OR (LAFARGE) 86-92% passing 1 mm, 80-90% passing 0.6 mm, 75-85% passing 0.5mm
Adjusting mill parameters: Fine-tuning mill parameters such as mill speed, ball charge, filling ratio, and grinding media size can have a substantial impact on the grinding efficiency of the mill. For example, a 10% increase in mill speed can result in up to 10% higher production rate, while optimizing the ball charge can lead to a 5-10% ...
The calculation of the thermical balance of the ball mill is now proposed according 2 methods: - The first method, we know the ventilation of the mill + the cement temperature and we want to calculate the water quantity we need to inject in order to get the temperature at mill outlet we would like to have.

Of course, even if we set a more appropriate cement fineness, it is difficult to change the current situation that the flow velocity in the open-circuit ball mill is only 1/2-1/3 of that in the closed-circuit ball mill with the same specification, which will lead to poor comprehensive performance of finished cement, low system output and ...
The grinding process in ball mills and vertical roller mills is fundamentally different [15]. Following are advantages of VRM over Ball Mills with reference to these issues: - • Strong drying ability - Inlet hot air from Kiln can dry materials with 20% water content. (max moisture 20% vs. 3% in ball mill) [15], [16]. •

The use of fossil fuels such as coal, natural gas, and oil is common in cement production, both as a fuel for the kiln and as a source of heat for other parts of the process which leads to CO2 emitted by combustion.However chemical reactions happening in the kiln (calcination) are also responsible for up to 60% of the total of emissions of the ...
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
