Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
rence of particle crushing implies that the material being tested or being subjected to geotechnical loads is actually changing The changes are irreversible and uncontrolla bleso thatthe material thatexists at theend of a piledriv ing exercise is quite diŠerent from the material that was there to begin with and the properties of the material will
·In this study five materials with different hardness values ranging from 100 − 700 HV 30 are selected to investigate a wide spectrum of metallic materials These selected materials and the respective load levels are highlighted as circles in Fig with this the degree of penetration at which the different abrasion modes are experienced is shown in Fig 2
