Reasons that Jaw crusher’s capacity can not reach factory standard

2016-12-27 14:03:39

Reasons:

1) Hardness or toughness of the material is over the limits prescribed by the manual;

2) Motor wiring position reversed, moving jaw has clockwise rotation

3) The discharge opening is less than the specified limit;

4) Jaws plates shifts, tooth tip is against the tooth tip

5) Low voltage in work site;

6) After moving jaw and bearing wear, the gap is too large, which makes bearing outer ring have the relative rotation

Remedy:

1) Replace or increase crusher;

2) Change motor wiring;

3) Adjust the discharge opening to the nominal one that manual stated or add a crusher for fine crushing

4) Check jaw plate and pitch dimensions, if sub-standard, jaw plate must be replaced; adjust the relative position of the fixed jaw plate and movable jaw plate to make sure the addendum is against tooth root, fix and press hard to prevent displacement;

5) Increase the voltage to meet host heavy load

6) Replace the bearings or moving jaw
