DYNAMIC BEHAVIOUR OF A VIBRATING JAW CRUSHER FOR DISINTEGRATION OF HARD MATERIALS

摘要

One of the trends in design solutions of crushers ensuring the crushing ratio of about 30 involves the application of the vibratory-impulse action to the material to be crushed. Crushers utilising these effects are referred to as vibratory crushers. During the vibratory crushing the material to be disintegrated is subjected to the action of last changing shearing forces, which leads to the material being crushed cither by applied impulses or by fatigue action, unlike conventional crushers where the structure of the material is damaged by the applied pressure. A dynamic analysis of the vibrating jaw crusher operation is provided and its potential application to crushing hard materials, such as alloy materials containing iron and slag from metallurgical processes are explored.
