DESCRIPTION


LP model granulators are designed for robot or conveyor fedsprues, runners, and light duty parts. The LP granulator shouldnot be batch fed.

Primarily designed for beside-the-press applications, the LPgranulators have a low infeed height for closed-looprobot/granulator systems. The low rotor speed provides betterregrind, less noise, reduced flyback, and less wear with abra-sive material.

JC model granulators are designed for batch fed parts and run-ners and tough applications. The JC granulator may be usedbeside the processing machine or in a central granulationapplication.

Primarily designed for engineered materials, thick cross sec-tion parts and runners, the JC granulator produces a higherthroughput per hour and requires less horsepower than a con-ventional 3-blade rotor, due to the standard flywheel coupledto the helical rotor.

● Do NOT feed large lumps or purg-ings.

● Do NOT allow bin to overfill.

● Do NOT batch feed LP series.

● Always start machine BEFORE feeding material.

● Only feed in the proper amount that the granulator is sizedfor and capable of granulating.

● Allow machine to purge BEFORE turning OFF.

● Periodically inspect knives for wear and proper clearance.Adjust, sharpen or replace as necessary. Failure to do thiscould affect performance.

● Rotate the screen to extend screen life. The screen willshow washout on the holes on one side if this is not done.

SAFEOPERATINGPRECAUTIONS

LP and JC Series Beside-the-Press Granulators UGG002/09984-2 OPERATION

IMPORTANT: When using your own method of regrindremoval, the rate of material throughput shouldNEVER exceed the rate of removal, or jam-ups withinthe granulator will occur. We recommend a high levelproximity switch if bin overfill is a problem.

Inspect and clean the granulator.See the Pre-Operation Test and Inspectionprocedures inthe Installation section.

After inspection, close machine completely.

If a blower is being used to evacuate, startblower motor first. To do this, press BLOWERSTART button.

Start rotor motor by pressing ROTOR START button.

Begin feeding material slowly at firstto determinethe maximum amount machine is capable of granulatingwithout overfeeding.

Stop the rotor motor first. To stop the rotor motor,press the ROTOR STOP button.

If a blower is being used to evacuate, stop theblower motor 30 seconds AFTER stopping therotor motor. To stop the blower motor, press theBLOWER STOP button. Doing this ensures all granulatedmaterial is purged, thus eliminating jam ups within thecutting chamber and/or blower system.

● Periodically, inspect knives for wear and proper clearance.Adjust, sharpen or replace as necessary. Keep the knivessharp at all times.

● Rotate the rotating end disc 180 degrees at blade sharpen-ing interval to extend disc life.

● Grease the outboard rotor shaft bearing every three (3)months or as required. Do NOT over grease. Damage tothe bearing seal could result.

● Periodically inspect all nuts, bolts and screws to ensurethat none have become loose due to operation.

● Inspect the cutting chamber about every 3 months to makesure that material is not getting caught between the enddiscs and the chamber walls.

To replace the helical segments, see the following sets ofinstructions.
