A Technical and Economic Comparison of Ball Mill Limestone

A pilot-scale Loesche VRM was used to determine the power required to grind 100 t/h of the same limestone as used at Kusile (work index of 12 kWh/t) with a top size of 19 mm to a 85% and 95% passing 45 µm product.

Operational parameters affecting the vertical roller mill

Vertical roller mills (VRM) have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of equipment in 3 Major Limestone Supply Methods for FGD. There are 3 prevailing limestone supply methods for FGD, namely, 1 Outsorced limestone powder for FGD; 2 Self-built dry limestone mills outside the coal-fired power plants; 3 Self-built wet limestone mills inside the coal-fired power plants. For decades, we have been optimizing Suitable FGD limestone mill, low investment in power plants

Limestone Milling Process

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.SikaGrind® FOR VERTICAL ROLLER MILLS 7 SikaGrind® FOR PORTLAND-LIMESTONE CEMENT Limestone is much easier to grind than clinker. The common intergrinding of limestone and clinker in classical ball mills is there-fore producing a cement of very high surface.
