PROCESS DUTY EFFECT ON THE VIBRATION GYRATORY-CONE CRUSHER DYNAMICS

Abstract

This paper studies the effect of milled material on the dynamics and stability of the vibration gyratory-cone crusher where the body and milling cone oscillations are excited by two unbalance vibration exciters installed on the machine body. The laws of induced oscillations of the active crushing members with account for the motion viscous resistance as well as the equation of the power balance in the machine operating mode and the equation for determining the specific coefficient of equivalent viscous resistance, n, were deduced. The condition of synchronous existence of in-phase vibration exciter rotation mode and steady operation of the crusher was formulated, which imposes certain constraints on the maximum power of the motors in the machine operating mode used for material crushing.
