Asphalt Drum Mixers’ Weigh Conveyors Ensure Precise Asphalt Mix

ADM_ConveyorHUNTERTOWN, Ind. — Asphalt Drum Mixers, Inc., offers portable and stationary weigh conveyors, which are compatible with both its own and similar competitive models of asphalt plants. Weigh conveyors transfer material from cold feed bins into the drum and are designed to give an accurate weight measurement of the aggregate, allowing operators to achieve an optimum asphalt mix. Five models are available with various dimensions to meet the demands of many operations.

ADM’s weigh conveyors are available in truss or C-channel frame configurations. The drive system features an 1,800-rpm high efficiency motor, head-shaft-mounted gearbox, V-belt drives and high performance pulleys and idlers. Open-mesh safeguards protect the belt drives, and a sensor on the tensioning idler monitors the speed. The conveyor also includes an adjustable self-cleaning winged tail idler assembly, and the head section contains a spring-tensioned polyurethane belt scraper.

A concentric cam vibrates the unit’s scalper screen, which has 1.5-inch square openings to ensure that oversized material does not enter the drum. Material that is too large to pass is directed to the divert/reject chute. A double-deck scalper screen with pneumatic deck selection is an available option.

The conveyor’s weighbridge features an NTEP-approved high capacity load cell and is engineered to provide precise measurements. A shroud eliminates wind interference, while the gravity take-up system keeps the multi-ply belt in contact with the weighbridge at all times.

Portable units are transported on a single-axle trailer with a pintle ring hitch for easy towing. The smallest model uses electric brakes, and all other models feature air brakes.

A family-owned company since 1974, Asphalt Drum Mixers, Inc. offers asphalt plants, auxiliary equipment, parts and service.
