This paper explores the effect of particle breakage on mechanical behavior coarse sand through 3D Discrete Element Method (DEM) simulations direct shear tests (DST). The objective is to gain insights into macro- and micro-mechanical behaviors crushable sand, with a particular focus stress–strain relationship, volumetric deformation, evolution grain crushing. involve comparison between non-crush...

Aiming at the lack of a precise discrete element model in simulation analysis corn straw crushing, this paper established bond models with different structure and particle properties based on Hertz-Mindlin bonding, verified by combining physical test optimization design methods. Firstly, study generates bonded bonding for epidermis-epidermis, inner flesh-internal flesh, epidermis-internal respe...

Now crushers are one of the most common types crushing equipment using principle a mechanical method material destruction (for example, rollers, jaws, cone crushers, etc.). To provide effective parameters crusher, it is necessary to take into account correlation between physical and characteristics (sizes, shapes, strengths, fragility, uniformity, etc.) energy crusher (operation power) at desig...

Crushing and screening processes are often regulated using relay-based on/off controls or, when controlled by PID controllers, the control design is limited to a single crusher and its proximity. The design does not necessarily consider process interactions, load disturbances and, in a wider perspective, does not treat a crushing and screening plant as an entity from feeding to product piles. T...
