The Study Of Application Of CAE Technique On The Ball Mill

Ball mill is one kind of universal machine widely used in metallurgy , cement, construction materials and chemical industries. Ball mill is characterized as large-scale, giant weight and complicated forces acting on it , and its most spare parts are strength ones. It was proved that damages of materials and process way .Because a ball mill should be carefully considered to avoid from deforming and splitting.In recent years, the first trend of mill development is not manufacturing large-scale machine, but focused on the depression of consuming of energy and steel as well as improving of mill working performance. The second trend is continuate innovating of structure, material, processing technique, working accuracy and product quality. Both equipment reliability and viability increasingly high,and equipment weight increasingly lightness.Hydraulic dynamical bearings and static force bearings are widely applied in large-scale equipment, which bring mill smoother start-up and transmission than other bearings do. Fueling injection fittings are used to lubricate gears, which prolong gears'working lives.Although the ball mill have very abroad application, the research about them is still rested on traditional method. As the development of computer technique and calculation procedure, the study on them is increasingly abundant and mature. While a ball mill is working, balls in the mill are lifted, and then are thrown away with a certain velocity to collide raw material. But at the same time, balls and underboarding are also got collision which may make balls and underboarding fracture.Considering the tough lubrication condition and dust and prills have easy access to meshing zone of gears, the heavy abrasion on gear surface often appears in the upstage gear of open-gear transmission of ball mill. The heavy abrasion...
