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.
·The three typical failure modes are normal tensile fracture NTF longitudinal shear fracture LSF transverse shear facture TSF The schematic of the fracture surfaces reveals the location of crack nucleation site and the fatigue crack propagation zone It shows that the NTF fracture mode is driven by the normal tensile stress Mode I
·Jaw crusher is the key crusher equipment for stone crushing production Many customers will meet various kinds of fault problems during production process which will affect the whole production schedule Here Luoyang Dahua summarizes the common failure and treatment of the jaw crusher main engine stops suddenly Failure cause

·In this article we report the outcome of an investigation made to uncover the premature fracture of crusher jaws produced in a local foundry A crusher jaw that had failed while in service was studied through metallographic techniques to determine the cause of the failure Our investigation revealed that the reason for the fracture was the presence of large carbides
The phenomenon about fracture of double rotor was observed spottily The fracture was found to be compound cleavage and Intergranular fracture by means of LOM SEM and heat treatment instrument There were massive free ferrite and widmanstatten structure in big cleavage plane The experimental analyses results showed that the reason of fracture failure was that because
·The study revealed that the failure of locally produced crusher jaws was not due to wrong chemical composition but to the precipitation of carbides at grain boundaries and in grains This led to the formation of microcracks and their propagation under impact action of crushing which effectually led to early brittle fracture failure
·During the operation of a forage crusher the common issues usually faced are shorter mean time between failures and low reliability The hammer rotor a critical component is prone to fatigue fracture hammer wear violent vibration of the rotor system caused by uneven wear of the hammers and other issues that reduce the machine s service life and reliability In
·Shortly after the start up of the loaded gyratory crusher a severe failure issue occurred in the eccentric bushing of the crusher Based on the analysis of working conditions and force the failure mechanism of the eccentric bushing is studied in detail by combining macroscopic analysis finite element analysis scanning electron microscopy SEM and
·The fracture failure associated with compression crushing led to the production of less amorphous concrete fines with ∼45% higher quartz content Te study on the hammer crusher based on the
·Abstract Analytical method for determining the energy power parameters of the crushing process in a rotary hammer crusher with a grate is proposed Using the method of equivalent power required for the electric motor drive of the crushing machine at the steady mode of operation and basic laws of general mechanics we explain the following the dependences

The failure investigations of worn hammer surfaces and examination of barite rocks have been conducted to identify the failure mechanisms the nipping behavior and fracture mechanics of
Furthermore as hammer speed is increased the nipping behavior and fracture mechanics of materials are not considerably improved but rather the hammers are subjected to abrasive and fatigue wear
·slag The Hammer crusher wears out which causes its service life not to match its ideal use The purpose of this study is to determine the cause of the failure of the hammer crusher to know the mechanism of the failure of the hammer crusher and to find the solution for the failure of the hammer crusher
·Figure 3 shows a detailed view of the fracture surface of the failed hammer The general morphology of the fracture surface suggested that the hammer had undergone a brittle Further radial marks were seen to be originating from the internal surface of the pinhole diameter thus confirming that the hammer had undergone a brittle failure
These also cause the failure of the hammer crusher 4 Parts wear and deformation The coal hammer crusher operates for a long time the parts are easy to wear and deformation Individual parts may be shaken off crack or even damage When the fatigue limit is reached it may occur damage or even fracture
