DRAG CHAIN CONVEYOR

OVERVIEW

    
Drag Chain conveyor is a material handling equipment to convey the material for medium amd shorter distance by dragging the material with the help of chain link assembly. The constructional feature comprises of conveyor in three segments. They are drive end casing segment, Tension end casing segment and intermediate casing segment.

The drive end segment consist of drive sprocket mounted on shaft and shaft coupled with drive arangement though transmission chain arangement or coupling. Similarly tension end casing segment consist of trailing wheel mounted on shaft having a tension end acccessories of screw or spring take-up arrangement to adjust the chain tension.

Intermediate casing segement shall house the chain and wear strip. Conveyor shall be mounted on structural support either fixed or sliding considering the operating temperature. At elevated temperature the design of drive end casing changes in order to compensate the thermal expansion of chain link.
  
     

TECHNICAL DETAILS

    
1. Standard chain conveyors are made out of carbon steel.
2. Used for carrying abrasive, moderately abrasive and non-abrasive items.
3. The speed of chain link depends upon material character and restricted to 0.3 m/sec.
4.Wear liner shall we provided according to material characteristic of MOC sail hard/Hardox 400.
5. Chain shall be selected as per DIN standard 20MnCr5 OR equivalent IS 4432 standard.
6. Shaft selection shall be done according to BS 970.
7. Sprocket shall be split type construction.
8. According to machine width of conveyor will have single strand or double strand.

    SALIENT FEATURES

    		    
    1. Low power consumpstion as compared to other conveying capital equipments.

    2. Wide range of materials can be handled.

    3. Design for dust and vapor-tight requirements hence eco-friendly.

    4. Multiple inlet and outlet points will allow the equipment have intake and discharge flexibility.

    5. Being a tailor made design, capacity can be designed as per customer requirment. At present installed upto 325TPH.

    6. Length can be varied as per customer requirment from the range of from 3mtrs to 160mtrs. However depend upon the
         capacity of conveyor.

    7. Conveyor can be inclined upto maximum of 12 degree.
