Bulk Material Vibrating Spiral Conveyor

Bulk Material Vibrating Spiral Conveyor

Applications
The vertical vibrating spiral conveyor is a multifunctional conveyance unit that can be used for cooling, drying and lifting materials. These machines are widely used in the handling of plastics, chemicals, mining, and other processing industries. The maximum transport distance can reach up to 8 meters and the maximum throughput is 3t/h, which can be adjusted according to the specific operating needs of customers.

Material types
Vibrating spiral conveyors are standard equipment for many industries to elevate bulk materials. It can convey, dry and cool plastics granules, rubber granules, chemical and pharmaceutical intermediates, metal salts, welding powder, glass batch, catalysts, abrasives and ash as well as milk powder, powdered coffee, tea, nuts, nutrients and cereals.

How a bulk material vibrating spiral conveyor works
A bulk material vibrating spiral conveyor uses a vibration drive to give directional vibration to the helical trough, moving the bulk material upwards in tiny jumps. The conveying performance depends on vibration frequency, amplitude, vibration angle, helical trough structure, and material properties such as particle size, bulk density, and flowability.

Features
  • The vertical spiral conveyor is designed with an advanced spiral structure made by molding technique.
  • Spiral elevator adopts German mold forming process with stable performance and long term vibration without cracking.
  • The vibrating plate is spirally and the material can be transported uniformly along the spiral with no obvious backflow at any height.
  • When the customer wants to change the type of material that be transported, it is easy to clean. Because the inside of the tank is smooth and there is no dead corner.
  • When it convey high glass fiber reinforced material, it can effectively prevent light material from rubbing and discoloring, because the material inlet is made of stainless steel and titanium alloy.
  • The power loss is lower than the similar machines by 30%-50% after we optimized the vibration structure to achieve maximum inertial vibration.
  • The material lifter adopts special custom anti fatigue elastomer to reduce vibration. The noise is controlled at 75-80 dB when no load runs.
  • The vertical conveying unit features a parking brake design which can completely stop vibration in 2 seconds and avoid system resonance failure.
  • Its working life is long because the material of the feed and discharge parts is thickened and reinforced.
  • We can design frequency conversion control and adjust the delivery time and speed according to the actual requirements.
  • We can employ an air cooling method according to customer requirements to improve cooling efficiency.
  • We can add the screening function according to customer requirements to sort and process materials.

How does the bulk material vibrating spiral conveyor compare to a pneumatic conveyor?
The pneumatic conveyor uses high-velocity airflow to transport materials through an enclosed pipeline and is suitable for long-distance and enclosed conveying.

The bulk material vibrating spiral conveyor typically runs at low speed and therefore provides more residence time, and can reduce high-speed collision between some brittle pellets.

When do you choose a spiral conveyor over a traditional bucket elevator?
If a production line requires not only the vertical lifting of materials but also sufficient residence time for cooling and surface drying during conveying, a spiral conveyor is a preferable choice compared to a traditional bucket elevator. The spiral conveying path occupies less space and provides relatively stable material conveying. The spiral conveyor has easy-to-clean interiors and is suitable for plastic pellets and other bulk materials that require continuous lifting and processing at the same time.
