Modelling and Simulation of Dynamic Behaviour in Crushing ...

The main hypothesis in this research is that crushing plants are affected by both gradual and discrete changes in the process which alter the performance of the entire system, making it dynamic. A dynamic simulation is defined here as continuous simulations with sets of differential equations to reproduce the dynamic behaviour of a system.

The invention relates to a system and a method for breaking rocks on a laboratory scale in order to simulate the specific energy consumption in kWh/ton (power/mass flow) of the rocks in a grinder or crusher. This system uses the mechanisms of impact and abrasion for braking the rocks, using wear-resistant materials, without needing to adjust or exchange any parts for a minimum duration of 1000 ...

Jun 12, 2018· The rock that is extracted from quarries is in large chunks, and so the first step in processing it is putting the rock that has been extracted from the ground through stone crushing equipment. This creates pieces of rock that are easier to process. Often this crusher leads the rock, by conveyor belt, to another crusher.
