Product Overview

The Ultra-Wide Weighing Belt Conveyor is a heavy-duty, continuous totalizing automatic weighing instrument featuring a belt width of 1200 mm or greater and a multi-point array weigh deck structure. It seamlessly integrates continuous bulk material conveying, dynamic inline weighing, and variable-frequency quantitative feeding into a single system. Utilizing gravimetric load sensing combined with digital velocity calculation, it provides real-time monitoring of both instantaneous mass flow rates and cumulative totalized weight. This system is ideally optimized for high-capacity bulk material blending, batching, and commercial custody transfer.

Operating Principle

Through a symmetrically balanced structural frame, multi-point power distribution, automatic belt tracking, and constant tension control, this system effectively mitigates common operational issues-such as belt mistracking, belt surface wave deformation, uneven load distribution, and localized overloading-that typically plague conventional conveyors under ultra-wide (usually ≥ 3m), heavy-duty, and long-distance operating conditions. This ensures smooth, centered, and low-stress continuous belt conveying.

Conveyor Belt: Ultra-wide, high-tensile, symmetrically cored belt (PVC) featuring exceptional lateral stiffness, high tear resistance, and anti-deformation properties.

Idler Assemblies: Equidistant, symmetrical, high-precision idler sets with a coaxiality and alignment tolerance of ≤ 0.5 mm/m to guarantee stable and level belt travel.

Drive System: Synchronized dual-motor drive paired with variable frequency control, maintaining a speed differential of ≤ ±0.5% for perfectly balanced power distribution.

Structural Frame: Rigid, symmetrical box-girder or truss structure engineered to minimize deflection and maintain strict centerline alignment across the entire conveyor length.

Tensioning & Tracking: A triple-protection centering system combining dual-end synchronized tensioning, self-aligning idlers, and mechanical anti-drift tracking guards.
