The milling tandem

The milling tandem consists of the following:

• Mill No. 1 is a 7-foot three-roll mill (1995) with Donnelly chute and a 2,500 hp multi-stage turbine driving Horsburgh & Scott gearboxes. Roll diameters: 46 inches.
• Mill Nos. 2 and 3 are 6.5-foot mills with force-feed rolls and 40-inch roll diameters.
• Mill No. 4 is a 7-foot mill driven by Hagglunds hydraulics (MB1150 and MB566 motors) powered by a 1,200 hp Elliott turbine and David Brown gearbox. Roll diameters: 44 inches.
• Mill No. 5 is a 7-foot mill with 44-inch rolls, powered by a 1,400 hp Elliott turbine and Horsburgh & Scott gearboxes, featuring an offside crown wheel force-feed roll.
• Mill No. 6 is a Skoda mill with 7-foot by 48-inch rolls, driven by a 2,500 hp multi-stage turbine and offside crown wheel force-feed roll.

All six mills use Donnelly chutes with probe-controlled feed rates and rubber-belt conveyors set at 60°. Grooving is tuned to each mill: the first three use 3-inch pitch, 45° grooves; the last three use 2-inch pitch, 45° grooves. All cane rolls include messchaert juice grooves measuring 1/2 inch by 1 inch.
