Tubular feeders
Tubular feeders are suitable for handling and dosing of free flowing bulk material with a max. grain size of 1/3 of the tube diameter. Especially when the conveying process has to be dust free, tubular feeders are suitable through their closed design; which is needed also with high standards of hygiene and cleanliness. For feeding poisonous and hazardous substances, tube conveyors are used preferred.
Advantages and benefits
Wide range of applications:
- conveying
- feeding
- bin / hopper discharging
- driven by magnetic vibrator/s or unbalanced motor/s
- dustproof
- long distances possible due to serial connection of feeders possible (conveyor lines)
- multiple drive possible (magnetic vibrators)
- variants available for reversing machines
- separate replacement of tube body or drive traverse (clamp version)
- made of mild steel or stainless steel
Construction
Tube feeders are characterized by their simple design. The main components are:
- feeding tube with a drive beam, either welded or connected by clamping saddle
- drive (magnetic vibrator/s or unbalanced motor/s)
- inlet / outlet nozzles
- elastically supports
- flexible sealing
Selection
The sizing is dependent on:
- product to transport
- throughput
- required geometry
- possible installation space
Key figures
- length: up to 7,000 mm for single machines, theoretically unlimited for conveyor lines
- diameters: 219 mm, 273 mm, 324 mm, 406 mm as standard, other diameters possible
- throughput: up to approximately 80 m3/h
- drives: magnetic vibrator or unbalanced motor
