Vibrating screens are used to screen the material to Shaft calculations: Given data: Power transmitted by the shaft= 20hp Speed of the shaft =850 rpm Weight of the screen=4500kg Beam length =230cm Arm length =15cm Shear stress =650 kg/cm²
Two bearing circular vibrating screens with a screen box weight of 35 kN and speed of 1200 RPMmon. The centroid axis of the screen box and unbalanced load does not change during rotation. A four bearing vibrating screen F Class was developed to meet demands especially for iron ore, phosphate and limestone production industries.
Shaft calculations: Given data: Power transmitted by the shaft= 20hp Speed of the shaft =850 rpm Weight of the screen=4500kg Beam length =230cm Arm length =15cm Shear stress =650 kg/cm² Bending stress =1000 kg/cm² Case 1: Arm length= 15cm Twisting moment: Power p=2ПNT/4500 20=2П*850*T/4500
There are three regions that will lead to the sudden increase of vibration acceleration: 1 the load weight variates within 050 kg and excitation frequency variates within 4060 Hz 2 the
8/7/2015· Once the motor speed has been calculated, the G force can be calculated using this formula: G force = Stroke X w^2 / 1.8 X 10^6. where: Stroke = measured amplitude in mm. For optimal efficiency, a G force of 4.5 5.0 will supply sufficient acceleration to the feed to not clog or peg in the screening interface. 1 like.

25/3/2004· Dear All, Could anybody advise me as to how should I carry out calculations for a screening system.. What I mean is : A vibrating screen 2 bearing design has an eccentric shaft and 2 counter weights at the shaft ends. I would like to know what should be the amount of eccentricity on the shaft and how much should be the weights at the end
The vibration in the screen are generated by unbalanced weight of calculated design. The vibrating shaft is made of special alloy steel with streamlined stress design. The shaft is designed in such a way so that there is no stress concentration at any point.
W=The total weight of the vibration part of the body including the weight of the vibration motor When the vibrating screen cannot meet the requirements of the screening operation during operation, its
The dynamic response of the vibrating screen has a great impact on the screening efficiency and fatigue life of the structures. For the conventional dynamic design, the consideration of the
25/3/2004·ņ Vibrating screen is a vibrating system. Thus, screen deck mass plus material mass on deck is total mass which is resting on springs. This is vibrated by exciting force. Mass, spring stiffness, damping factor hysteresis losses and exciting forceplementary and together will create desired vibration.
22/12/2006· Yes, for the vibrating radius you can use the amplitude of the screen when fully laden provided that when determining mR you use the weight of the fully laden screen. Alternatively you can use the unladen amplitude multiplied by the unladen screen mass theoretically both will give the same answer.
A separate calculation is required for each deck of a multiple deck screen, Generally, about 5 to 7 GPM of water is used per STPH of solids fed to the screen. Applies for weights other than 100 lbs. per cubic foot.
