composition 80 clinker, 5 gypsum, 15 limestone, produced with ball mill equipped with high efficiency separator - In steady state and stable conditions of the main parameters controlling the milling operations, cement streams around separator alimentation, reject and fines were sampled.
The chemical, mineralogical and granulometric composition of raw meal considerably influence its burnability and reactivity, which ultimately defines the clinker phases formed in the cement kiln. Moreover, variations in the chemical composition of the raw meal directly affect kiln operation, refractory lining, fuel consumption and clinker quality.
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either
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.
