Abstract. In this study, an analytical perspective is used to develop a fundamental model of a jaw crusher. Previously, jaw crushers were modelled in regard to certain aspects, for example, energy consumption (Legendre and Zevenhoven, 2014) or kinematics (Oduori et al., 2015). Approaches to date have been mainly property specific.

A gyratory crusher is a key mineral processing asset in a comminution circuit. Monitoring and predicting the crusher liner wear is essential to ensure the throughput and product quality are maintained during production. This study developed a digital sensor and a discrete element modelling (DEM)-coupled methodology to monitor …

Specifically, ring hammer crushers are widely equipped with coal conveying systems in power plants [20]. In [21], the specific net energy model of ring hammer crushers is constructed. For simplicity, the specific net impact energy model from [21] is adopted in this work to derive the mechanical power of the ring hammer crusher, as (3) …

This model considers empirical blasting and the breakage function of cone crushers, along with a probability model of vibrating screens, and is delivered as a …

For comparison, when the model of Whiten and White (1979) is used for simulation of the behaviour of short-head cone crushers, the values for φ, m and l are often fixed to 0.2, 0.5 and 2.5 respectively. A greater value for the fine fraction φ in our case reflects the well-known fact that the product issued from impact crushing contains more …

The FE model was developed to observe the stresses and deflections which are caused while crushing. Various iterations are performed and graphs are plotted and analyzed to …

In this paper, a DEM. model was applied to a copper mining gyratory crusher to perform a comprehensive analysis of. the loads in the mantle, the crushing torque, and crushing power. A novel polar ...

Several mathematical models for the VSI crusher have been proposed in the last two decades or so. 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, the Andersen/Awachie/Whiten model has been used as the basis for …

Geology. 2011. TLDR. The data obtained by applying impact pendulum testing to single limestone particles were processed in order to obtain the performance models of the principal parameters of fragmentation function, thereby reducing the number of experiments necessary to model the impact crushing process.

Innovation has an important role in improving the productivity, safety and sustainability of mining operations. Historically, ore transport was done by diesel trucks, but with the commitment to reduce CO2 emissions and increase mine safety, mining companies have invested in innovative, more sustainable ore transport technologies. The innovative …

The paper shows the preparation of the numerical models necessary for the simulation mapping of industrial-scale crushers of problematic material, such as copper ore with complex lithology. The …

The objectives of this work are to analyze fragmentation performance, predict fragment size, rate the quality in relation to the gape of the crusher, and develop …

The SEM Model 0101 Hard Drive Crusher has been evaluated by the NSA/CSS and meets NSA and DoD compliance guidelines for the physical damage of media with a throughput rating of up to 204 drives/hour. This hard drive crusher destroys all hard drives regardless of size, format, or type up to 1.85″ high including desktop, laptop, and server drives.

The simulated operating parameters show some agreement with measured data, but the crusher was not run under ideal conditions at all times. ... scale crusher. This model has been implemented in a ...

Compressive crushing has been proven to be one of the most energy efficient principles for breaking rock particles (Schönert, 1979). In this paper the cone crusher, which utilizes this mechanism, is investigated using the discrete element method (DEM) and industrial scale experiments. The purpose of the work is to develop a virtual simulation environment that …

Comparisons between model and real crusher reflects the change from new liners until 73 h of operation. If the wear is computed in the direction normal to the liner surface and plotted against local y-coordinate in the crusher, we can see the agreement between simulation and measurements in Fig. 8. Fig. 9 shows measured and simulated …

The principle of phase transformation in ultra-high strength steel for cone crusher was studied by DIL805 thermal mechanical simulate, and the critical temperature was determined.

Abstract. Cone crushers are used in the aggregates and mining industries to crush rock material. A model to predict the worn geometry of cone crushers was previously developed. In that model there was some disagreements between predicted and measured geometry and several effects were suggested to explain the discrepancy in …

Crushers. Purpose. The purpose of the Rock Crusher model is to visualize ALL the work required to go from "concept to cash," not just the work of coding. Often the work required to learn precisely what to build is invisible and therefore unmanaged. A Crusher is a backlog item (or Rock, in this metaphor), that makes learning "precisely ...
