Limestone lumps are ground, classified, and dried in Pfeiffer MPS vertical roller mills. The fineness of pulverized limestone can be set within a wide range ( to mm). If required, classifier grits can be evacuated for another classification in a downstream Pfeiffer separator and separated into limestone sands ( to mm) in ...
Here is how a limestone mill typically operates: Crushing: A crusher or a hammer mill is used to reduce the size of limestone rocks. Grinding: A limestone mill is used to grind the crushed limestone into a fine powder. In this procedure, the mill's grinding rollers and grinding ring crush the limestone powder that was previously fed into it.
The fineness of the white fine limes can be set within wide limits ( to mm). In downstream Pfeiffer lime hydrators, water is added to quicklime, thus transforming it into lime hydrate. White fine lime is used for the production of limestone bricks and aerated concrete. Lime hydrate is used for the production of plaster and mortar.
