Shaftless Spiral Conveyors / Horizontal Screw Conveyor Manufacturer
Screw Conveyor Introduction:
Shaft-less screw conveyor is a fairly recent development in screw conveyor design and is
growing in popularity because it is the perfect solution for many
bulk solids handling applications. The shaft-less screw conveyor is
the solution for conveying many difficult bulk solids. In fact, the
shaft-less conveyor was so successful in the Environmental
industry, that its use has been promoted in many other industries
such as chemical, food, and minerals processing.
Screw Conveyor Structure:
A shaft-less conveyor is designed to be supported by a liner that
conforms to the radius of the trough. The weight of the shaft-less
spiral is distributed over the full length of the spiral on the
liner. The drive is connected to one end of the spiral by means of
a flanged and bolted drive shaft and spiral end plate, while the
tail end of the spiral is not connected and is allowed to rotate
freely. If your process consists of bulk solids with high moisture
content, then the shaft-less screw conveyor is a perfect solution.
Our Advantages:
1. Strong anti-winding, no central axis interference. It has
obvious advantages for conveying the sticky material, easy winding
material.
2. Good environmental performance. It adopts fully enclosed spiral
surface, which can ensure that environmental hygiene and
transportation of materials from pollution, no leakage.
3. Large torque, low energy consumption. As the spiral without
shaft, the material is not easy to plug, the discharge port is not
blocked, which can be lower speed operation, smooth transmission,
reduce energy consumption. The torque can be 4000N / m.
4. Large conveying capacity. The capacity is 1.5 times as the
traditional shaft screw conveyor with the same diameter. Long
conveying distance and ultra-long distance transport materials. The
conveying length can reach 30 meters, which also can be adjusted
according to user needs and installed by multi-level series.
