Failure modes ball mill gear failure reasons gear performance for the following situations: excessive wear, abrasive wear, pitting and tooth fracture and other forms. Gear failure causes are the following: 1) the working environment and working conditions since the lubrication, auxiliary drive gear ball relatively poor working conditions, a ball mill price, the dust particles in the air are more poor seal condition. Lubrication of artificial periodic lubrication, therefore prone to these problems Gears: oiling is not sufficient, condition poor secondary seal gear, metal surface susceptible to dry friction caused by excessive wear. 2) the degree of coincidence in the transmission gear pair of single tooth under load time should be significantly longer, which is an important cause of excessive gear wear. The coincidence of the backlash would inevitably lead to lower increases, so some impurities and floating in the air and dust easier access between the meshing face gear, causing abrasive wear occurs. 3) present on the tooth surface contact fatigue strength of the gear stress concentration, when the top of the gear teeth into engagement, in excessive exposure equivalent under shear stress, the surface layer of the original cracks. Gear operation, the contact pressure on the high pressure oil wave at high speed into the crack, the crack walls have a strong impact action fluid; at the same time, deputy surface of the gear may be cracks mouth closed, so that the oil pressure inside the crack further rise and forcing the crack propagation direction and the tooth surface to the depth direction, the material from the tooth surface loss, the formation of pitting. 4) After the tooth root bending fatigue strength of the gear running for some time, a ball mill working principle, the axis of the pinion axis and mill rollers may become parallel, then become a local contact gears, gear over the entire tooth width discontinuity, gear shaft prone to bending and torsional deformation, so that the load is distributed unevenly along the tooth width direction. Ball mill test what issues need attention after the installation is completed, the need for a full range of inspection, there is no problem after commissioning work can be carried out. Before starting commissioning, it must be prepared to work and inspection work and so on. So what issues need attention ball test it? Continuous operation 1. The mill empty load test run should be between 12 to 24 hours, if the operation should promptly solve problems found. 2. After air load Turning confirm eligibility, can be carried out air load (without the ball, do not feed) test. 3. The operation of the process to check the lubrication lubrication, to ensure no leakage. The mill main bearing temperature must not exceed 50 degrees, if the main bearing temperature is too high, we must take measures to cool. 5. To ensure that no significant changes in energy consumption, more than eight hours of continuous operation, no abnormal incidents. 1. load test load test before a ball mill to join the 20-30% of the specified amount of load of steel balls and materials, running 8-10 hours. After normal operation, the amount added in the ball milled for the job. 2. Load test, the feeding situation should typesetting material, Panjin ball mill, ball and cylinder liner to avoid unnecessary wear loss and damage. 3. To ensure the smooth working whole mill, a ball mill factory, there is no sharp vibration. If severe vibration should promptly review and eliminate the fault. 4. Check the friction parts, friction parts are not permitted burn-in phenomenon. 5. ball around seal must be kept in good condition, there can be water leakage, oil leakage.
