The so-called flying cone, in popular parlance, is that the cone has no normal swing number and swing stroke, and the rotation number per minute exceeds the specified number of revolutions. General cone rotation speed n=10-15r/min as the crusher no-load limit speed, when the cone rotation speed exceeds this specified value, it is flying cone. When the crusher has a flying cone failure, the oil of the spherical bearing will be thrown out, and the ore entering the crushing chamber will “fly”, and the crusher can not play the role of crushing ore. Í alvarlegum tilfellum mun það valda skemmdum á snældunni og öðrum hlutum, sem hefur áhrif á eðlilega notkun. Til að útrýma þessari bilun, ættum við fyrst að skilja orsök fljúgandi keilunnar, til að gera réttar viðhaldsráðstafanir. There are many reasons for the flying cone, and each reason contains a variety of influencing factors, which are more complex, so it is necessary to analyze each influencing factor, find out the main cause of the fault, and put forward preventive measures.

When the equipment is running, the spindle will collide with the lower part of the cone bushing, resulting in stress concentration, so that the lower end of the cone bushing wear speed increases, gluing occurs, and even rupture, resulting in flying cone. In order to ensure the normal operation of the cone, it is necessary to make two-thirds of the contact area of the entire bowl tile in the outer ring, one-third of the inner ring and the cone surface are not in contact, so that the spindle and the cone bushing are in contact with the upper part of the cone bushing height, and the wear of the contact surface is observed during the maintenance of the crusher. If the spherical bearing is not in contact with the moving cone sphere along its outer ring, but along its inner ring, and the conical spindle is in contact with the cone bushing at the lower part, it can be considered that the production of the flying cone is related to the abnormal contact between the spherical bearing and the moving cone sphere, and the main solutions are: ① Increase the groove area of the inner ring of the bowl tile, the width of the contact belt is (0.3R-0.5R)(R is the horizontal radius from the center line of the spherical bearing to the outer ball), and the groove depth h=6.5mm. ② The inner ring of the ball tile is scraped and processed, and the contact point is not less than 3-5 points on the 25mm*25mm area, and the wedge gap of the non-contact part is 0.3-0.5mm.

4, poor lubrication crusher in the operation process, the friction between the surfaces that contact each other and have relative motion requires the intervention of lubricating oil to form hydrodynamic lubrication. Fullnægjandi smurning á vélinni mun bæta núning milli hluta, draga úr sliti og tryggja eðlilega notkun vélarinnar. However, if the oil temperature, oil pressure and oil amount of the lubrication system are not enough, especially the crusher working environment is harsh, the dust is large, and the dustproof system, if it can not play its due role, will seriously pollute the lubricating oil and cannot form an oil film, so that the lubricating oil not only does not play a lubricating role, but will aggravate the wear of the contact surface and cause flying cone.

Through the above fault analysis and the adoption of corresponding measures, can effectively prevent and solve the conical broken fly cone failure, while strictly standardize the daily operation, maintenance and overhaul, strengthen equipment management and on-site maintenance, grasp the quality of each link , rétt notkun, varkár viðhald, forðast á áhrifaríkan hátt að flugkeilubilun komi upp eða jafnvel ekkert.
