2022514 The optimum crushing action is achieved by reducing the gap between the hard crushing surface attached to the spindle and the concave fixed liners mounted on the mainframe of the crusher. The passage opening and closing are done by an eccentric drive provided at the bottom of the spindle which leads to gyration of central vertical spindle [ 7 ].
