Impact crusher failure and the reasons for exclusion method defect characteristics

Impact crusher failure and the reasons for exclusion method defect characteristics

 1 product particle size is too large to tighten the belt too loose tighten bolts
 (2) the body swing to adjust to the particle size is too large particle size
 Remove the impeller channel clogging channel sealing material
 Block excessive wear caused by abrasion emphasis wear full body replacement
 3 sub-feeder metal crash collision with the impeller feeder mounting position adjusting
 1, regular observation of the door stands open observation of internal wear crushers, the center feeding tube, cone hat, impeller, the downstream channel lining, circular shield, wear block may wear, worn should be replaced or repaired, replaced wear should also replace the block, the block to ensure that wear the same weight. Crusher is strictly prohibited during work observed the door open observation of internal work to avoid danger. Found that the timely replacement of worn impeller body to find the manufacturer repair.
 Special attention, without the manufacturers consent is strictly prohibited without permission homemade impeller, or peril.
 2 car crusher Mobil grease grade, or 3 # Lithium Grease, working 400 hours per amount of grease to join, open 2000 hours to clean the bearing spindle assembly, generally work 7200 hours, replaced with new bearings.
 The upper bearing of the spindle assembly swimming side, the bottom bearing the fixed end, after the hand-pulled the pulley assembly should be flexible rotation.
 3, triangle belt tensioning drive size should be adjusted appropriately to ensure that the triangular tape by force, two-motor drive, the tape should be grouped on both sides of triangle matching, then the length of each group as uniform as possible. Should be adjusted so that the difference of not more than two motor current 15A.
 4, the operation of the crusher, because the device is a high-speed equipment, with special attention to safety. Personnel should stay away from the device, For the machine should be shut down after repair.
