Stable, accurate feeding is the foundation of efficient bulk solid processing. For many production lines, ordinary open-type vibrating feeders struggle with material scattering, flow fluctuation, and inconvenient on-off control. Our Tube Electromagnetic Vibrating Feeder delivers enclosed tubular conveying, infinitely variable throughput and reliable material shut-off, solving common feeding challenges for powder and granular materials.

Core Product Specifications

• Conveying Capacity: 0 ~ 80 TPH
• Main Body Material: Mild Steel
• Speed Regulation: VRV controller supporting stepless variable flow
• Auxiliary Control: Pneumatic cylinder valve mounted at tube outlet for rapid material cut-off
• Inlet design: Tapered hopper inlet to centrally receive material from upstream equipment

Key Design Advantages

1. Enclosed Tubular Structure Avoids Material Spillage

Different from traditional open electromagnetic feeders, this tubular vibrating feeder adopts a fully enclosed mild steel tube structure. Dust leakage and material scattering are greatly reduced, creating a cleaner working environment. The sturdy mild steel construction delivers long service life under continuous vibration conditions, suitable for long-term industrial operation.

2. VRV Controller Achieves Stepless Flow Adjustment

The feeding capacity can be flexibly adjusted within the range of 0 to 80 tonnes per hour. Matched with our dedicated VRV controller, operators realize smooth, stepless speed regulation. The throughput can be fine-tuned online according to downstream production demands, ensuring consistent and stable material supply without abrupt flow changes.

3. Pneumatic Cylinder Valve for Accurate On-off Control

A built-in pneumatic cylinder valve is installed on the front section of the tubular body.

When temporary stop of feeding is required, the cylinder drives the valve to quickly cut off material flow. This feature brings outstanding precision for batching, weighing and intermittent production processes, avoiding excess material overflow.

4. Tapered Inlet Hopper for Stable Material Receiving

The top inlet adopts a tapered converging structure. It efficiently collects material discharged from upstream silos or conveyors, guiding bulk materials smoothly into the vibrating tube and preventing material accumulation at the feeding port.

Working Principle

The Tube Electromagnetic Vibrating Feeder relies on electromagnetic excitation to generate micro vibration of the enclosed tube. Bulk materials move forward continuously inside the tubular channel under vibration. By adjusting the output signal via the VRV controller, vibration amplitude changes, so the material conveying speed and hourly throughput can be modified continuously. Combined with the front cylinder valve, users gain dual control of flow rate and material switch.

Typical Application Scenarios

This enclosed tube electromagnetic vibrating feeder is widely applied for granular and powdery bulk materials including silica sand, minerals, quartz sand, chemical raw materials and dry granular materials. It fits perfectly in glass manufacturing, mineral processing, chemical industry and building material production lines.
