Including Cable & Disc and Chain & Disc Types


Tube and chain conveying nz
Our tube and chain conveyors come in a wide range of sizes to choose from. We are bound to have a conveyor that meets your product transportation needs.


Tube and chain conveying nz
Our Engineers can innovate alternative design arrangements to convey bulk materials within tight space confinements.


Tube and chain conveyors, and tube cable disc conveyors are designed to continuously convey fine powder granules and bulk materials. They can be installed as horizontal, horizontal and vertical, and standalone  vertical arrangement.

For horizontal/flat and horizontal/upright, the cable or chains and discs generate horizontal thrust to push the materials. When the internal friction of material is greater than the external friction of material on the tube wall, the material will move with the discs and form a stable flow.

For vertical/upright, the chains and discs generate up vertical thrust. The under-feeding pattern prevents the product falling and generates lateral pressure that will reinforce the internal friction. When the internal friction is greater than the external friction and the product’s dead weight, the product will move upwards with the discs and form a continuous flow.

Delivery capacity:
 0.4-300m3/hr according to model and size     
Maximum delivery distance:
 80m (horizontal); 60m vertical
 0.2-30kW according to model and size

Tube and Chain & Cable Conveyor System’s Features:

    1.    Flexible: 3D with the tube and chain conveyor

    2.    Sealed pattern: dust-tight

    3.    Low energy consumption: low costs

    4.    No dead areas

    5.    No metal on metal friction

    6.    Low maintenance cost

    7.    Long lifetime operation

    8.    Explosion and pressure shock resistant design

    9.    Possible to re-start in filled state

    10.  Minimal grain or material degradation

Advantages of Tube Type Chain Conveyor

1.    Positive displacement conveying suited to easy centralized control, improving degree of automation and satisfying environmental protection for industrial applications.

2.    Compact design requiring limited space, tri-dimensional conveying direction available.

3.    Flanges between inlet and outlet are airtight, and there is no need to install a filter. No dust emission into the environment.

4.    Material is conveyed smoothly along the lines with little internal movement. Therefore, there is little breakage of material. Slow curve conveying ensures minimal product degradation.

5.    According to different feeding conditions, distance between inlets can exceed 10m.

6.    The hardened chain wheel causes minimum abrasion on operation chain components.

7.    Special transfer dish with extremely low coefficient friction and stable delivering capacity.

8.    All our tube and chain conveyors use our own computer program to design parts including conveying line and curve parts to maintain necessary static friction and take up and provide precise data to ensure low noise and little abrasion.
