Other designations were also used for the high pressure grinding technology with respect to a wide range of applications from coarse crushing to very fine grinding, such as 'high pressure roller crusher', HPRC. The generic term that has been widely settled upon is HPGR, high pressure grinding rolls, and is used in this paper as well.

A multiscale model for including interstitial powder or fine particles in DEM simulations of grinding mills is proposed. This consists of a traditional DEM model at the macroscale which includes only grinding media and potential coarser fractions of feed and product. Microscale models are embedded within this macroscale model.

Computer simulation developed handinhand with the rapid growth of the computer, following its first largescale deployment during the Manhattan Project in World War II to model the process of nuclear detonation. It was a simulation of 12 hard spheres using a Monte Carlo algorithm.
A high potential to increase the process knowledge and the process optimization is based on modeling and simulation the grinding process. Motivation The grinding process – Finishing manufacturing process to achieve a high product quality and precision – High dimension and form accuracy – High .

Fine Screens General Fine screens shall be preceeded by a trash rack or coarse bar screen. Comminution shall not be used ahead of fine screens. A minimum of two fine screens shall be provided, each capable of independent operation at peak design flow. The design engineer must fully evaluate a proposal where fine screens are
The simulation of the interaction of abrasive grain and workpiece based on numerical models offers a great potential for the analysis of the material removal mechanisms in grinding processes. In comparison to experimental investigations, the processes and state variables can be determined more costeffectively and at higher local and temporal resolutions with numerical simulations.
We offer a vast range of machines designed for comminution technology : from crushers for preliminary comminution to agitated media mills for particle sizes in the nano range. Because our machines are available in many sizes, it is child's play to find the best design for your process.
