DLJML / DLJGDLJML / DLJG / DLBYX / DLMFY / DLMBYS Gear Units for Mill
Mill Gearboxes DONLY DLJML / DLJG
Five Donly mill gear unit series. DLJML for vertical mills: bevel + planetary (X), bevel + helical + planetary (XSD) or bevel + two planetary (XSS) stages; nominal power 100–8,000 kW (code = 1/10 of power, X10…XSS800), i = 18–55, vertical load on the output flange 450–16,500 kN, Klingelnberg bevel sets. DLJG planetary units for roller presses with multi-path power split, efficiency > 0.96. DLBYX single-stage girth-gear pinion drives for ball mills, DLMFY central drives (2–3 stages), DLMBYS girth drives for 800–5,600 kW mills.
