Center Drive mill with large double row self-aligning roller bearings replace conventional babbitt-lubricated bearings, mechanical technology improvements through UOB bearing long life, good sealing, easy to disassemble and clean, and equipped with a manual timed dry petrol stations to refuel, lubricated bearings are in good condition, than the sliding bearing lubrication system is simple and reliable, since the bearing selection process for large bearings from the perspective of choice, which is much higher than the load carrying capacity of the mill at full load, and therefore, bearing Under normal conditions of life than the life of a ball mill, the device due to the use of cylindrical roller bearings, reducing friction and static resistance torque, coupled with the use of a fluid coupling and gear accelerator that is equipped with a motor power compared with conventional mill reduced by 10.7% - 40.5% Ex mill equipment, energy-saving effect is remarkable, only saving one, two or three years to recover the investment costs of the mill. Center Drive mill range of applications: Center Drive ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other production industries of all kinds of ores and other grind materials can be dry or wet grinding. www.zzyuxi.com Center Drive Mill Working Principle: This machine is a horizontal cylindrical rotating device intermittent mill equipment, outer gear, the two positions mill, the material from the feed device evenly into the mill into the compound empty-axis helical The first warehouse, the warehouse there are ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height After the fall, have severe impact on the material and abrasive material in the first After the warehouse to reach coarse grinding, the single-compartment plate into the second compartment, lined with flat lining inside the warehouse, there are ceramic ball mill equipment, the material to further grinding. Powder is discharged through the discharge grate plate to complete the grinding operation. Mill Center Drive Features: The machine consists of feeding part, discharging part, turning part and driving part (reducer, small transmission gear, motors, electrical control) and other major components, hollow shaft with steel, lined removable, rotary gear hobbing using castings, body inlaid cylinder liner wear mill equipment, has good abrasion resistance, center drive mill smooth operation, reliable work. Dynamic load ball directly when starting the analysis, when the ball start is divided into three phases: 1. In the case of the work unit is not moving, there is a gap due to the transmission system, the prime mover of the rotor acceleration. 2. The movement of the working device yet, due to the elastic deformation of the drive system, the prime mover of the rotor has been moved to the drive system until the force is equal to the external resistance. 3. The working device begins to move, during the period of the first and second stages, the prime mover of the rotor with a certain speed, drive to get early deformed, the deformation is applied to the resistance of the working device adapted. The dynamic load when starting is segmented ball mill drive train account for the presence of the gap, through the friction clutch segments start from the power curve, and the angular velocity of the elastic force of the clutch in starting torque increase, the transmission-based elastomer member moment, changes in the corresponding angular velocity. www.zzyuxi.com mill equipment is a typical large inertia overloaded equipment, design, manufacturing and field installation use, should fully consider the impact of vibration dynamic load. Clearance 1. ball mill drive system enables a greater impact on the dynamic load at the start, and the drive gear clearance gap primarily, if not high precision gear manufacturing, it will have a gap. 2. The impact of dynamic load is proportional to its stiffness, for the start of the mill segment, due to the greater flexibility of use of pneumatic clutch or hydraulic coupling, all help to reduce system stiffness. 3. Reduce the system stiffness can increase the durability and life of ball mill transmission equipment, because the elastic vibration natural extension of the periodic system, while the vibration frequency is reduced.
