Cone crushers are like gyratory crushers, except that the outer crushing surface takes the form of an upward-pointing apex, which results in the two crushing surfaces being nearly parallel to each other, as shown in Fig. 1. This design allows the crushed material to spread out as it works its way down while preventing close packing …

Crush testing is widely applied across industries, including packaging, construction, aerospace, automotive, and pharmaceuticals. By understanding how materials respond to compressive forces, engineers and designers can make informed decisions on material selection, product design, quality control, and compliance with international standards.

This paper aims to investigate the applicability of a novel testing method for estimating the compressive strength of in-situ masonry mortar by the crush test method (CTM). …
