The typical failure and elimination of jaw crusher

Jaw crusher of typical faults and eliminate 2021 - 03 - 02 Wang Zhanguang, jaw crusher fault type and reason of 1. Bearing damage of fever, Jane pendulum jaw crusher are four sets of bearings, two to use as a support for eccentric shaft, two to moving jaw support, hanging on the eccentric shaft. Support bearing because of the bad environment, vibration is larger, oil pollution, easy to cause cage, roller wear faster, and ultimately broken, bearing damage more: there are lock set loose, bearing and shaft slipping of fever, the damage of bearing. 2. Jaw fracture and shaft fractured jaw and shaft fracture in addition to the material, and equipment vibration ( Such as bearing damage) And the crushing cavity compaction relationship is bigger. When the damage of bearing damage, or other parts, is bound to cause adverse phenomenon such as deflection of moving jaw, make additional load increase, shaft and moving jaw fracture. When discharging mouth is small, has broken material not discharge in time, crushing cavity is converged on material compaction, at this time due to the material elastic squeezed, jaw plate and shaft work, increased load, fracture all too clear. 3. The vibration of the vibration of the jaw crusher jaw crusher in addition to the work characteristics of itself, mainly bearing damage, loose fasteners, flywheel and pulley eccentric block produced change, or both have asymmetry, out of sync. 4, bracket broken bracket is the safety of the jaw crusher parts, when crusher load exceed the permitted range, first break, to protect the other important components. The reason for this is overload, such as compaction, foreign bodies, enter, raw material quality, etc. Second, the typical fault of jaw crusher to rule out 1. Bearing damage processing when bearing heating or other such as vibration found abnormal, should stop as soon as possible, check the reasons, such as oil, loose bearing inspection, the inspection. If discover bearing damaged, should be replaced in a timely manner, the selection of the bearing, clearance, because of large jaw crusher vibration, the heavy load. 2. Machine cavity of compaction compaction may come from the processor cavity into the material, material quality, discharging mouth too much adjustment is too small, you must stop feeding and cleaning cavity aggregate, adjust the feed opening size, avoid damage to the parts, if discover the bracket or moving jaw or shaft has been broken, need to do change, and formulate measures to fight this kind of accident. 3. Surge vibration processing that the crusher, may come from the bearing damage, loose flywheel counter weight dislocation, fasteners, etc. When dealing with bearing diagnosis, check the anchor bolt is loose, check whether the flywheel counter weight is misplaced, and recovery processing. 4. Other other aspects such as the influence of foreign objects will often happen, such as iron, hard material into the machine cavity, this needs from time to time to check, once a foreign body found yard should keep clear of in time, prevent accidents. Conclusion: this article only on several typical to the simple analysis of the cause of the accident is not comprehensive, nor depth, can only play the role of the topic, and tell readers due to the limited level of the author, in this paper, we have not decided, please comment.
