The working principle of the vibrating screen is that the motor drives the V-belt to generate centrifugal inertial force, and the parabolic motion of the material on the screen surface is caused by the amplitude of the vibrator and the vibration of the screen box. The vibration frequency and amplitude of different types of vibrating screens are different, mainly depending on the vibration control strength of the vibrating screen. In the final analysis, the model and power of the motor are different. Today we invited an expert from a vibrating screen manufacturer to tell us how to control the amplitude of the vibrating screen through the choice of the motor.
Author: Hello, thank you for taking the time to accept our interview. Can you talk to us about the role of the motor in the vibrating screen structure?
Expert: The appearance of the vibration motor actually simplifies the structure of the vibrating screen. Why do you say that? Our R&D center has done data analysis when studying vibrating sieve samples. In order to ensure effective material screening, the vibrating machine must have a stable excitation source. The calculation of the number of vibrations and the magnitude of the exciting force is omitted, and the transmission capacity can be calculated by the motor power, which greatly saves the development time of our equipment.
Author: Is the motor power a decisive factor in the vibration frequency of the vibrating screen?
Expert: Accurately speaking, the main factors affecting the vibrating screen vibration control parameters include motor type and motor power. In addition to affecting the vibrating screen screening frequency and the number of vibrations per unit time, these two key parameters will also play a role in the power consumption of the equipment. Motors with 4-15, 4-18, 4-22, 4-30, and 4-37kW power consumption are also different in hourly power. It is recommended that you plan according to your own investment cost.
Author: What are the special requirements for the vibrating screen control circuit?
Expert: This is not a special explanation, as long as the current and voltage generated by the circuit equipment on site can meet the power of different types of vibrating screen motors. Be careful not to have a short circuit, or the voltage is unstable, which will affect the vibration frequency and amplitude of the vibrating screen, which is unfavorable for the screening process of the material.
