Unitfine Tube Chain Conveyor

Tube chain conveyor, also called drag conveyor ,is continuous conveying equipment conveying powder, granular and other small lump bulk materials, which can horizontal, inclined and vertical combination delivery.



In a sealed pipe, the chain is driven by a belt of animal material along the pipeline. When the horizontal transportation, the material particles are in the direction of movement of the chain in the direction of the thrust. When the friction material layer is greater than the external friction material and the pipe wall, the material will move with the chain sheet, forming the stability of material flow; when the vertical transportation, tube material particles by chain upward thrust, because the lower feeding to prevent the decline in the upper part of the material, resulting in a transverse lateral force, so it enhances the internal friction of the material, when the friction between the materials are greater than the material and pipe wall friction and material weight, material with chain plate conveyor upward, forming continuous material flow. Please see below video to know it better:

Fine Chemicals: pigments, dyes, paints, carbon black, titanium dioxide, iron oxide,
ceramic powder, GCC, light calcium, bentonite, zeolite, kaolin, silica
powder, activated carbon, etc.
Pesticide Mineral: urea, ammonium chloride, ammonium bicarbonate, baking soda,
solid pesticides, tungsten powder, pesticide chemicals, copper
powder, coal, phosphate rock, alumina powder.
Building material: cement, clay, sand, quartz sand, clay powder, silica, limestone,
dolomite, wood flour, glass fibers, silica, talc, etc.
Food industry: flour, starch, grain, milk, and food additives.

drag conveyor application details1

1. Volumetric delivery device, enabling materials delivery and metering . Easy to
implement centralized control, increased automation, to meet the requirements
of modern enterprise for environmental protection.
2. Compact structure, small footprint, it can change the transport direction of the
3. Material being conveyed between inlet and outlet flange is in the closed state.
There is no need to set dust remover at the outlet. When transporting materials
can fill gas. Which ensure no dust leak into the environment during transportation.
4.Material transport smoothly along the tube, virtually no internal movement, so
Less material damage, slow corners transport make less material particles
    generated debris.
5. Depending on the feeding case, the inlet distance can be more than 10 meters .
6. sprockets have optimized shoulder, design optimization, the use of hardened
chains having a minimum wear.
7. Special delivery tray, has a very low friction coefficient and stable transmission
8. May discharge at multiple points in circuit;no special airlocks are required.
