A virtual crushing platform can not only be used for understanding but also for development of new crushers and for optimisation purposes. Rock particles are modelled using the bonded particle model (BPM) and laboratory single particle breakage tests have been used for calibration. ... The crusher has been simulated as a quarter section with a ...

A model of crusher performance using single particle breakage data has been developed (Awachie, 1983). Further work to incorporate ore-specific breakage characteristics and the effects of operating variables such as closed side setting, throughput and coarseness of' feed on crusher performance are in progress ( Narayanan, 1986; …

In this paper a cone crusher is modelled and simulated using DEM in the commercial software EDEM® provided by DEM-Solutions Ltd. Cone crushers and gyratory crushers have previously been the subject for DEM modelling and simulation. Lichter et al. (2009) successfully modelled a laboratory B90 cone crusher.

uses a Particle Replacement Model (PRM) embedded in the software EDEMfi 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.

The ExDWT approach to testing the competence of rock particles estimates the benchmark A × b value using data from a large number of individual particles and the newly proposed concept of a t n -family per particle. This contrasts with the standard JKDWT method which fits the model to 15 data points, each one being the average …

Quist and Evertsson [19] made a model of rock agglomerate by BPM and calibrated it by conducting an experiment of breaking a single particle in a laboratory to obtain the size distribution of ...

The development of a gyratory crusher model was achieved in the following three main stages: mathematical representation and coding of the crushing process; …

DEM models including breakage are capable of simulating industrial scale crushers. Compression and impact crushers can be investigated in detail using these models. Breakage and flow are analysed in twin roll and cone crushers. Crushing behaviour in a VSI involves multiple mechanisms of impact breakage.

The combination of this 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 ...

The minimum size of the particles that undergo breakage is assumed to be a function of the impact energy and the feed rate. The model predictions are compared with experimental data obtained for limestone treated in a pilot-plant hammer crusher. The dependence of the product size distribution on the rotor velocity is investigated.

This paper reports the calibration and validation of a cone crusher model using industrial. data. Usually, there ar e three calibration parameters in the condensed breakage function; by contrast ...

Single-particle breakage test is becoming increasingly popular, as researchers seek to understand fracture response that is purely a function of the material being tested, instead of that which is based on the performance of the comminution device being used. To that end, an empirical breakage probability model that builds on …

A discrete element method (DEM) model of the crushing process of a toothed double-roll crusher (TDRC) is established using the bonded particle model. DEM results and experimental data are compared quantitatively and a relatively good agreement is observed. The effects of rotation speed and structure of crushing rolls on …

An improved approach is presented to model the product particle size distribution resulting from grinding in high-pressure roll crusher with the aim to be used in standard high-pressure grinding rolls (HPGR). This approach uses different breakage distribution function parameter values for a single particle compression condition and a …

The work shows the application of a novel breakage model fitted using single-particle breakage information and polyhedral particles to simulate a laboratory …

Size reduction models of cone and impact crushers have been developed using Whiten's generic computational structure for the description of crushers. They incorporate a laboratory single particle breakage test and the t-family of curves to describe the breakage behaviour of the feed ore. A quantitative model of 7-foot cone crushers has been …
