A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Read MoreThe production of cement is complex and requires large amounts of energy. Therefore the design of these powerful plants needs to incorporate simplicity and energy efficiency. This is particularly true for vertical mills as they play an important and critical role in the process with operators calling for bigger and more powerful mills.
Read MoreSep 18, 2013 The cement mill certificate includes three performance tests that merit close attention: false set, Vicat setting time and strength. False set. False set is the tendency for cement mixtures to stiffen early, typically due to the sulfate in the cement reacting with the water to form gypsum crystals over the first few minutes of mixing.
