中心传动球磨机

　　中心传动球磨机是由电动机、液力偶合器、减速器、主轴承、筒体、进出料端部等组成。其所有部件位于同一轴线或同一平行轴线上。它以中心传动取代常规磨机的大小齿轮周边传动。
　　当电机空载起动时,液力偶合器中与电动机联接的泵轮从电机获得能量传递给工作油，当电机达到一定转速时，工作油高速冲击与负载联接的涡轮，从而驱动负载；当工作油降低能量后，又回到泵轮待重新吸收能量，这样往复循环，实现泵轮（主动）与涡轮（从动）之间的能量传递。因泵轮与涡轮之间只通过工作油实现上述柔性联系，所以能隔离扭振和冲击，使负载起动平稳。
　　中心传动球磨机由于采用圆柱滚子轴承，减少了摩擦阻力和静阻力矩，加上使用了液力偶合器和齿轮减速器，使配用电动机功率较常规磨机减少了10.7%--30%,节能效果显著。
　　Center drive ball mill is made up of electric motor, fluid coupling, reducer, the main bearings, cylinder, feeding and catching end. All of its components are in the same axis or parallel. It use center driving replace the conventional gear and pinion driving around.
　　When the motor starting with no-load, the pump impeller in the fluid coupling connected with motor ,then transfer energy from motor to the operation oil, when the motor reaches a certain speed, the operation oil attack the turbine which connected with the load at high-speed ,in this way, the motor drives the load; when operation oil reduced energy ,which returned to pump impeller and re-absorption of energy, so in this cycle back and forth, to achieve transferring energy between the pump impeller (the initiative) and turbine (driven). Because only the operation oil can achieve the above-mentioned flexible connection, so they are able to isolate torsional vibration and shock, and making the load start smoothly.
　　As a result of center drive ball mill using roller bearings which reduced the frictional resistance and static resistance torque, and coupled with the use of the fluid coupling and gear reducer ,in this way , compared with conventional mill ,center drive ball mill is able to make the electrical power decreased by 10.7% - 30% . Energy-saving effect is very obvious.
