Modal calculation results of vibrating screen
Table 1 show that the natural vibration modes include rigid motion and bending deflection. The first six vibration modes are rigid modal and modal frequency is lower which depends on the vibration...Current screen capacity calculations do not take into consideration enough of the factors affecting screen efficiency. The old formulas were designed to keep calculations short and manageable for manual calculation. The common use of computers in today’s world makes it possible to do more complex screen capacity calculations in much shorter time.SCREEN CAPACITY CALCULATION VIBFEM

High-frequency vibrating screens
High-frequency vibrating screens are the most important screening machines primarily utilised in the mineral processing industry. They are used to separate feeds containing solid and crushed ores down to less than 200 μm in size, and are applicable to both perfectly wetted and dried feed. The frequency of the screen is mainly controlled by an In order to reduce the excessive vibration responses of a reinforced concrete frame structure induced by several vibrating screens working simultaneously, field vibration monitoring and someVibration Test and Control of Factory a Building under Excitation
