1) or tight set of external bolt;

 2) align the nesting population to ensure that the correct two jaw plate gap.
Plate elbow fracture.
1) Host overload or greater than the size of the feed material into the mouth;
2) non-broken into the crushing chamber of

 3) elbow plate and elbow pads between parallel plates, skewed

4) Casting a more serious casting defects.
1) replacement of the toggle plate and feed particle size control, and to prevent the host overload;

2) replacement of the toggle plate and take measures to prevent the entry of non-fragmentation broken cavity;

3) the replacement of boards and elbow replacement plate has worn elbow pads, correct Installation elbow plate;

4) qualified elbow replacement board.
Spring fracture.
For small nesting population, not relax spring.
Replacement spring.
Block off adjustment.
1) elbow plate, plate elbow pad their own procurement or restructuring, mainframe manufacturers do not meet design requirements;

2) at fixed adjustment bolts loosening

3) Block, a serious adjustment casting defects or welding defects.
1) Block replace and adjust assembly console manufacturers and the replacement of original toggle plate, plate elbow pads,

2) replacement of adjustment blocks and blocks bear the adjustment bolts;

3) replacement of adjustment blocks.
Bending or eccentric shaft fracture.
1) In the process of loading a host Rollover, the unilateralism of the eccentric shaft bending,

2) more than the hardness of the broken product brochures;

3) ultra-long-term negative mainframe operations;

4) elbow board sub-standard, non-detritus broken into the cavity from the fault protection;
5) eccentric shaft improper heat treatment, stress concentration, causing short-term fracture.
1) replacement of the eccentric shaft, the right lifting host;

2) replacement of the eccentric shaft, broken by the compressive strength of materials, select suitable breakers;

3) replacement of the eccentric shaft in tune with the work load or replace broken line;

4) replacement of the eccentric shaft, not to use inconsistent with the design standards elbow plate, plate elbow pads;

 5) replacement of the eccentric shaft, the use of heat treatment of qualified eccentric shaft.
Fixed jaw fracture.
1) left-intensive casting porosity, and other serious defects;

 2) the use of substandard elbow plate, plate elbow pads, crusher in strong shocks, the board has not since elbow protection;

3) moving the jaw displacement occurred in the rack , at the bottom end collision rack side boards;

 4) drawbars spring tension timely replacement has not yet expired;

 5) provides nesting population is less than the limit;

6) feed position is wrong, or the end of a biased angle too steep hopper, Fixed materials directly impact the jaw head.

1) replacement of fixed jaw.

2) replacement of fixed jaw. At the same time replaced the original console manufacturers elbow plate, plate elbow pads;

3) the replacement of fixed jaw. At the same time the correct assembly eccentric shaft, bearings, bushings and dynamic set tight jaw, and the replacement of damaged parts, and 4) replace the fixed jaw. At the same time replace the drawbars spring;

5) replacement of fixed jaw. At the same time, as required adjustment nesting population;
6) the replacement of fixed jaw. At the same time by doing-hopper to ensure that the material uniform, smooth, and the middle - to-2.
Rack housings or excessive temperature rise within the fixed jaw.
1) Bearing broken into too much oil or oil;

 2) hole plug, oil and not enter

3)-tank round with weights position deviation, rack beating;
4) tight in the axial movement of the hub;

4) to set up tight sleeve.
Rack cracking.
1) Casting defects or welding quality defects;

 2) the use of substandard elbow plate, plate elbow pads, crusher in strong shocks, since elbow board has not broken protection, a rack shattered;

3) of the fixed plate fixed jaw , a long-term ran from top to bottom, hit the wall rack before take-teeth-

4) at the end mainframe foot rigid foundation difference in the level of super-poor or collapse, rack beating;

5) rack stamp bearing two bolts loosening;
6) fixed in the activities of the jaw plates continue to be used after the tooth wear;

7) of the eccentric shaft, and marketing damage or expansion sleeve loose, groove to fly round the wrong direction with weights.
