5.1 WEIGHT ADJUSTMENTS

The vibratory motion of unit is controlled by addition or subtraction of weights
to balance cage pins. The top and bottom balance cages are round plates
(much like flywheels) with pins.
Top balance cage is known as horizontal cage. Weights added to this produce
horizontal or flat effect of screen. Thus, if you are screening heavy material,
more weights would be added to top cage to create inertia necessary to pro-
cess Sponge Media material. Good screening performance cannot be realized
until sufficient horizontal motion is attained first.
Bottom balance cage is known as vertical cage. Weights added to this cage
impose a vertical lift on screen which, in combination with horizontal motion,
moves material in a fashion suitable for good particle separation and dis-
charge.
Although weights on this unit have been preset at the factory, this is often just
a starting point -site fine tuning may be necessary.
Following are four weight arrangements and patterns they are most likely to
produce. These diagrams are general aids and should not be depended on as
precise adjustments for your application.
Adding excessive weight does not promote faster or better screening. Too
many poorly adjusted weights will only shorten unit's life. Acceptable screen-
ing is never accomplished by brute force, but by proper adjustment to unit.
Caution:
1. Before starting weight adjustment be sure to Lockout/Tagout the machine
each time there is adjustments that need to be made.
2. Feed limited amounts of material to the screen to check the flow pattern
and pinpoint what pattern is being illustrated in figures 16 through 19.
