The hammer crusher always works under heavy load, discontinuous and impact working condition, which is complex, especially when impact happens. The spindle is one of the most important parts of the hammer crusher, the performance of which has a great effect on the whole structure. This paper discussed the main loads acting on the spindle. After the multibody system dynamics (MBD) models .

· A dynamic simulation model of a ring die pellet mill with eccentricity was developed in LSDYNA software, and the internal stress distribution of biomass was calculated. The obtained results revealed that the internal stress on biomass and the angle of extrusion both gradually decreased with the increasing distance between ring die and roller. The relationship between distance and extrusion ...
· Finally, based on the iron ore coarsely crushed by the gyratory crusher, the dynamic characteristics of the C900 cone crusher were simulated by using the discrete element method (DEM), and the simulation results are basically consistent with the numerical analysis results. Results show that considering the amount of ore uplift in the blockage layer, the revised mathematical model of crusher ...

behaviour of soil particles subject to dynamic loading conditions1. Mishra and Rajamani pioneered the appliion of DEM to grinding mills and demonstrated that despite the fact that the DEM simulations are based on two dimensions (2D), the technique is able to predict the power draw of mills with reasonable accuracy over a wide range of mill diameters2,3. More than 10 .
· · Dynamic model of a cone crusher. A generic simulation model for a control system design of a cone crusher is presented in Fig. 3. The model consists of eight individual submodels for actuators, material and feedhopper flows, crusher dynamics, and crusher performance models divided to product size, capacity, and power models.

The comminution of rock and ore materials consumes ~ % of the total energy production in mining intensive countries (Tromans, 2008). Several research findings show that there are ways of utilizing compressive breakage modes that are more energy efficient compared to conventional grinding circuits based on large inefficient tumbling mills. Circuits using Cone Crushers and High Pressure ...
dynamic structural deformation is about 750 mm. At the moment of separation from the barrier the deflection of the vehicle is about 675 mm. The measured static residual crush is about 490 mm. This difference between crush at separation and residual crush has been observed in numerous other frontal barrier tests and indies that vehicle structures
