CEMENT SikaGrind® FOR VERTICAL ROLLER MILLS
The production of Portland Cement (OPC, CEM I) with Vertical Roller Mills can demand the following benefits from a Grinding Aid: ́ Increased production rate, energy saving ́ The vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the benefits of simple structure and low cost of manufacture and use. Vertical roller mills have many different forms, but they work basically the same. All of these forms come with a roller (or the equivalent of roller grinding parts), and roller along the track of the disc at the Vertical roller mill

Loesche vertical roller mills for the comminution of ores and minerals
Abstract. LOESCHE vertical roller mills are widely used for the comminution of raw materials in the cement industry, for the comminution of clinker and blast furnace slag and for the production of pulverized coal for cement kilns, blast furnaces and power plants. Recent research has shown, that the application of these vertical to simulate vertical roller mills in cement clinker and coal grinding lines. The results show that materials are crushed in more than one stage under the vertical roller mill (Wang et al. 2009;(PDF) An approach to measuring and modelling the residence time
