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...

Crushers are machines which use a metal surface to break or compress materials mining operations use crushers, commonly classified by the degree to which they fragment the starting material with primary and secondary crushers handling coarse materials and tertiary and quaternary crushers reducing ore particles to finer gradations. This paper focuses on review of a work carried out by researcher...

Many research studies have been conducted on the liberation of locked minerals using a crusher and comparing this device with the other devices. This paper reviews the liberation of middle coal by different methods of crushing force. In the Tabas coal washing plant, particles of 0.5-50 mm size are processed through the heavy media method (using 3 Tri-flo separators) and particles of 0-0.5 mm si...

The condition for the appearance of additional dynamic forces in presence gaps journal bearings jaw crusher is determined. design backlash eliminator equipped with pneumatics described. It was experimentally established that use pneumatic devices elimination interfaces moving links, using bearings, during operation crusher, reduce magnitude accelerations and, therefore, increase reliability as ...

A dynamic model of the working mechanism a compound pendulum jaw crusher with clearance is established by Lagrange multiplier method (LMD) based on L-N contact force and modified Coulomb friction model. The correctness verified MATLAB Adams comparison simulation, best selection range driving speed size determined according to laminating crushing theory (LCT). effects shock chaos phenomenon in a...
