Trough / Pan: Capacity 5-1000 t/h, Width 200-1500 mm

Component Specifications

Definition

The trough or pan is the primary conveying surface of a vibrating feeder, designed to transport bulk materials from a storage hopper to downstream processes. It consists of a rigid, open-top container mounted on springs or flexible supports that allow controlled oscillatory motion. The component's geometry, material composition, and vibration characteristics determine its capacity, flow rate, and material handling efficiency in industrial applications.

Working Principle

The trough/pan operates on the principle of controlled linear or elliptical vibration generated by electromagnetic or mechanical exciters. This vibration causes material particles to hop forward along the pan surface in a series of small throws, creating a continuous flow. The angle of inclination, vibration frequency (typically 15-60 Hz), and amplitude (0.5-10 mm) are precisely controlled to achieve desired throughput rates while minimizing energy consumption and material degradation.

Materials

Carbon steel (ASTM A36/A572), Stainless steel (304/316L), Abrasion-resistant steel (AR400/500), Aluminum alloys (6061-T6), Polyurethane or rubber liners (for noise reduction and wear protection)
