Troubleshooting crusher

According to Yifan Machinery Company 's long-term production broken machinery use and development of the crusher industry for common faults are summarized

   1 , crusher idling , the lower metal crash occurs . When jaw crusher work load , the lower metal crash occurs may be the cause of the following two aspects:

   ( 1 ) bracket bearing slide badly worn or loose bracket serious head wear should be replaced.

   ( 2 ) supporting the thrust plate or pad adjusting device crash occurs , generally due to elastic buffer spring rod disappeared or damage caused by strong rotation does not bear the weight of the spring , when the movable jaw plate , toggle plate , the body combination of the three not close, so that both ends of the support bracket head and produces shock, or adjust the mutual impact between the gasket should promptly tighten the compression nut until the crash disappears.

   2 , when working with metal percussion , linings jitter. This phenomenon is often crushing chamber side liner and tooth plate ( fixed, fixed ) loose, broken or loose screws loose or caused to be tightened or replaced promptly .

   3, after the brackets break frequently. In addition to transfer power after the brackets , but also by the lack of its strength from the insurance role . In addition to the strength of the middle bracket is too low , its strength is not sufficient to overcome the normal crushing ore crushing force resulting damage , the spring rod may be too tight , plus the crushing force at work overload and break it may be appropriate to loosen the spring .

   4 , the flywheel rotates the crusher does not work. The reason is because the rod spring and rod damage , making the trip rod nut emerge from the support bracket slider , toggle plate may be broken off , you should replace the installation.

   5 , a significant swing flywheel, slow rotation of the eccentric shaft . The failure is due to the pulley and flywheel key loose or damaged , the wheel can not be synchronized with the rotation of the shaft .

   6 , crushing and coarse grain products , is the result of the lower liner crushing severe wear . Replacement tooth or under the board should be replaced with new liner, adjust the port of discharge the required size .

  The above is a common crusher failure , if necessary, you can also log Yifan Machinery website for discussion.
