Development of a Design Simulator for the Schonert New Technology Comminution Machine: An Industrial-University Cooperative Research Program

It is claimed that a new technology based on compressive crushing of a bed of particles between rollers having a variable gap can lead to significant reduction in the energy required for comminution. This research will measure the breakage kinetics for three types of materials on passing through the rollers and also measure the breakage kinetics in a ball mill of particles prestressed by passage through the rollers. The data required, although highly empirical, is need for the design and optimization of grinding loops. If only 10 percent of the energy consumed in the U.S. on comminution can be saved by this technology, it would be a significant savings.
