The choice of amplitude is based on the particle size and nature of the material being screened In general, the larger the vibrating screen size, the larger the amplitude selected When the linear vibrating screen is used for classification, the amplitude is slightly larger; when used for dehydration and deliming, the amplitude should be smaller
Vibration motors are not used on their own – they’re attached to a product/device/piece of equipment that is intended to vibrate Therefore we are interested in the whole system (motor + target mass) We measure the vibration amplitude by mounting the motor on a known target mass and reading the results from an accelerometer, see more here .
Eriez High Deflection Screeners have the advantages of an electromagnetic design with the added benefit of high amplitude Operating at a fixed 1800 vibrations per minute and approximately 1875 amplitude, the HD designs offer the nearly maintenance-free operation of our electromagnetic design with high amplitude, similar to a mechanical screener
