The sparse decomposition of vibration signal is the important part of the fault diagnosis of Double Cavity Jaw Crusher. But the calculation count of sparse decomposition is very large, and it is difficult to fulfill signal processing. After analyzing characteristics of Double Cavity Jaw Crusher, this paper proposes applying the hybrid algorithm, DEPSO which mixed the characteristics of particle...

The crushing chamber is the core component of a cone crusher, consisting mantle and concave parts. Reducing impact wear on performance crushers quality crushed products while extending service life has become significant research challenge. compression ratio particle size distribution coefficient pressure investigated here in order to establish model. effect normal tangential components discuss...

This paper presents the characterization of a secondary cone crusher concave liner made Hadfield steel used in Chilean mining after crushing copper minerals during all service life. During use, suffers indentation (cold working) and abrasion; this combination provides with layer that constantly renews itself, maintaining surface highly resistant to abrasive wear. The results presented here were...

Operational variables of a mineral processing circuit are subjected to different variations. Steady-statesimulation of processes provides an estimate of their ideal stable performance whereas their dynamicsimulation predicts the effects of the variations on the processes or their subsequent processes. In thispaper, a dynamic simulator containing some of the major equipment of mineral processing...

A robust controller is developed for the trajectory tracking control of a 6-DOF robotic crusher in task space. Firstly, dynamic model including mantle assembly and actuators derived by Lagrange method according to virtual work principle. In order simulate crushing behavior cone chamber, achieved ADAMS. Then, which contains compensation designed, convergence stability strictly proved based on Ly...
