For raw material grinding a quadropol® vertical roller mills QMR² 45/23 was contracted to serve the kiln line, while for cement grinding two identical QMC² 45/23 were considered for grinding different cement types. The request for interchangeable parts for the three mills was fulfilled and represents still a holistic approach.
3. Double Position-Limiting Technology Makes Operation More Stable. In the CLUM series ultrafine vertical roller mill, the contact point between roller shell and millstone liner plate adopts electronic limiting technology and mechanical limiting protection technology, which can avoid the destructive impact (e.g. the grinding roller directly smashing the millstone) …

Grinding of clinker is the last and most energy-consuming stage of the cement manufacturing process, drawing on average 40% of the total energy required to produce one ton of cement. During this stage, the clinker particles are substantially reduced in size to generate a certain level of fineness as it has a direct influence on such …
Full-scale closed-circuit cement ball milling was modeled using a true unsteady-state simulator (TUSSIM), based on a transient cell-based population balance model (PBM) with a set of differential algebraic equations (DAEs). As a major novelty, the PBM for the mill was coupled with a dust load-dependent, variable Tromp curve for the …
