology. Published on October 28, 2020 October 28, 2020 • 5 Likes • 0 Comments
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
Energy management systems can be improved by using artificial intelligence techniques such as neural networks and genetic algorithms for modelling and optimising equipment and system energy consumption. This paper proposes modelling ball mill consumption as used in the cement industry from field variables. The regression model was …

Ball mills are most commonly used in cement factories to grind the raw material and finely grind the cement. The use of ball mills in cement grinding is due to several factors, among which are relatively simple design and high processing rate. However, these machines have certain limitations as well. It is known that only 2 to 20% of the energy ...
Energy consumption and output. Cement mills are normally driven by electric motors. Modern installations draw power of 2-10 MW. The power (in kW) required to turn a ball mill is approximated by: P = 0.285 d (1.073-j) m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in …
This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system. Capacity of cement mills. The cement mills on a cement plant are usually sized for a clinker consumption considerably greater than the output of the plant's kilns. This is for two reasons:
