Dynamic crushing of cellular materials: A unique

2016-9-1  For example, Zheng et al. (2014) reported the quasi-static and dynamic initial crushing stresses of cellular materials are different due to different deformation mechanisms, but Barnes et al. (2014) regarded that the stress ahead of the shock front is at the same level as the first local stress maximum of the quasi-static stress-strain curve. These investigations are based on the assumption of the shock-like deformation patterns, which may be improper for some impact cases, and the shock ...

2012-2-24  1 Crushing of hard Materials 1.1 Processes used for crushing hard materials These processes are used to reduce a material from its original size to a smaller, defined output size. The main physical size reduction processes are: shattering (breaking), squeezing, grinding. Shattering (breaking) is used, as a rule, to reduce materials with grain sizes of > 50 mm in size.

2020-3-15  The importance of crushing in sands for example has long been acknowledged; when a sand is subjected to monotonic increasing stress (normal compression), it is well known that after a high enough stress is reached, particle crushing begins and causes a permanent decrease in volume (e.g. Nakata et al., 2001). Particle crushing also has a direct influence on the dilatancy of sand when

Secondary crushing. The purpose of intermediate crushing is to produce various coarser fractions or to prepare material for final crushing. If the intermediate crusher is used to make railway ballast, product quality is important. In other cases, there are normally no quality requirements, although the product must be suitable for fine crushing.
