It is known that discrete-element method (DEM) modelling of rock size reduction can be achieved using two approaches – the population balance model (PBM) and the bonded particle model (BPM). However, only the PBM has been successfully used in DEM modelling of a cone crusher in the literature. The aim of this paper is to explore the feasibility of using the …
In this paper, the geometry model and operating conditions are obtained from an industrial-scale impact crusher (PF2020 impact crusher) designed by Sinoma International Intelligent Technology Co., Ltd., which is used for crushing the limestone.

The Whiten crusher model, originally developed for cone crushers, has served as the basis of several approaches to model VSI crushers. In the present work, ... In contrast, the VSI crusher can produce more cubic particles [1–6] but with large amounts of stone powder [1–3]. Many researchers have addressed the performances of the two crushers ...
Quist and Evertsson [11] modeled a discrete element model of the hydraulic cone crusher using the bonded particle model (BPM) in the commercial software EDEM (2018, DEM Solutions, Edinburgh ...
Compressive crushing has been proven to be the most energy efficient way of mechanically reducing the size of rock particles. Cone crushers utilize this mechanism and are the most …
This model will select a suitable crusher that will match the resulting muck-pile particle distribution, thereby eliminating mismatches in crushers in quarries. During quarry design, most of the crushers selected at this stage are not appropriate for the muck-pile size ranges produced after rock fragmentation.
The discrete element method (DEM) analysis model of ore particle and gyratory crusher is established, where ore particle crushing is realized based on the Ab-t 10 breakage model, and its validity is verified based on actual working conditions. On this basis, the performance of the gyratory crusher under different crushing chamber shapes is ...
better particle shape. Single particle breakage requires lower crushing force compared to interparticle. If the crushing angle is small you can experience packing even at low power …
Li et al. (2014) developed a PFC model of coarse size spherical feed in a batch, lab-scale, simplified cone crusher geometry which also used a particle replacement model for the breakage. The effect of varying the closed-side setting and angular speed on the predicted degree of size reduction qualitatively agreed with experimental trends but ...
An empirical model of a crusher was developed which links the product size distribution and the shape of the particles to operating parameters. The simulator produced trends which were similar to the full-scale data. ... This work has presented a method for adapting experimental data to a cone crusher model in order to predict particle shape as ...

Two DEM simulations have been performed where a quarter-section of the crusher is fed by a batch of feed particles. The first one at CSS 34 mm did not perform a good enough quality for
The breakage model implemented in version 4.3 of Rocky DEM, hereby called "Tavares model", describes body breakage of convex polyhedral particles when subjected to stresses of varied magnitudes [22,23,24,25].This model takes into account the energy dissipated in the contact between two elements to decide whether the particle will break or not.
There are mainly three different approaches for modelling the rock material breakage in DEM. The most commonly used is based on a population balance replacement …

The present work uses a Particle Replacement Model (PRM) embedded in the software EDEM® to model and simulate operation of a laboratory-scale jaw crusher. The PRM was calibrated using data from single particle slow compression tests, whereas simulations of the jaw crusher were validated on the basis of experiments, with very good agreement.
