It is impossible to outline the exact limitations for loading a shaker, as resulting
shaking action is dependent upon several factors. Principal among these is the size
and shape of the containers, speed, orbit radius, and the amount and type of
material being shaken.
Basic considerations should be:
•
Use lowest speed consistent with the required shaking action.
•
At higher speed use less weight on platform.
•
When using a tiered platform (one platform above the other), place equal load on
each or, if possible, place heavier mass on lower platform and lighter on the top.
If shaking action imparts a “whip” to the upper platform, then either the speed is
too high or the load is too heavy on that platform.
•
If shaker has tendency to “walk” on floor, then rubber feet should be secured to
the floor using rubber or contact cement.
Good judgment in the selection of the factors will contribute to proper use of the
shaker.
BELT INSPECTION:
Remove top plate and inspect belt annually and replace if actually broken or if
the cords are exposed and frayed. In the case of a high duty cycle inspect every 6
months. Small outer fabric breaks are not harmful.
BELT REPLACEMENT AND ADJUSTMENT:
To replace belt, loosen motor mount screws and drop belt below both pulleys.
Install new belt (Stock #4220) and tighten the motor screws but do not tighten belt to
the point where the bearings will be overloaded. When belt is tight, the operator
should be able to press lightly on the middle of the belt and cause it to bow in an
amount equal to the width of the belt.
