The number of vibration motors commonly used in the vibration screening equipment industry is generally divided into three categories, namely, two-stage vibration motors, four stage vibration motors, and six stage vibration motors. The motor of vibrating screen can be divided into vertical vibrating motor and horizontal vibrating motor, both of which have 2/4/6 grades.
Generally speaking, the single flange structure of vertical vibration motor makes it easy to install and maintain, simplifies the host structure, reduces the cost of the host, and makes the host handle more materials, which is mainly used in rotary vibration screen models.
As a special asynchronous motor integrating two sources of vibration, the horizontal vibration motor has a wide range of applications. It is a new, energy-saving and universal vibration source for various vibration equipment, and has been used in linear shale shaker, mining shale shaker, vibration platform and other equipment.
During the operation of the shale shaker, the motor will drive the exciter in the shale shaker, and the exciting force will force the screen body to drive the screen. The speed of the exciter can be set according to the operating conditions of the shale shaker, and the speed of the shale shaker can be adjusted.
The general reason for the vibration disorder during the operation of the shale shaker is that the motor output is uneven, so the motor can be adjusted. Later, the shaft is worn. If the bearing can be repaired, it can be repaired in a timely manner. If it cannot be repaired, the shaft can be replaced.
At present, the high speed of shale shaker equipment is 3000 revolutions, which is generally high-frequency shale shaker equipment. The shale shaker uses the vibrating motor as the excitation source. According to the different forms of shale shaker, the number of motor stages used is also different.
The circular vibrating screen (S49-600-2000) uses a single vertical vibrating motor as the excitation source, and uses a four stage motor with 1450 rpm;
The rectangular vibrating screen uses two horizontal vibrating motors as the excitation source, and uses a six level motor with 960 rpm;
