what is the size and function of cement mill
VRM vs Ball Mill for Cement Grinding Page 1 of 1 nbsp 0183 32 VRM has less flexibility in controlling particle size distribution Overall ball miil is good option for Cement mill but only has limitations for higher capacity as two ball mill to be installed for One VRM but in case of breakdown one ball mill can be in operation Trust this clear your clarifications on equipment selection forRaw Mill In Cement Plant,Cement Making Plant The cement production starts from blasting low and highgrade marl and limestone in the quarry After that, the material, which has the granulation up to 800 mm, is transported by dumper trucks to the hammer crusher where after crushing the particle size for marl is 080 mm and for limestone is 050 mmwhat is the size and function of cement mill
