Product introduction:
KRD tube chain conveyor is the special equipments to continuously convey fine powder and granule bulk materials. The types of Tube chain conveyors can be catogarized as horizontal flat, horizontal upright and vertical upright.
For horizontal conveyors, the chains and disks generate horizontal thrust to push the materials. When the internal friction of material is greater than the external friction of material on tube wall, the material will move with the disks and form a stable flow.

For vertical conveyor, the chains and disks generate up 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 dead weight, the product will move upwards with the disks and form a continuous flow.

Delivery capacity: 0.4-300m3/h
Delivery Distance: 60-80m (horizontal); 40-50m (vertical)
Power: 0.2-15KW

Advantages of tube chain conveyor system:
1. Positive-displacement conveying device can realize conveying and computing powder, easy centralized control, improving degree of automation and satisfying environmental protection requirements from modern enterprise.
2. Compact conformation, little space usage, tridimensional conveying direction available.
3. Flanges between inlet and outlet are airtight, then there is no need to install filter. There is no dust spread into environment.
4. Powder is conveyed smoothly along the lines with little internal movement. Therefore, there is little breakage against materials. Slow curve conveying make little material granule into chipping.
5. According to different feeding conditions, distance between inlets can exceed 10m.
6. Chain wheel has been under hardening with minimum abrasion
7. Special transfer dish with extremely low coefficient friction and stable delivery capacity.
8. All our tube chain conveyors use our own computer program for different parts such as conveying line and curve parts to maintain necessary static friction and pull-up and providing precise data to reach to low noise and little abrasion.
