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

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
