Energy efficiency of cement finish grinding in a dry batch

3/1/2006· Dry grinding experiments on cement clinker were carried out using a laboratory batch ball mill equipped with torque measurement. The specific energy was found to be dependent on operating parameters and clinker environment. Additional compounds such as gypsum and pozzolanic tuff improve energy efficiency.

Best energy consumption International Cement Review

Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill

Making Your Cement Grinding Plant Energy Saving

At present, some small and medium-sized cement plants still adopt traditional cement ball mill to grind cement. While both traditional ball mill and cement separator have the disadvantages of high energy consumption and low capacity. Although some enterprises have used the new dry production process, there are still problems in the grinding

Cement mill Wikipedia

The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half that of a ball mill. However, the narrowness of the particle size distribution of the cement is problematic, and the process has yet

Energy Use of Fine Grinding in Mineral Processing

12/18/2013· This quantity is small compared to the power used by a semi-autogenous mill and a ball mill in a primary grinding circuit; a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW. However, the energy used for fine grinding is still significant.
