Energy efficiency in clinker production

31/07/2017 · A cement clinker is usually ground using a ball mill. This hardware is generally divided into two or three chambers, with different size of grinding media. As the clinker particles are ground further, smaller media are more efficient at reducing the particle size even further. Grinding can be either 'open circuit' or 'closed circuit'.

Open Circuit VS Closed Circuit Ball Mill

02/06/2022 · Generally, the closedcircuit system can increase the output by 1525% than the opencircuit system, and the product fineness can also be controlled by adjusting the classifiion equipment, which is more convenient. With the implementation of the national energysaving and emission reduction policy, the ball mill grinding technology is ...
