The vibration motor is the excitation source that combines the power source and the vibration source. It is the power source of the vibration screen. The vibration motor is selected correctly, so that the vibration machine can exert the best effect. Different types of vibration equipment used in different screening equipment, how to choose the right vibration motor model for the vibrating screen equipment?
Vibration motors are mainly divided into YZU, YZUL, YZO, JZO and other series.
| Model | Exciting force | Speed | Power | Current | Voltage |
| (KN) | (Rpm) | (Kw) | (A) | (V) | |
| YZU type | 1-75 | 3000 | 0.12-3.7 | 0.45-25 | 380 |
| YZUL type | 3-50 | 1500 | 0.18-2.2 | 0.6-5.1 | |
| YZO type | 1.5-75 | 1000-3000 | 0.15-5.5 | 0.35-11 | |
| ZDS type | 0.65-80 | 1450-2960 | 0.05-3.7 | 0.2-8.7 | |
| ZDJ type | 5-100 | 960-1420 | 0.5-15 | 1.5-34.8 | |
| VB type | 3-180 | 986-2600 | 0.2-13 | 0.55-27.8 |
| Level | Level 2 | Level 4 | Level 6 | Level 8 |
| Vibration frequency (r/mm) | 3000 | 1500 | 1000 | 750 |
| Amplitude (mm) | 2-4 | 4-8 | 8-12 | 12-16 |
Different types of vibration motors have different excitation forces and powers, so the range of use is also different.
According to the use occasion, it can be divided into ordinary vibration motor and explosion-proof vibration motor.
Explosion-proof vibration motor is equipped with an explosion-proof system in the ordinary vibration vibration motor. According to the characteristics of the screening material, it is judged whether the explosion-proof motor is used (whether the screening material contains flammable or explosive substances), and it can also be based on the screening material. The site has flammable and explosive gases or solid and liquid substances (where special attention should be paid to the dusty working environment, which is also an explosive site), and explosion-proof motors that meet the explosion-proof rating must be used.
According to the installation structure, it can be divided into horizontal vibration motor and vertical vibration motor.
1. Vertical vibration motor
Generally, it is a YZUL vibration motor. The single flange structure makes the motor easy to install and maintain, reduces the weight of the main engine and reduces the cost of the main engine. Various job requirements. It can be used in screening equipment such as rotary vibrating screen, ultrasonic vibrating screen and filter screen.
2. Horizontal vibration motor
The most common type is yzu, but there are also yzs, yzo and other models. The exciting force can be adjusted steplessly. It is easy to use and has a fully enclosed structure. It can work under any dust conditions without explosion-proof requirements. The vibration frequency and amplitude can be selected according to different purposes . Generally used in vibrating machinery of linear vibrating screen, straight row screen and vibrating platform.
| Series | Level 2 | Level 4 | Level 6 | Level 8 |
| Rotating speed | 2870 rpm | 1469 rpm | 960 rpm | 750 rpm |
Different types of vibrating screens have different vibration motor options. First determine the required motor vibration times and double amplitude. The number of stages of the vibration motor is divided into Level 2, 4, 6, and 8.
Since the application of the Level 8 vibration motor is very small, the manufacturer only produces it unless the user specifies it.
The Level 2 vibration motor has a relatively high speed and can reach 2870 rpm. Because of its high speed and low amplitude, it is also called “high frequency vibration motor”. The equipment used is: high frequency vibrating screen, vibration platform, etc.
The Level 4 vibration motospeed is not as high as the Level 2 vibration motor, which is 1469 rpm, but the amplitude is relatively high, which belongs to the medium-frequency motor series. The equipment used is: light linear vibrating screen, vibrating screen, etc.
The Level 6 vibration motor rotates at 960 rpm, which is suitable for screening equipment. The equipment used is: multi-layer linear vibrating screen, circular vibrating screen, etc.
The type, number of layers and output of the vibrating screen will affect the number of vibration motors.
One vibration motor is used for the circular vibrating screen and the vibro sifter.
Two vibrating motors are used for the linear vibrating screen .
The vibration platform can be used at the same time as 1, 2, 4, 6, 8 and multiple units.
The power of the vibrating motor equipped with all the vibrating screen products of Xinxiang Dahan is determined by rigorous technical theory calculation and repeated test. The motor power after shaping is the best performance of the vibrating screen, including the screening effect and service life. Please feel free to contact us any time.
