GENERAL
ARMCON PROGRESSIVE SHREDDER MILL IS A ROBUST AND RELATIVELY MAINTENANCE
FREE SHREDDING MILL IDEAL FOR EMPTY FRUIT BRANCHESAND PALM OIL FRONDS FROM
PALM OIL MILLS AND THE LIKE. IT WORKS ON THE PRINCIPLE OF PULPING AND TEARING
INSTEAD OF CUTTING THE FEED.
PRINCIPLE FEATURES OF THE MILL IS ITS RELATIVELY SIMPLE DESIGN MADE UP OF A
PROGRESSIVELY VARIED TEARING EDGE AND A WORKING TABLE TO THROW THE FEED
TOWARDS A BACK PLATE FOR PULPING AFTER WHICH TEARING OF THE PULP IS EFFECTED.
THESE OPERATIONS ARE DONE COMPLETELY IN 1 SINGLE CHAMBER.
HIGHLIGHTS
•PROGRESSIVE CUTTING BY HELICAL ROTOR ENSURES CLEAN SHEAR WITH LOWER
ENERGY REQUIREMENTS.
•ROTOR UNIT IS FORMED FROM A FLAT SURFACE WITHOUT OPENINGS FOR SHRED FIBRES
TO ENTANGLE SHAFT THERBY CAUSING LOCKUP AND JAMMING.
•REPLACEMENT ‘BLADES’ ARE VERY ECONOMICAL FLAT CARBON STEEL PLATES WITHOUT
THE NEED TO SHARPEN. THE ‘BALDES ARE MORE TO PROTECT THE YORK OF THE ROTOR
AGAINST ACIDITY OF SHRED MATERIAL.
•THE MILL SHELLS (TOP /BOTTOM) ARE CAST HIGH TENSILE STEELS TO ABSORB IMPACKS
FROM THE PULPING OPERATIONS.
•TWIN PULLEYS ACT ALSO AS FLYWHEELS FOR SMOOTH OPERATIONS AND SURGES.
INSTALLATION OF MOTORS CAN BE ON ANYSIDE OF THE MILL AS REQUIRED. THIS
PROVIDES EASY INSSTALLATION WITHOUT CAVEATS.

INSTALLATION
INSTALLATION OF MILL IS EXTREMELY SIMPLE. CONSULT CONTRACTORS FOR THE
PLATFORM OF WHERE THE OUTLET HOLE IS LOCATED. THE MILL SLOULD BE SITTING ON
THE U BEAMS AROUND THE HOLE (SEE DRAWINGS PROVIDED)
•LIFT THE MILL TO SIT ON THE LOCATING DESIGNATED
•BOLT DOWN WITH 4 Nos. 25mmØ HIGHTENSILE BOLTS AND NUTS
•WELD THE DROP SKIRT TO COVER ALL U BEAMS UNDER THE PLATFORM AND MILL
OUTLET. THIS IS VERY IMPORTANT TO PREVENT SHRED FIBRE BUILDUP TOWARDS
THE BOTTOM GRILL WHEREBY THE MILL WILL JAM OVERTIME.
•INSTALL THE MOTOR AND BELTS ON WHICHEVER SIDE OF THE PULLEY AS REQUIRED.
•INSTALL THE DROPDOWN CHUTE OVER THE FEED HOLE.
•INSTALL THE DISTRIBUTOR CONVEYOR TO DROP INTO THE DROP CHUTE.
•MANUALLY TURN THE ROTOR BY PULLING AT THE V-BELTS. CHECK FOR SCRAPPING
SOUNDS. THERE SHOULD NOT BE SCRAPPIING AS THE MILL IS SET AT THE FACTORY.
INFORM ARMCON SHOULD THERE BE SCRAPPING.
•RUN THE MILL EMPTY FOR 15 min.
•THE MILL IS NOW READY FOR PRODUCTION.
•THE MILL IS VERY ROBUST. SHOULD THERE BE ANY JAMS DURING OPERATION, JUST
STOP THE MILL, REMOVE THE SIDE COVERS AND CLEAR THE FIBRES. CLOSE BACK ALL
COVERS AND THE MILL WOULD RUN AGAIN.
DISMANTLING OF SHREDDER MILL
DISMANTLING OF COMPONENTS IS EXTREMELY SIMPLE. KINDLY FOLLOW THE STEPS BELOW FOR
REMOVAL OF SHREDDER PARTS.
PULLEYS/FLYWHEELS ARE LOCKED USING TAPER LOCK BUSH. TO REMOVE, RELEASE JAM BOLTS
TO RELEASE GRIP ON SHAFT. USE A MALET TO KNOCK OUT THE PULLEY.
STEP 1,
REMOVE TOP HOUSING.
STEP 2,
RELEASE HOLDDOWN BOLTS FOR BOTH
PLUMMER BLOCK BEARINGS. LIFT UP PROGRESSIVE
CUTTER AS A COMPLETE UNIT.
TAPER
LOCK
TO REPLACE BEARINGS, UNLOCK TAPER LOCK BUSH
ON BOTH PULLEY/FLYWHEEL. REMOVE PULLEY AND
BEARINGS. REASSEMBLE AFTER REPLACEMENT.
STEP 3,
REMOVE GRILL BY REMOVING HOLDDOWN BOLTS.REPLACE
GRILL IF NECESSARY. REASSEMBLE.
TO ASSEMBLE SHREDDER MILL, FOLLOW STEPS 1-3 IN REVERSE ORDER
