Somat SPC-75S, Operation & Service Manual

Page: 31 / 66

SPECIAL OPERATING CONDITIONS - While applications vary widely the following
conditions could occur and should be watched for:
A. Overfeeding - The SOMAT

Pulper is designed as a continuous process
machine. In general, the feed rate should not exceed one tenth of the rated
hourly capacity in any six minute period. Exceeding this will cause the
machine to bog down and operate under its rated capacity.
B. Foaming - this is caused by contaminants in the water, or by certain
materials in the waste, such as glue in corrugated cardboard and excessive
starches. Add a de-foamer, such as Somat

defoamer, or any of a number
of commercial preparations.
C. Corrosion - If the water and/or the waste are acidic or alkaline, use a
buffering agent to neutralize the water. Regular testing is recommended,
since rapid corrosion due to acidic or alkaline conditions can result in costly
repairs.
D. Freezing - All equipment and piping should be protected from freezing.
Insulation and heating cable are often used where equipment is exposed.
E. Non-Pulpables - The SOMAT

Pulper is designed to handle a limited
amount of non-pulpable material. The lighter items are eventually ground
and the heavier material is discharged into the junk box. However, the
SOMAT

Pulper is not designed to handle heavy masonry materials or
tramp iron and other materials of this nature. Such items will break away
the cutting teeth and seriously reduce the machine's ability to handle
material of any kind.
OPERATING INSTRUCTIONS
Occasionally, the amounts of non-pulpables may become excessive and,
due to their slower processing rate, create a material build-up in the Pulper
tank. Safely stop the Pulper, scoop out the non-pulpable matter, and then
re-start the Pulper.
F. Wear - Moving parts, and their mating surfaces, will wear with service,
especially those which are part of cutting mechanisms. Your routine
maintenance and inspection, as described in the applicable component
sections, will disclose which parts are wearing and provide an indication as
to when replacement will be necessary. The maintenance plan should
include pre-ordering of spare parts and scheduled replacement.
Rotating blades may be re-sharpened. To remove blades please follow
instructions located in the “Cutting Mechanism” section of this manual.
