Spin Loader

General Description

The Spin Loader lets you utilize bulk storage facilities to their fullest
capacity. It eliminates the pyramiding which occurs when powders,
flakes and granular materials are loaded into bins, hopper cars and
piles and enables you to load up to 15% more product into virtually
any storage facility.

Compact, ruggedly-built, the Spin Loader consists of an inlet tube,
which guides the material through the unit and a spinner, which
distributes the material in a 360° arc or as refined by deflectors and
reduces the possibility of particle segregation and enables the particles
to intermix. The spinner is rotated by the use of a direct coupled
motor. Since the unit is completely enclosed, it totally eliminates
product waste, contamination and dust problems. The SL-100 is
supplied with a 2 horsepower drive and is rated at a maximum feed
rate of 100,000 pounds per hour. The SL-200 is supplied with a 5
horsepower drive and is rated at a maximum feed rate of 200,000
pounds per hour. For models other than these listed, check formal
quotation for horsepower ratings and maximum rates.

Installation

Except for the paddle of the optional rotary level indicator, the Spin
Loader is shipped assembled and ready for installation. After the unit
is unpacked, examine it for any possible shipping damage. Notify
carrier if any is found.

The paddle of the rotary level indicator is simply screwed into the shaft
end. A roll pin is inserted through the shaft to lock the paddle in
place.

The Spin Loader must be rotated at least once a month to insure
proper bearing grease distribution. If a high temperature or moist
environment is expected, the unit must be rotated at shorter intervals.
Please contact the factory for their recommendations.

Examine the nameplate data of the motor to see that it agrees with
the power circuit to which it is to be connected. Connect the power
leads or air line to obtain the specified direction of rotation. CORRECT

DIRECTION OR ROTATION IS STAMPED ONTO HOUSING***DO
NOT OPERATE IN REVERSE DIRECTION. The spinner should rotate

freely when turned by hand. The electric motor should run smoothly
with little noise. If the motor should fail to start and produces a
decided hum, shut down immediately and investigate for trouble.

Electrical and Air Requirements

The standard units are provided with either AC motors or air operated
motors. The electric AC motors are TEFC 900 RPM and operate at
230/460 volt, 3 phase, 60 hertz. The air motors are 4-vane models
and are provided with air mufflers. Both the 2 and 5 horsepower
motors operate at 900 RPM with 100 PSI air. The air consumption of
the 2 horsepower model will be 80 CFM (free air) with the 5
horsepower model requiring 150 CFM (free air).

Operation

The Spin Loader is designed to be hoisted by a lifting device. A power
winch with steel cable, spreader bar and safety hooks of sufficient
capacity (1/2 ton is recommended) is used to raise and lower the unit
as needed onto the hatchway or the hopper car. BEFORE THE SPIN

LOADER IS OPERATED, IT MUST BE SECURED TO THE
HATCHWAY OF THE HOPPER CAR, TRUCK OR BIN BY MEANS OF
SWING BOLTS, T-BOLTS OR CLAMPS. Start motor BEFORE

material is fed into the Spin Loader. Stop motor when hopper car is
fully loaded.

WARNING: The Spin Loader is not to be used as a lifting

platform for personnel. Use safe practices at
all times whenever raising or lowering.

Maintenance

Warning: The electric motor should be electrically locked-out
before any work is performed. Air supply for air motors must
be disconnected.
