Increasing Output Of Cement Grinding In Ball Mill-Case Study
Shree Cement / Suratgarh are operating a semi-finish grinding system type “S” which consists of a roller press
below the V-Separator. The Static- Separator is directly connected to the air inlet spiral of the SKS- Separator. The ball mill
discharge is feed to the top of the SKS-Separator. Cement grinding capacity of Ball mill increases by adjustment of air gap in
the V- Separator with proper air distribution. Maintaining uniform air gap between plates and steps in the V-Separator
increases production of cement mill. To seal air leakage in SKS Separator with uniform air gap increases output of cement
mill. Proper distribution of grinding media with appropriate sizes also enhanced productivity of cement mill.
Target- To increase the TPH from 190 to 220 TPH (PPC) with maintaining quality parameter i.e. 8% residue on +45 micron
and Blaine of 340m2/Kg
