Rust-stained conical hoppers drop toward a horizontal trough conveyor running across the mid-ground at Kandos Cement Works, the whole assembly suspended above a grated steel floor patterned with shadow. Orange electrical cabling traces the overhead beams, and a blue emergency light panel sits mounted to the right of the central hopper. Dust and debris have settled across every horizontal surface.

03 THE STORY

About this print

A screw conveyor at Kandos Cement Works runs along the underside of one of the mill bays, carrying material laterally between two points in the cement-making circuit. The conveyor is housed in a long steel trough with a bolted lid, hung from the structural steel above on threaded rods. The drive motor at one end sits on a small bracket, coupled to the screw shaft through a reduction gearbox. Cement dust has settled on the upper surfaces of the trough and along the joins where the access plates seat against their gaskets. The trough is darkened from years of operation. Light from a clerestory window above falls across the run, picking up the line of bolt heads down the lid.

A screw conveyor is one of the standard means of moving powdered material short distances in a plant of this kind. A helical screw inside a closed trough rotates, dragging the material along the trough toward the discharge end. The system is dust-tight, simple to maintain, and well suited to cement-making circuits where airtight handling matters. Kandos Cement Works ran many of these conveyors across its 95-year operational life. The plant closed in September 2011 and the screws have been still since. Most of the conveyor housings remain in place; the higher-value motor and gearbox components in some bays were removed in the decommissioning phase after closure.

04 FROM THE FIELD NOTES

Steel hoppers taper to narrow discharge points above a screw conveyor trough. The metal grating underfoot is coated in pale powder. Thick dust covers every surface. Structural beams and diagonal braces crowd the ceiling. Light enters from both ends of the corridor, catching the fine particulate still clinging to chute walls and flanges. The air feels close and dry.

The town's first name was Candos, an acronym of the directors' surnames at the NSW Cement Lime and Coal Company. They bought 100 acres from local farmer John Lloyd Junior for £2,000 in 1913 and had surveyor James Dawson lay out the township. The Postmaster General ruled the name change to Kandos in 1915, and by August 1916 the kilns at the new cement works were firing.
