Spring loaded crushers with adjustable jaw settings minimize energy losses due to over crushing Improved Product Quality Controlled crushing action produces consistent particle size and
The rock particles are modelled using the Bonded Particle Model BPM and particle shapes are based on 3D scanned rocks The machine geometry is based on CAD modelling and 3D
The BPM method has previously been applied for modelling of breakage in cone crushers by the authors in a series of publications Johansson et al 2015 Quist and
Working Principle Crawler type mobile multi cylinder cone crushers produce excellent particle shape in the crushed products By utilizing a specially designed crushing chamber based on
Cone crushers are widely used in the mining and aggregates industry to crush blasted rock material The chamber geometry is one of the key factors that influences the cone
Cone crushers are used by both aggregate producers and the mining industry The purpose of using crushers is to reduce the particle size of rock materials or to liberate
DEM simulation of lab scale cone crushers has been reported by Herbst and Potapov 2004 Quist and Evertsson 2010 Single particle breakage in jaw crushers has been
There are numerous methods for determining particle shape European standards such as the EN 933 3 flakiness index and EN 933 4 shape index are often used
The literature reports that the wear on and setting of a cone crusher influence particle shape The fact that wear on and the setting of a cone crusher influence particle shape is considered

Previous work has been carried out by Evertsson 1995 1998 1999 on flow and capacity modelling of cone crushers A particle flow model has been implemented for the jaw
There are numerous methods for determining particle shape European standards such as the EN 933 3 flakiness index and EN 933 4 shape index are often used
Depending on the particle shape the product of a cone crusher can be classified into cubic particles and flaky particles One kind of particle shape of the crushing product is not
An approach that is far more practical in simulating cone crushers is to use particle replacement schemes in which particles within a DEM simulation are replaced
The rock particles are modelled using the Bonded Particle Model BPM and particle shapes are based on 3D scanned rocks The machine geometry is based on CAD
