How to eliminate failure of jaw crusher

Jaw Crusher troubleshooting methods:

1) removal of the blockage of discharge opening to ensure a smooth material;

2)tighten or replace the V-belt;

3) to re-install or replace the adapter sleeve;

4) adjusting the voltage is the workplace, to conform to the host operating voltage requirements;

5) the replacement of bearings.

Jaw Crusher Symptom:

Host slot round, moving jaw functioning normally, but broken cease work.

Reasons: 1) tension spring break; 2) rod fracture; 3) brackets off or broken.

Remedy: 1) the replacement of tension spring; 2) Replace the rod; 3) to re-install or replace the brackets.

Yield was less than the factory standard.

Reasons:

1) the hardness of the material to be broken or toughness than the limits prescribed instructions;

2) reversed the motor terminal location, the host to open anti-vehicle (moving jaw clockwise rotation), or the motor connected in delta connection star connection;

3) nesting population less than the specified limit;

4) jaw movement, tooth tip and tooth tip relative;

5) low voltage work site;

6) after the moving jaw and bearing wear gap is too large, the relative occurrence of the bearing outer ring rotation.

Remedy:

1) to replace or increase crusher;

2) swap the motor wiring;

3) nesting I adjusted to the nominal specification requirements and increase the discharge opening of the crusher for crushing;

4) Check the size of the tooth plate pitch, such as be sub-standard replacement jaw crusher plates, align the activities of the fixed jaw plate and the relative position of the jaw plates to ensure the tooth tip of the tooth root, the fixed clamp, to prevent displacement;

5) to increase the voltage of the workplace, to adapt the host re- load requirements;

6) the replacement of bearings or moving the jaw.
