Better and cheaper cement: Optimising the right clinker …
Dusty clinker can also have poor grindability and a higher kWh/t demand and can cause severe vibration and quality problems when vertical roller mills are used to grind clinker. Keeping clinker dust levels as low as possible (Figure 3) has many benefits to cooler, kiln and downstream plant performance.

Energy efficiency in clinker production
It covers from mill internals to the use of grinding aids. 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.
