Back-calculation of particle fracture energies using data

Apr 01, 2020· 1. Introduction. Single particle impact breakage tests have been used consistently for nearly 40 years (Awachie, 1983) to characterise materials for modelling crushers and mills.These tests were originally proposed to decouple material-specific properties from machine-specific properties, which are invariably combined in standard laboratory crushing and grinding tests which became the norm in

(PDF) New developments in cone crusher performance

The combination of this Process optimization breakage model with DEM has therefore allowed the development of a multi physics based comminution model that can be applied to crusher development. This model is sensitive to all aspects of crusher design including crusher machine parameters and the ore characteristics.

Investigation of High Speed Cone Crushing Using Laboratory

Image of the Morgårdshammar B90 laboratory cone crusher Material The material used in the laboratory experiments is a granite rock type from Kållered, Sweden. Characterization of material parameters for this material has previously been done by Quist (2012). The BPM has been calibrated against single particle breakage laboratory experiments.

Gyratory crusher model and impact parameters related to

The objective of this research was to develop a mathematical model for gyratory crushers to help in the prediction of energy consumption and to analyze dominant parameters that affect this energy consumption. The development of a gyratory crusher model was achieved in the following three main stages: mathematical representation and coding of the crushing process; building an amperage

Cone crusher performance evaluation using DEM simulations

Cone crushers are commonly used for secondary and tertiary crushing stages in the aggregate and mining industry. It has previously been demonstrated that the discrete element method (DEM) can be used to simulate rock breakage in crushers using a variety of modelling techniques. In order to provide confidence in the simulation results the DEM models need to be validated against experimental data.

Jul 15, 2018· In the case of impact crushers Djordjevic and Shi [9] as well as Schubert [10] have simulated a horizontal impact crusher using the BPM approach. However in both cases relatively few particles have been used and the geometries are very simplified. A DEM model for simulating rock breakage in cone crushers has been presented by Lichter and Lim [8].
