PART 4 MAINTENANCE
OPERATING & MAINTENANCE ISSUES
Overfeeding Pulper
Feeding material too fast into the pulper will cause
machine vibration and low recirculation water flow.
Temporarily cease feeding material to the pulper
and allow it to process the current material in the
pulping chamber. Often, the pulping motor will
overload and shut down. In this case, manual
cleaning of the pulper chamber is required. Shut-
down and lock out main power to the unit, drain
pulping chamber and remove debris. If the pulper
motor does not overload, allow it to process mate-
rial until the vibration stops and the recirculation
flow rate returns to normal.
Level Probe
The level probe is critical to operation of the pulper.
If debris or fouling material is present on the level
probe, the probe will read a false high signal and
think that there is enough water in the unit when in
fact it is empty. The level probe, locate at the bot-
tom of the extractor, will show a red LED light
which indicates that it sees water. When this is lit
with no water in the extractor, it is an indication of
debris on the probe. The motors will start, but no
recirculation water will flow. Typically the motors
will overload and shutdown requiring resetting in
the main control box. Make sure operators of the
unit clean the probe daily.
Foaming
If a high rate of paper and cardboard are run
through the pulper, excessive foam may be gener-
ated. These materials have glue and adhesive that
cause foaming in both the pulper and extractor
chambers. Large quantities of foam will interfere
with the pulping and recirculation water flows.
Either use a defoamer or add paper and cardboard
at a lower rate to the pulping infeed.
Non Pulpable Items
While the pulper was designed to handle a large
variety of material, certain items will jam the cutting
blades and possible cause damage to the unit.
Iron, glass, silverware, stones, metal, bolts, un-
cooked beef and pork bones, ceramic, cloth, and
wood SHOULD NOT be fed into the pulper.
Drain
A clear and flowing drain is essential to proper op-
eration of the unit. A clogged drain will cause water
to overflow out the extractor door.
HIGHLY WET PULP DISCHARGE.
If the screen is clogged, the pulp will not properly
dewater. Check to see if the screen holes are
clean and clear. If the auger brush is worn, it will
not keep clear the inside surface of the extractor
screen. Proper brush fit so that it scrubs the inside
surface of the screen is required for dewatering
pulp and scouring the inside screen surface of foul-
ing material. These brushes require periodic re-
placement. It is difficult to determine when the
brush requires replacement as it is affected by run
time, feed material and feed flow volume. Mainte-
nance should periodically check the extractor and
auger for proper operation.
Worn Cutters
The rotating and stationary cutting blades are re-
placement items. If the pulp is not longer cutting
properly and the piping system is clogging due to
large pieces, an inspection of the cutting blades is
required. Worn blades must be replaced.
Corrosion
Although made of 304 stainless steel, the pulper
will be attacked by waste that is acidic or alkaline.
If your waster is corrosive in this manner, a buffer-
ing agent is required to neutralize the water before
it reaches the pulper.
