Optimal number of revolution the eccentric shaft of a jaw crusher with a simple motion of the moving jaw

Abstract

The paper analyzes forces acting on a piece of raw material in a jaw crusher with a simple motion of the moving jaw, and based on this defines the formula to define the optimal number of revolutions the eccentric shaft. Under the optimum number of revolution the eccentric shaft, the number of revolutions is assumed to ensure that the crusher achieves the maximum crushing capacity.

Optimal number of revolution the eccentric shaft of a jaw crusher with a simple motion of the moving jaw

“…Having in mind the geometry of the workspace of the jaw crushers with the free movement of the moving jaw, and the obviously resistance the frictional force to the moving and fixed jaw when the crus-hing product is discharged, the optimum speed of the crusher eccentric shaft can be determined according to the formula (25), defined in this paper.

“…Another approach (Magdalinović N, 1980/81) [2] is based on the assumption that the crushed products does not fall freely from the level of BB1 to the level at the discharge opening AA1, but during the discharge, the crushed product slides along the steep level B1A1 on the mobile jaw ( Fig.1). According to this assumption, the optimal number of rotations of the eccentric shaft is defined by the formula [2]:…”
