Convoyeurs alimentation à bande

Historiquement, les alimentateurs à bande ont été utilisés dans de nombreuses applications et constituent généralement une solution rentable, facile à entretenir.

Dans certains cas, les alimentateurs à bande sont sujets au déraillement, où la bande dévie sur un côté. Dans de tels cas, un alimentateur à profil bas sera une solution plus appropriée car il élimine complètement le déraillement.

A feeder controls the rate material leaves storage; a conveyor simply moves material at a fixed rate. A feeder is flood-loaded, with its speed setting the discharge rate from a hopper or bin, while a conveyor runs at a fixed, higher speed while only partially full. Transmin has designed bespoke belt feeders for this role since 1987, handling everything from coarse dry ore to fine, wet filter cake.

Belt feeders typically mis-track due to off-centre loading, poor splice alignment, uneven belt wear or structural misalignment. Other common causes include harder or tighter skirt rubber on one side, material build-up on the pulley, uneven scraper pressure, and product characteristics such as sticky or unevenly distributed material. Regular inspection and correct alignment of the feeder components can help prevent tracking issues.

Head load is the weight of material pressing on the belt beneath the hopper, and it’s the biggest factor in sizing a belt feeder’s drive and structure. More head load means more installed power and heavier-duty components. Transmin manages this through hopper design and by engineering the feeder, hopper transition and isolation gate as one matched package.
