Experimental determination of vibration jaw crusher perfomance and characteristic of the crusher two-motor drive in no-load and nominal mode of operation

Article preview

The paper is devoted to the experimental study of jaw crusher characteristics under condition that nonidentity of subsystems electro-mechanical parameters causes the distortion of the nominal mode of the jaw crusher operation. Experimental data obtained have confirmed basic statements of a self-synchronization theory. The initial phase shift of jaws oscillations is shown to result in a substantial decrease in the crusher productivity and a significant increase in the specific power consumption.

Control of energy quality parameters in networks with nonlinear load

Article preview

This paper estimates the quality parameters of electrical energy in the electrical network of the St. Petersburg State Mining Institute. Experimental studies and computer modeling allowed to establish the influence of non-sinusoidal currents of PC power units on the degree of voltage distortion and overestimation of neutral current.
