VIBRATING TABLES FOR PACKING MATERIALS
Dense materials respond best to high-frequency vibration (3600 rpms or more), while light, fluffy or
flaky materials respond best to low-frequency vibration (1800 rpms or less). For packing or settling
materials use a vibrator with an impact force of 1-1/2 to 2 times larger than the weight of the material
plus container.
VIBRATING SCREENS
For self-cleaning screens, use a vibrator with a centrifugal force 4 times the weight of the material plus
the weight of the screen.
CONSOLIDATING CONCRETE
For 3-inch "slump" concrete, use a vibrator with the same force as the weight of the concrete and form.
For 1 to 2 inch “slump” concrete, an additional 30 to 50 percent force is needed. For dry mixes, (0
slump), add an additional 100 to 200 percent force.
CHUTES
The
force required of the vibrator is equal to the weight of the chute plus the vibrator plus the
maximum material in the chute. See page 11 for more details.

INSTALLATION CHECKLIST
CAUTION: The warranty is void if vibrators are not properly installed.
During installation, follow and check off the following steps.
1. Determine where the vibrator(s) should be placed on the bin, one-quarter or one-third up the
sloping side. Refer to Figure 1, page 6.
2. Select the thickness and size of the vibrator mounting plate and drill holes for mounting. Refer
to Table 1, page 7.
3. Determine the length of the channel iron. Refer to Table 2, page 7.
4. Weld the mounting plate to the center of the channel iron. Refer to Figure 2, page 8.
5. Weld the channel iron to the bin. Refer to Figure 2, page 8.
6. Install and secure the vibrator firmly on the mounting plate. Check the mounting plate for
warping. Shimming may be required to provide a flat surface for bolting the vibrator.
7. Plumb the vibrator. Refer to page 12.
8. On larger models, where a lug is provided, install a safety cable.
9. Make sure the vibrator produces sufficient force for the application. Refer to pages 14, 16, and
18.
