Concrete Crushing - an overview ScienceDirect Topics

2010-8-7  The desired concrete crushing failures shown in Figs. 1.24 and 1.25 can only be achieved if IC, CDC and PE debonding can be prevented from occurring before the design load to cause concrete crushing. However, this may not always be possible; in which case, it may be necessary to design for either IC or CDC debonding to occur at the design load so that concrete crushing will not occur.

2021-5-24  High-voltage pulse discharge (HVPD) is an energy-saving, efficient, and green technique, which has broad prospects in concrete crushing. The finite element models of the concrete beam, slab, and column segments were established with ANSYS/LS-DYNA finite element software. Based on the principle of equal impact pressure, the shock wave generated by the fuse explosion caused by HVPD

Crushers - an overview ScienceDirect Topics

The crushing force is produced by an eccentric shaft. Then it is transferred to the crushing zone via a toggle plate system and supported by the back wall of the housing of the machine. Spring-pulling rods keep the whole system in a condition of no positive connection. Centrifugal masses on the eccentric shaft serve as compensation for heavy loads.
