Working Principles Hydraulic pressure ball machine is powered by the electromagnetic motor speed control, through the belt pulley, cylindrical gear reducer, to the drive shaft by pin coupling. The driving shaft and the driven shaft be ensured synchronous operation through a gear .there is a hydraulic device behind the Passive bearing seat. Screw feeding driven by electromagnetic motor speed control. Put the material into feeding port with the belt wheel and the worm reducer. Cause the constant of the electromagnetic motor seed control until the weight of the screw feeder is equal to the needed weight, then the constant feeder pressure make the ball with stable quality. but If the feeding quantity is too high will lead to the electrical of the feeder machine overload. And also, it¡¯s not enough to make a ball if the feeding quantity is too small. So Proficiency in operation skills is an important condition to guarantee the normal work of the pressure ball machine.
