HP300 cone crusher is a crushing equipment imported from France for the crushing workshop of artificial sandstone aggregate processing system for water conservancy and hydropower construction project. It has advanced structure design and large crushing capacity. It can realize the specific adjustment of medium and small stone demand according to actual engineering needs. Due to the lack of inspection or lack of responsibility in actual operation, some artificial equipment failures may occur, especially in the design of single-line process production process, which will seriously affect production and even paralyze the entire system. Because HP300 is one of the most important, most important and most expensive main equipment in the medium crushing workshop, it is necessary to analyze and study the possible causes of human equipment failure of HP300 cone crusher , reduce and eliminate accidents, and ensure HP300 cone crushing. The important content of the normal operation of the machine has important practical significance in the project. 2. Humanized failure of HP300 cone crusher (1) The bushing on the moving cone is seriously worn by the spherical tile, which causes the inner wall of the bushing on the moving cone (commonly known as the copper sleeve) to detach the copper scrap to block the spherical oil passage, so that the crusher generates strong vibration when it runs. (2) The fixed cone cannot be rotated out normally with the adjusting ring, which makes it impossible to replace the moving and fixed cone lining plates properly, so that the crusher cannot replace the wear parts in time. 3. Analysis of the causes of human failure in HP300 cone crusher (1) The inner wall of the bushing on the moving cone is worn. The moving cone is seated smoothly on the spherical tile supported by the spherical tile. The lower part and the weight fixed on the eccentric sleeve (the weight is covered by the auxiliary cover) are close to each other. Timely detection of the sub-cover wall is seriously worn, causing the crusher to directly impact the outer wall of the counterweight, and then the sub-cover and the counterweight fixing screw are loosened and detached, which directly causes the moving cone to not balance the operation, resulting in the taper sleeve on the moving cone being the outer surface of the spherical tile Severe wear and tear, causing strong vibrations in the crusher. (2) The fixed cone cannot be taken out normally with the adjustment ring. The outer diameter of the fixed cone is machined with a screw, which is supported by the heavy-duty thread in the adjusting ring to be supported in the adjusting ring, and the fixed cone in the adjusting ring is rotated counterclockwise or clockwise to realize up-and-down adjustment to achieve adjustment The size of the feed port and the discharge port, and for the regular replacement of the moving and fixed cone liner. In actual operation, since the operation time is too long normal wear lining large fixed cone, HP300 crusher fed on the iron belt conveyor can not be promptly sucked out large cast iron blocks (such as excavator teeth and the like) operator Did not find the manual detection in time, directly into the crusher, the crusher over-iron protection failure, can only be forced to be crushed by the crusher, so that the lining of the fixed lining of the iron parts is convex, causing the fixed cone can not be taken out. 4 Conclusion The man-made mechanical failure that may occur during the operation of the HP300 is a bottleneck that seriously affects the normal operation of the equipment during mechanical operation. Such machinery is an imported equipment. Once these faults occur artificially, under normal circumstances, there is no way and unconditional treatment at the construction site, and it can only be returned to the factory for repair, which is time consuming and costly to repair. Therefore, it is essential to strengthen the specialized training of the operational operators' mechanical business knowledge, especially the responsibility education, the introduction of strict equipment management system, and the implementation of effective measures such as special planes to avoid and eliminate these faults, thus ensuring the HP300 cone The normal operation of the crusher effectively reduces production costs. 500L Blow Molding Equipment,5000L Blow Molding Equipment,machine to produce 500L Weifang Yuyang plastic machinery co,.ltd, , https://www.yuyangmach.com
