Manufacturing Of Cement By Dry And Wet Process

2020-2-27 · Storage and Packing: As cement comes out from grinding mills, it is collected in a hopper and taken in bucket elevator for storage in silos. The cement from silos is packed by machines in bags. Each bag of cement contains 50 kg or 0.035 m 3 of cement. Now let’s know the manufacturing of cement by the dry process.
