Abstract. Crushing is a substantial process step for the following separation, as it transfers the battery cells or modules to a storable and conveyable bulk material. Crushing also leads to the opening of the battery cells and release of valuable materials. Because of the deliberate destruction of the battery cells, this process has a high ...

Impact crushers are traditionally classified into two main types, horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other.

Crushed stone is produced by mechanical processes, where several crushing equipments are utilized in crushing–screening plants [1,2,3,4,5,6,7]. Crushed stones should be distinguished by their highest quality, which should be investigated more profoundly from the point of their roughness, angularity, flakiness, particle size …

The mechanical behaviour of the particle has shown a brittle–ductile transition depending on the loading conditions with respect to confinement. (ii) The lateral constraint increases the initial stiffness and the maximum breakage strength of the particle. (iii) Three crack types are observed: the primary, the secondary and the tertiary cracks.
