In the crushing process of jaw crusher, Jaw crusher plate often appears problem both in mobile jaw plate and fixed jaw plate,which directly effects jaw crusher crushing capacity and leads to jaw crusher low crushing ratio.Great Wall company on basis of 50 years experience and analysis on Jaw crusher plate design improvement.
To the question of Jaw crusher plate,Great Wall engineers thinks that is the reason of jaw crusher plate structural drawback.The following design improvement is made by Great Wall company using in the new type jaw crusher plate.
Firstly, the overall thickness is enlarged from 170 mm to 240 mm in jaw crusher plate,and then Great Wall company design the hollow slot in the jaw crusher plate back.So as to improve jaw crusher plate strength and prevent the crack appearing.On the second,To prevent loose in jaw crusher plate, Engineers design two clamp block in the back,which is corresponding to mobile jaw and fixed jaw.In order to prevent jaw crusher plate crack in screw hole edge as a result of strength decline, increase metal area around the screw holes, weight loss not open slot, polish screw hole edge by chamfering grinidng wheel to avoid stress concentration phenomenon.
