GENERAL DESCRIPTION
Upper hanger (suspension arm) brackets are pre-
assembled, at the factory, to a flanged cylindrical
section. It insures proper alignment of the
suspension arms and sleeve clamping surfaces.
Flanged mounting ring may be provided with bolt
holes for bolting to a mating flange on the bin.
Note: Nuts, bolts and gasketing for the mating
flanges are not supplied by Metalfab.
Use high strength, grade 5 bolts and
locknuts.
When being installed on a conical section of a bin, it
can also be welded directly to the bin cone. The
cone may be butted against the horizontal or inside
diameter of the flange and seal welded.
Before doing any welding, remove the vibrator from
the Bin Activator.
In all cases, regardless of installation procedures,
the mounting flange must not be distorted or bent
during installation.
Even though the locating of suspension brackets is
done with special equipment, it is recommended that
mating parts be maintained, i.e., do not interchange
mounting flanges from one serial numbered unit with
another serial numbered unit.
To insure proper fit and alignment, plan view
orientation of the hopper mounting flange with
relation to the Bin Activator must not be changed.
In most cases, generally 3 foot through 8 foot
diameter units, the mounting flange is shipped pre-
assembled to the Bin Activator. For 10 foot diameter
and larger, the mounting flange is split in half and
shipped on the same skid as the Bin Activator or
separately. A metal brace may be welded to each
half section to prevent distortion during shipment. If
so,
* remove * after * installation.
INSTALLATION – ASSEMBLY
Specific sequence of installing a Metalfab Bin
Activator can be changed to suite individual
requirements. Most important is the end result, i.e.,
proper alignment and tightness of nuts, bolts and
sleeve clamps.
Plan view orientation of the vibrator location with
respect to the storage bin is not critical. It can be
located to suit.
For units provided with bolt holes, the bolt holes can
be pre-drilled in the mating bin flange. Care must be
taken to make certain that the flange is not warped
or not distorted. If the bin flange is warped, distorted
or not level, transfer bolt holes from the mounting
flange at the time of installation. Shim, with metal,
as required before bolting mating flanges.
The mating flanges can also be welded, continuous
internal and intermittent or continuous external.
When bolting the mating flange, it is good practice to
user a sealant such as Permatex, Silastic or similar
material between the flanges to prevent leakage of
fine particle size products. A thin, approximately
1/8” gasket of resilient material may be used in place
of
* a * sealant. ** Sealant * by * others.
After installing the completely assembled Bin
Activator and tightening all bolts, run the unit empty
for approximately ten minutes. Then recheck the
suspension arm bolts, vibrating mounting bolts and
