Vertical roller mills1.25 . VERTICAL ROLLER MILLS I The first LM63.33 by Dr Daniel Strohmeyer, Loesche , Germany Figure 1 working principle of Loesche cement and slag mills 1The assumption for the grindability for the clinker was approximately 15kWht making this material of comparitively good grindability.
Bond Grindability Test Procedure. The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured. Get price
Mar 10, 2015 The vertical roller mill equipped with an internal classifier is often said to be more energy efficient than tumbling mills working on the same material and the same size step e.g. Gerold et al., 2012. It is long established in the cement industry and gains more and more importance in the industrial mineral and iron ore sectors.
When the material is easy to grind, the filling rate can be increased in order to increase the output but when the material is poor in grindability, the filling rate cannot be increased in pursuit of output, especially in the forging warehouse, which will reduce the grinding efficiency.

Central grinding plant for lignite brown coal dust Schwarze Pumpe, Senftenberg, Germany, 1997 We have been successfully involved in the processing and grinding of solid fuels since 1925, with the main emphasis being on coal. Loesche technology always one step ahead 2
For the Zeisel and Hardgrove grindability tests, the feed sample with its precisely defined particle size is crushed by pressure and friction between a grinding bowl and grinding balls. The exerted stress corresponds to that in vertical roller mills.
