A range of square and round outlet valves are available as shut-off gates for the gravity flow of granular, powdered bulk solids from bins and hoppers. A full range of this equipment in standard and heavy-duty construction is fabricated in manual, pneumatic and motorised versions.

COAL FEEDER - Variation of the knife gate

Used to provide a dust-tight shut-off for discharge spouts on silos and for controlled discharge of pulverised bulk material. Control is achieved through an internally rotating roller-shaped gate.

These gates are ideal for rapid discharge of bulk materials from bins and hoppers and can be manually or pneumatically operated.

This equipment is specifically designed to stop or adjust the flow of materials such as ore, rock and minerals.
