Tubular Vibratory Feeder: Enclosed Dust-Free Vibrating Tube Conveyor for Bulk Material Handling

When handling fine powder, granular and friable bulk solids in production lines, dust leakage, material contamination, uneven feeding and difficult material diversion are among the most common headaches for plant engineers.

Traditional open trough vibratory feeders often generate fugitive dust, which brings environmental risks, product pollution and extra maintenance cost. Split conveying pipelines and rotary valves for material splitting usually lead to material blockage and high wear rate.

That is where our VRV Tubular Vibratory Feeder stands out.

Also known as a vibrating tube feeder or tubular vibrating conveyor, this enclosed vibratory feeding equipment adopts a fully sealed tubular structure driven by vibratory motors. Different from conventional straight tube vibratory conveyors, our model supports customized multi-inlet and multi-outlet layout. It can realize one inlet with two outlets or two inlets combined into one outlet, which is ideal for material diversion, merging and proportional feeding within one compact unit.

Core Advantages of VRV Tubular Vibratory Feeder

✅ Fully enclosed tubular housing for zero dust escape

The welded sealed tube body with flange connections keeps all materials inside the pipeline. No dust spillage, suitable for toxic, fine, hygroscopic or valuable powder materials. It meets strict dust control requirements for workshop environmental protection.

✅ Gentle vibratory conveying, no material damage

Material moves along the tube through micro-throw vibration. No screw shearing, no particle crushing. Perfect for fragile granules, food grains, chemical crystals and positive electrode & negative electrode powder for lithium batteries.

✅ Flexible multi-port configuration for process diversion

One single tube feeder can be equipped with 2~3 flanged ports. Engineers can arrange feeding paths according to process flow, saving extra diverter valves and pipeline space, cutting your whole system investment.

✅ Stepless adjustable feeding capacity

The vibration amplitude and feeding rate can be adjusted continuously via control box. Stable dosing for continuous batching and quantitative feeding.

✅ Easy maintenance & sanitary optional design

Quick-release isolation mounts, smooth internal surface. We provide carbon steel, Q235, 304 stainless steel and wear-resistant NM400 lining options. PU or UPE lining is available for non-contamination demand. IP65 vibratory motor is standard.

✅ Low noise, low power consumption

Vibration isolation springs effectively reduce vibration transmission to supporting frames and floors. Low running noise for indoor production workshops.

Typical Application Industries

Our enclosed tubular vibratory feeder is widely adopted for bulk material dosing and conveying:

FAQ

Q: What is a tubular vibratory feeder used for? A: It is an enclosed vibratory feeding machine for powder and granular bulk solids, used for dosing, conveying, diverting or merging materials without dust leakage.

Q: What is the difference between tubular vibratory feeder and trough vibratory feeder? A: Tubular type is fully sealed for dust control; Most trough type is open. The tube version is preferred for fine powder and hazardous materials.

Q: Can the tubular vibrating feeder split material flow? A: Yes. Our VRV model supports multi-port design to realize one inlet two outlets for material diversion.

Q: Is stainless steel tubular vibratory feeder available for food grade? A: Yes, we offer 304 stainless steel body and PU lining for food and hygienic applications.
