the advantages of vertical mills for size reduction are not only their high throughput rates but also the high quality of the final product with respect to particle size and size distribution as well as their energy demand. roller mills are typically used in coal fired power plants and cement plants.
the particle size distribution also benefits from the new grinding aid. the psd becomes broader as shown in the slope according to rrsb the potential for strength development is decreased as the cement psd becomes broader but the workability of mortar and concrete is improved.
flsmidth has supplied the global cement industry with leading vertical roller mill designs for raw, fuel and cement grinding for several decades. the size range of the OK mill includes and roller mills and includes the largest vrm sizes product quality is a function of cement particle size distribution and the

partial replacement of sand with quarry dust in concrete. -the reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in concrete.
In recent days there were also been many attempts to use fly ash, an industrial by product as partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available. this present work is an attempt to use quarry dust as partial replacement for sand in concrete.
