In recent years, many ball mills have adopted a liquid coupon, a liquid coupling application, and the liquid coupling is mounted between the motor and the reducer, and when the ball mill starts, the motor first drives the liquid coupher. The pump wheel starts, when a certain speed is reached, the output moment of the liquid coupling is equal to the load torque, the turbine begins to rotate, the ball mill is started, the benefits of the application of the liquid coupling are: First, provide the starting ability of the motor, improve acceleration Performance, the second is that the motor can be air-off, reducing the start current, and shortening the duration of the start current. Ball mill - new darling of mineralization equipment, innovation and production means of mineralization technology, and each user is convinced! The development of ball mills and technology is to save ball mill energy and steel consumption, develop new rate, low-energy ball mill, especially ultra-fine ball mill technology and equipment; improve the barrel liner material of the ball mill and structural profile Improve the morphology and material of the ball mill dielectric; and improve the ball mill transmission mode. Under the premise of ensuring the fineness of the ball mill, it is based on the efficiency of the spherical mill, reducing the energy consumption, steel consumption and product manufacturing cost of the ball mill. The installation methods and sequences of various types of ball mills are roughly the same, and must ensure the quality of the installation. It is necessary to strictly abide by the manipulation and maintenance procedures when manipulating, and do a good job before starting, start and parking should be strictly in accordance with the programs. Combine maintenance work and manipulation, maintenance can be divided into small repair, medium repair and overhaul in addition to daily maintenance inspection. For common stails of the ball mill, we must know the causes and rule of the fault and the subject matter.
