The main body frame is fabricated from MS. Heavy plates and reinforced by heavy horizontal and vertical ribs. Main bearing housing of both sides is machined in one operation for the longevity of the bearings. Moving jaw is fabricated from MS plates with box type structure it is machined and taper roller bearing is fitted with the eccentric shaft Jaw plates fix and moving both jaw plates are made of Manganese Steel casting. The fix jaw plate is retained by machined wedge plate to facilitate easy fitting and removal, Fly wheel - two heavy cast iron fly wheel are fitted on eccentric shaft and are balanced to ensure smooth running Shaft & bearing heavy duty, self-aligning spherical roller and taper roller bearings are used in the main frame and moving jaw assembly respectively. The Heavy eccentric shaft is made of EN-8 steel to withstand the stress and strain of crushing
