Having a high percentage of coarse clinker can be difficult to grind. However, having a high percentage of fine clinker can also be hard to grind and have a negative impact on cement performance.
Read More2020-9-2 affected. In particular, cement production in Spain decreased by 23% in 2008 relative to 2007.1 Due to this huge drop and the forecast for the coming years, cement producers feel obliged to take measures to drastically reduce production costs. One of the fields most affected by these cost-reducing measures is the grinding aids sector, which has ...
