Kiln Control and Operation
1.1 Oxygen control. The oxygen at the calciner outlet is controlled through the calciner draft, in the same way as the oxygen at kiln inlet is controlled by the kiln draft. A normal target value for the oxygen after calciner (bottom cyclone exit) is 1 – 1.5 %.

Machine learning applications and process intelligence for cement
cement industry. 1. Introduction. Cement grinding is a key process in the cement industry. During this phase, gypsum and mineral or artificial raw materials (e.g., pozzolan, ash, limestone) are added to the clinker (basic raw material for cement production) and, then grinded in special mills until a very small grain size is achieved.

What Equipment is Used for Cement Manufacturing?
Because raw coal is still used in cement manufacturing, equipment that can grind coal onsite is necessary for most cement plants. As with the actual milling of cement, manufacturing equipment used to break down the coal requires mechanisms with airlock capabilities. These must be able to handle capacities from 10-100 tons hourly.
