Accu-Max Spinning Riffler: SP-245 & SP-245F
Page 3
The Accu-Max Spinning Riffler is designed for accurate
sampling of large quantities of free-flowing bulk materials
up to 2in (51mm) topsize. The hopper holds up to 1.8cft
(51L) of starting material which is sampled into eight
collection pans. Pans of 1/4 size, which are also available,
may be intermixed with the 1/8th pans.
The SP-245 is shipped mounted on a skid and enclosed
by a wooden crate. If there is visible damage to the crate
when you receive the machine, unpack it immediately, and
note any concealed damage on the freight bill.
Remove the wood screws which secure the crate to the
skid, and lift off the skid with a hoist or forklift.
Choose an operating location with a level floor and
adequate ventilation. Use a forklift to move the SP-245
to the operating site. Remove the lag bolts which secure
the machine to the skid. Pass lifting straps under the
framework at the top of the hopper, and use a hoist or
forklift to raise the machine off the skid and place it where
it will be used.
LEVEL the SP-245, and fasten it to the floor using anchor
bolts or other fasteners and the holes by which it was
mounted to its skid.
Install the hand crank on the gate stem and tighten with
a wrench.
Provide Electric Power for your Machine:
The SP-245 Spinning Riffler is normally wired for
110V/60Hz and is supplied with a power cord and plug.
The SP-245F model is wired for 230v/50Hz operation and
is supplied with a power cord. Connect only to a properly-
wired, grounded receptacle with appropriate electrical
current for the machine.
If your machine has a different voltage, have it installed
by a qualified electrician in compliance with local and
national wiring codes. A wiring diagram for your machine
is provided.
ALWAYS properly ground your machine.
NOTE: Read and understand ALL safety and
operating instructions before operating your Accu-
Max Spinning Riffler.
Observe the Control Panel:
The dial increases and decreases the vibration rate of
the feeder.
The toggle switch turns the vibration on and off.
The Start/Stop buttons turn the rotation of the turntable
on and off.
The highest sampling accuracy is normally achieved by
slow feeding (about three minutes to empty the hopper).
The turntable rotates at about 14rpm on an SP-245 (about
12rpm on an SP-245F), and Gilson recommends 35 or
more presentations to each pan. Experimentation with
various samples is the best way to optimize settings and
procedures. You can standardize the gate position for
multiple samples by clamping a split collar on the stem.
1. Install the pans on the turntable. Each pan has a lip
which overlaps the top of the pan to its left. Lock the
pans in place by sliding the sample pan retainer down
the drive shaft.
2. Use the hand crank to adjust the hopper gate so that
it is
NOT in contact with the feeder.
3. Push <START> to turn on the rotation.
4. Fill the hopper with your sample.
5. Set the dial to "1" and turn on the vibration at the
toggle switch.
6. When the hopper is empty, turn off the feeder and
turntable.
7. Raise the sample pan retainer, and remove the
individual pans for emptying. The sample pan retainer
should slide up and down easily on the shaft and
remain in position when released. If necessary, adjust
the tension in the spring-loaded allen-head screws in
the collar at the top of the sample pan retainer.
8. Replace the pans in their proper position as described
in Step 1.
