Peter del Strother, in Lea's Chemistry of Cement and Concrete (Fifth Edition), 2019. The Performance of Ball Mill Relative to Vertical Mills. Comminution in ball mills and vertical mills differs fundamentally. In a ball mill, size reduction takes place by impact and attrition.
Cement Mills. Cement is manufactured by fine grinding the clinker together with various additives. There are a total of 4 Ball Mills for the cement grinding process. The Cement Mills utilize Roller Press as pregrinders with additional Grit Separator for line 2. The total maximum grinding capacity is million tons of cement per year.
