The vertical roller mill (VRM) which has gained wide acceptance in the cement industry and is used for grinding raw materials (mainly limestone), is a promising alternative.

limestone has an excessive water adsorbtion and separate grinding (ball mill and mixing equipment) is favoured.4 The production of PLC with a Vertical Roller Mill (VRM) is advantageous. A comparison of two ce-ments (CEM II/A-LL 42.5), one ground with a VRM and the other with a ball mill, shows a good perfor-mance of the VRM.

The dry vertical roller mill (VRM) is a novel grinding technology that dries, grinds and classifies ore within a single unit. Testwork was conducted using a pilot-scale Loesche VRM to ... limestone to 85% passing 45 µm and resulted in a circuit specific energy of 15.4 kWh/t (compared to 13.7 kWh/t from the dry Loesche VRM testwork).

The common intergrinding of limestone and clinker in classical ball mills is therefore producing a cement of very high surface area. The higher the limestone content, the higher the negative impact of its surface area on water demand and powder flowability. The intergrinding of Portland-Limestone Cement (PLC) with Vertical Roller Mills avoids ...

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.
