A COMPARISON
• Full torque at any speed gives advantages in milling efficiency:– Higher Extraction
– Lower Moisture
– Lower POL
– Lower Power Consumption
• High controllability• Full speed variation• Quick Response to keep mill always loaded

Optimising operating conditions
• Excellent controllabilityThe feeder rollers are driven independently from the same mill
• Ideal throughput and best extractionThe excellent controllability enables related cane load and adjusted feed to the mill
• Space and weight saving Motors with the best power-to-weight ratio available
