Study on Load Distribution in the Working Space of Lever Crusher

Paweł Ciężkowski , Jan Maciejewski


This paper presents laboratory jaw crusher stand equipped with special construction measuring system which allows to determine the load distribution in crusher’s working space. This system consists of nine independent segments, equipped with strain gauges to measure normal and tangential forces and moments. Additionally, crusher’s construction allows to measure forces acting on toggle plate and displacement of moving jaw, changes of rotary velocity and torque on machine driveshaft. In this research exemplary tests results of rock crushing processes realized on three sets of crushing plates were analyzed. Studies were carried out on flat, profiled plates with parallel teeth and plates with variable profile. Analysis of results shows significant differences in the quality of the process depending on the type of used plates. Plates with variable profile are favorable from load distribution and the crushing energy point of view.
