NBE drum lift carriages are engineered for high-performance operation; the pneumatic drum-centering system on NBE drum discharger buckets minimizes drum handling by operators, increasing the physical ergonomic benefits of the equipment and improving the material discharge accuracy.

Material Discharge Hoods and Diverters

NBE drum dischargers bring immediate advantage to process operations by specifically designing and engineering the material discharge hood to the particular integration requirements of the application; eliminating the need to force fit stock hoods, or attempt aftermarket fabrication. NBE drum discharger hoods, aid material infeed flow, protect the product and process from contaminants, and prevent dusted material from becoming airborne throughout the facility. NBE discharge hood designs may integrate material-present sensing, and machine interface configurations custom to downstream equipment.

Safety Cage and Light Curtain Systems

NBE drum dischargers undergo comprehensive risk assessments and design reviews to ensure the drum discharging system is engineered to provide safe operation. Beyond the safety features inherent in the structural design, additional guarding such as safety cages and light curtains are integrated to NBE drum discharging systems to aid in protecting personnel during equipment operation and maintenance.

Hydraulic Systems

NBE drum discharger lift carriages are hydraulically driven to ensure high-performance handling of drums or barrels; regardless of the container weight, process lift height, carriage rotation, or duty cycles of the application. The hydraulic power unit and valve stack of an NBE drum discharging system are engineered to the required cycles per hour, and per-cycle duration for the application. NBE drum discharger hydraulic systems are constructed for general industrial material unloading applications; as well as wash-down duty, intrinsically safe, and explosion-proof classifications.

Open-Bucket Drum Dischargers

Open-bucket drum dischargers provide highly effective unloading of non-dusting materials. NBE drum lift carriages and buckets are engineered to specific drum or barrel requirements; regardless of size, weight, or materials of construction.
Sealed Drum Dischargers

For applications with stringent material dust control requirements, NBE sealed and enclosed drum discharge systems prevent material dust from escaping and creating an airborne nuisance. The NBE drum sealing design hydraulically lifts and seals the top edge of the drum into the discharge hood, preventing foreign material on pallets or containers from contaminating the material stream.
Direct-Discharge Systems

Direct-discharge systems are engineered with an application-specific interface to enable the interconnection of the NBE drum discharger directly to process equipment. The NBE direct-discharge design helps to protect operators, while increasing infeed efficiency and reducing material waste.
High-lift Drum Dischargers

High-lift drum discharging systems safely raised containers from floor-level load position to high-level discharge heights. The NBE high-lift drum discharge system, using a hydraulically driven track-and-cam roller mechanism, vertically conveys drums or barrels, in excess of 750 pounds, to discharge heights exceeding 25 feet. NBE high-lift discharging systems provide drum rotations to 180 degrees; ensuring complete material discharge; regardless of drum type.

Other Drum Discharger Configurations

General Industrial Construction

NBE drum discharger systems are designed for rigorous duty in critical applications. Every NBE drum discharger, regardless of its particular design or application, operates on a process-specific, fully welded structural framework; unlike common bolt-together unloader designs. The standard support framework of an NBE drum discharger is constructed of heavy-duty structural steel and/or tubular steel that is continuous welded to provide superior structural integrity.
Sanitary / Hygienic Construction

NBE sanitary drum discharger systems are engineered and constructed to the particular requirements of each applications where compliance with regulatory, governmental, or industry-based hygienic design standards is necessary. NBE drum dischargers meet, or exceed, materials of construction, build specifications, and process protocols where third-party standards are required. NBE sanitary drum and barrel discharger designs includes CIP features, such as: continuous-weld seams ground to a No. 4 finish,304-2b stainless steel construction, and tool-less, quick-clean component designs to simplify sanitizing and inspection.
Wash Down Construction

The materials of construction and build specifications for NBE drum dischargers operating in wash down applications includes structural framework beams and cross members that are of tubular construction with all ends capped and no holes protruding to the inside of any tubing. Beams and cross members on NBE drum dischargers are angled away from product zones, or turned 45 degrees to horizontal, to aid in preventing material accumulation and pooling of liquids.
Lift-and-Discharge Construction

For applications requiring elevating, rotating, and discharging the drum at height; NBE high-lift discharging systems provides safe and stable drum handling. The drum or barrel is raised using a hydraulically driven track-and-cam roller mechanism that eliminates side-to-side racking, and vertically conveys containers, in excess of 750 pounds, to discharge heights exceeding 25 feet. A mast cylinder guide race stabilizes the cylinder rod, eliminating potential damage to the rod and seal. All moving hydraulic hose, pneumatic tubing, and electrical Sealtite® conduit are contained in flexible cable carriers for protection during operation.

Other Drum Discharger Frameworks

Control Enclosures

NBE drum discharging system control enclosures are custom-built in a dedicated, on-site, UL certified panel-build facility. Panel configurations include UL 508A, Class I and II, Division 1 and 2, Group A-D, F and G, and NEMA 12 enclosures with Type X purge.
PLC Programming

The complete operating sequence of an NBE drum discharger functions from a process-specific automation and controls architecture centralized to a single, menu-driven, touchscreen HMI. NBE drum discharging system automation and controls provide intuitive HMI screen layouts, straightforward fault monitoring and recovery, and comprehensive data reporting.
Device Wiring

NBE bulk drum discharger systems are plumbed using custom-formed, rigid conduit and flexible, poly-tubing. Numbered, or color-coded wires are pulled and secured to terminals between devices, junction boxes, main control component enclosures, and operator control stations. Color-coded poly-tubing simplifies troubleshooting and maintenance of the equipment.

Other Automation and Control Systems

Power Unit and Valve Stacks

Hydraulic system power units include a large reservoir with a return line filter, sight gauge, and vented fill cap. Power units are mounted to the framework of the NBE drum discharger. Skid-mounted power units are also available.
Drum Seal Cylinders

For NBE drum discharge systems with the drum lift-and-seal feature, a hydraulic cylinder raises the lift carriage, with the drum, to seal the top edge of the drum into the internal flange of the discharge hood. The NBE lift-and-seal feature prevents foreign material on pallets or drums from contaminating the material stream.
Rotational Cylinders

Rotation cylinders provide the inversion actuation to the drum lift carriage; up to a 180-degree rotation. The NBE rotation cylinders also revert the lift carriage, and the drum, to their pre-inverted position in the discharge sequence of operation.
Mast Cylinders

Mast cylinders deliver hydraulic actuation required to safely raise the lift carriage and drum to the discharge height. NBE drum discharging systems use a hydraulically driven mast cylinder, together with a carriage track-and-cam roller system, to eliminate side-to-side racking, and vertically convey drums, in excess of 750 pounds, to discharge heights exceeding 25 feet.
Rotolink™

NBE Rotolink™ is a 3-bar mechanical linkage that provides a smooth, continuous-speed, 180-degree rotation of the lift carriage and drum. The NBE Rotolink feature uses a specific geometry, calculated for the specific application, to provide optimal balance and consistent force and velocity during the rotation action of the lift carriage and drum.
