SUGAR TECHNOLOGY & INNOVATION

INCREASE IN MECHANICAL EFFICIENCY RR TASKS Cane juice extraction is the most power demanding step in the sugar process. Reggiana Ridutto has developped an innovative mill rollers drive system, succeeding in following tasks: INCREASE IN MECHANICAL EFFICIENCY INVESTMENTS REDUCTION (CONSTRUCTION and MAINTENANCE) EXTRACTION CONTROL CONVENTIONAL MILLS UPGRADING Let’s see HOW

INCREASE IN MECHANICAL EFFICIENCY CONVENTIONAL MILL DRIVE foot-mounted reduction gearings with tail bar, crown pinions and rope couplings does it easier with its INNOVATIVE PINIONLESS MILL DRIVE consisting of SHAFT MOUNTED GEARBOXES DIRECTLY ON THE ROLLER SHAFT

INCREASE IN MECHANICAL EFFICIENCY CONVENTIONAL DRIVE Crown pinion 92% Tail bar 97% High speed reducer 90% VFD Electric motor 96% EQUIPMENTS PINIONLESS DRIVE CONVENTIONAL MILL AC Motor 96% REDUCTION GEARS 95% 92% Low speed OPEN GEAR 60% Tail Bar 97% CROWN PINION TOTAL EFFICIENCY 47% WIN 200% MORE EFFICIENCY WITH PINIONLESS DRIVE 91%

INCREASE IN MECHANICAL EFFICIENCY ROPE COUPLING DRIVE 15% MORE EFFICIENT THAN COMMONLY USED PLANETARY DRIVE EQUIPMENTS PINIONLESS DRIVE ROPE COUPLING MILL AC Motor 96% REDUCTION GEARS 95% 92% Rope coupling 97% CROWN PINION TOTAL EFFICIENCY 91% 79%

INCREASE IN MECHANICAL EFFICIENCY RR EXPERIENCE: 4 MILLS 40” x 80”, 6000 TCD. MILLING SPEED: 4,5 rpm INSTALLED POWER: 840 kW/mill. 2 X 250 kW TOP ROLLER (RR55000) 1 X 250 kW BOTTOM ROLLER (RR55000) 1 X 90 kW TRF (RR25000) POWER SAVING WITH PINIONLESS DRIVE: 100 kW/mill 100 kW/mill 400 kW/day 72 MW/Season (6 months)

INVESTMENTS REDUCTION SHAFT MOUNTED GEARBOXES NO NEED OF FOUNDATIONS COMPACT FACTORY DESIGN

INVESTMENTS REDUCTION SPLITTED POWER SMALLER GEARBOXES and MOTORS SIZE BETTER AVAILABILITY and LOWER SPARE PART PRICES SHORTER POWER TRASMISSION CHAIN LESS MAINTENANCE REDUCED SPARE PARTS STOCK

INDIPENDENTLY DRIVEN ROLLERS EXTRACTION CONTROL FLEXIBLE ROLLERS RELATIVE SPEED SET UP BETTER CANE FIBERS SHREAD and COMPRESSION CONTROL ROLLER SPEED RATIOS can be RELATED TO CANE QUANTITY, QUALITY and DENSITY INDIPENDENTLY DRIVEN ROLLERS SMARTER MILL SET UP BETTER EXTRACTION CONTROL

EXTRACTION CONTROL TORQUE TRASMISSION BETWEEN CROWN PINIONS CAUSES a LOCAL REACTION and HIGH STRESS LEVELS at MILL ROLLERS END HIGH STRESS LEVEL at MILL ROLLER SHAFT END FREQUENT FAILURE and WEAR OUT of: CROWN PINIONS BRASSES BEARINGS UNSYMMETRICAL ROLL LIFT NOT UNIFORM CANE BLANCKET COMPRESSION LOWER EXTRACTION EFFICIENCY WITH PINIONLESS DRIVE UNIFORM CANE BLANCKET COMPRESSION LONGER COMPONENTS LIFETIME LESS MAINTENANCE

INDIVIDUAL PINIONLESS ROLL EXTRACTION CONTROL INDIVIDUAL PINIONLESS ROLL DRIVE POWER ABSORPTION AND ROLL SPEED CONTROL DRIVE FOLLOWS THE ROLL MOVEMENT UNIFORM ROLL LIFT and LOWER STRESS LEVEL (no pinion reaction) BETTER EXTRACTION REDUCED WEAR LESS MAINTENANCE

CONVENTIONAL MILLS UPGRADING PINIONLESS DESIGN CAN CONVERT CONVENTIONAL MILLS INTO MODERN PINIONLESS MILLS AND TAKE ADVANTAGE OF MOST TECHNICAL ADVANTAGES FLANGE TO FLANGE ASSEMBLY CAN UPGRADE THE TRADITIONAL ROLL DRIVES INTO SHAFT MOUNTED GEARBOXES. YOU CAN IMPROVE EXISTING SUGAR PLANTS ENERGY LEVEL TO THE MOST MODERN STANDARDS end GAIN BETTER EXTRACTION
