Abstract |
In this work, we propose to study the dynamic behavior of a primary jaw crusher. It shows cracks and deformations in the structure and on the flywheel. This jaw primary crusher, capacity of 400 tons / hour, is modeled and studied numerically and experimentally. Using the Solid Works simulation software, one part of the system is treated: eccentric shaft assembly, connecting rod and moving jaw, as well as the drive pulley and the flywheel. Also, we studied the vibratory behavior of this installation practically, and this by a programming of the points of measurements of vibrations using a software of vibration analysis XPR 300. Then we took samples of vibration measurements using an Analyzer. The spectral interpretation reveals the presence of a shock on the eccentric shaft line, causing a play in the rolling bearings of the shaft. The comparison of the results of the numerical simulation obtained with those found experimentally makes it possible to conclude the appearance of a resonance of the structure by causing cracking and deformations.
