  • Checking the amplitude of a vibrating screen Fruitful

    The amplitude of vibration does not depend on the rotation of the vibrating mechanisms. Amplitude combined with rotation imparts a certain amount of acceleration to the equipment and that acceleration is responsible for the conveyance of the material. The larger the material to be conveyed, the greater the vibration amplitude of the equipment
