g-force for optimal material stratification with a maintenance-friendly design. MAINTENANCE-FRIENDLY DECK FRAME The F-Class' deck frame is lock-bolted rather than welded. Lockbolts are proven to be more effective than welding in the demanding, load-bearing, high-vibration operation of a vibrating screen to ensure the machine's
Experience indicates that a g-force range of 3 - 7 is required to achieve good stratification, which is important for classification and dewatering. Enduron® screens typically operate at a g-force range of 4.5 - 5 thanks to our range of high g-force exciters and vibrating motors. A unique feature of the Enduron® vibrating screen is
screen under the force of gravity. When viewing a screen opening from above, the more horizontal the screen deck lays, the larger the opening appears. This difference in effective screen opening between flat and incline gives flat screens greater capacity for the same wire opening size. Figure 2 is a demonstration of the effect.

The force m¨x exerted by the mass on the spring is equal and opposite to the force kx applied by the spring on the mass: m¨x + kx = 0 (2.4) where x = 0 defines the equilibrium position of the mass. The solution of Eq. (2.4) is x = A sin k t + B cos k t (2.5) where the term k/m is the angular natural frequency defined by ω n = k rad/sec (2.6)
Oct 16, 2018· Importance of "Throw" and "G" Force "Throw" is the term used by vibrating screen designers denoting the distance that a vibrating screen travels during its operating motion. The term is also referred to as "stroke". For a straight line motion screen the "throw" is the distance between the extremities of motion.
