The standard inclined screen has an angle of inclination of 15 o. Lower angles of inclination increase the projected area of the screen aperture in the horizontal plane and the screen can handle a greater load. This is accounted for by capacity factor K6 K 6 1.0 0.01(. 15) (4-11) where . is the angle of inclination in degrees. The wet screen ...

Higher levels may also need to be allowed when higher-vibration sources are nearby. An example is a diesel engine driving a gearbox and a high-speed pump, all on the same common skid base. The gearbox and pump vibration may not meet their specified levels because of the thumping from the engine, but all three machines may be O.K. to operate as is.

screen sheaves are specially machined so that, when in operation, there is a point of zero sheave run out. In other words, if a line were drawn from the center of the driven sheave through the center of the motor sheave, there would be no movement towards or away from the motor sheave where that line crosses the outer diameter of the screen sheave.

2) Increase stability on the vibration isolators by limiting dynamic deflection. If a machine (such as a diesel engine, forging hammer or electro-dynamic shaker) generates relatively large forces during its operation, the overall movement of the machine on its isolation …

Above figure shows construction of an unbalance motor. To generate the centrifugal force, flyweights are arranged on both sides at the ends of the motor shaft. The unbalance weights on the drive shaft produce an oscillating force which sets the spring-mounted working device (e.g. a vibrating screen) to vibrate in a defined direction.

vibration testing It is generally demanded that a random Signal should contain peak-values of three times the RMS value. The force produced by an exciter is mainly limited by the heating effect of the current. i.e. the RMS value. whereas the power amplifier rating is influenced by the peak

vibrating frame and screening surface. Dual vibrating mechanisms are standard on 2 and 3 deck, 8' x 20'; and on 2 deck, 8' x 24' screens. Triple vibrating mechanisms are standard on 3 deck 8' x 24' and larger units. The two shafts of the dual mechanism are each individually motor driven while the triple mechanism is driven on the feed end
