Sugar Mill Applications

Core Applications in Sugar Plants

• Main Tandem Mill Drives & Gearboxes: The massive crushing rollers that shred raw sugarcane stalks handle intense torque and shock loads. They rely on highly viscous lubricants (typically ISO VG 460 or 680 extreme-pressure oils). Offline filtration units must handle these heavy fluids to clear out abrasive wear particles and fine bagasse pulp that pass-through shaft seals.
• Mill Roll Bearings (Cane Crushers): Heavy-duty bearings on cane crushers operate under constant exposure to sprayed wash water and raw sugarcane juice. Juice contamination creates acidic byproducts, chemically shearing the oil. Vacuum dehydration systems are essential here to draw out moisture and neutralize acidity.
• Hydraulic Juice Extraction & Gate Power Packs: Modern sugar mills utilize high-pressure hydraulic cylinders to control roller feeding and feed-gate positioning. Offline micro-filters maintain oil cleanliness down to an absolute NAS 6 rating, preventing servo/proportional valves from sticking.
• Co-Generation Steam Turbines: Most large Indian sugar plants generate their own power by burning bagasse in boilers to drive steam turbines. Turbine oil loops are prone to water condensation from steam leaks. Dedicated purifiers continuously pull water down under 100 ppm to prevent bearing wipeouts.
