Comparison of Roller Press and VRM for slag grinding, Stefan Seemann, KHD. Presentation given at the Global Slag Conference 2017 on 18 - 19 May 2017.
Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time delay characteristics also dynamics changes within 2-4 minutes. The fast dynamics necessitate closer attention to the
In roller press, the contact area between the two rollers and the material is small; the material is ground by only passing through the roller press once due to the large grinding ratio. In a vertical mill, there generally are two or more grinding rollers. The contact area between the grinding roller and the grinding disc is large, and the ...
Kitchenaid Pasta Press Vs Roller. The KitchenAid Pasta Roller (see Amazon) is an incredible attachment that you can use to make various items such as lasagna noodles, tortillas, perogies, and thin-crust pizza dough. It can be attached to the front of the stand mixer when you have the dough ready, and adjust it to different settings.

The table diameter on a VRM varies between 1.5 and 7.5 m. As the net weight of the roller itself is inadequate to generate the necessary grinding pressure, the rollers are exerted by a hydraulic force. The angular velocity of the table exerts sufficient centrifugal force to move the particles towards the table periphery.

The cement roller press has a high energy utilization rate and remarkable energy-saving effect in the material grinding process. In cement plant, cement roller …
It is characteristic of grinding in vertical roller mills that the energy input to the material per pass between roller and table is small, for which reason a large number of passes are required to obtain the necessary specific energy input to the material. This leads to a very high internal material circulation factor. .
similar to roller press, around 20 % less compared to ball mill, but with a moderate circulating load and grinding pressure. This system claims to grind materials having moisture up to 20 %. Thus, in future mainly the VRM, high pressure grinding rolls or Horizontal/ Ring
In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thick-ness of the material bed between roller and table is a multiple of the particle size.
Vertical roller mill reliability and the costs of operation are depending much on the wear parts solution and strategy. The benchmark sets today the roller press technology with better solutions ...
