Conveyor Chain Exclusive for Specific Conveyance
Conveyor Chain with Attachments for Conveying Bulk Materials
We manufacture continuous flow conveyors and dust conveyors using the above chains with blades as standardequipment. Consult us for further details.
Continuous Flow Conveyor Chain and Chain for Dust Conveyor
Standard Conveyor Chains with blades → Continuous Flow Conveyor Chain
or Chain for Dust Conveyor
Block Chains with blades → Block Chain for Dust Conveyor
Chain with special cast steel blades → TA Type Drag Chain
The previous section describes that by combining with various attachments, the DK Conveyor Chains can be used foralmost all general applications. This section describes the DK Specialty Conveyor Chains developed based on theStandard Conveyor Chain. Specialty Conveyor Chains offer improved form, size series and material advantages that suitrespective applications. They can be classified into three types: Specialized Application Conveyor Chain, WaterTreatment Conveyor Chain, and 3D Bending Conveyor Chain.
As shown in the photo, a chain with blades is operated in a powder to cause the powder to flow in the same directionas the feeding direction of the chain. This is called a Continuous Flow Conveyor Chain. The same type of chain is alsoused in a similar way for discharging the dust generated by various dust collectors. We manufacture 25 types ofStandard Conveyor Chains with blades, two types of Block Chains with blades (P.284), respectively suitable for thevarious properties of dusts and powders, and five chains with special cast steel blades for conveying powders likely tocause wear. The respective chains are designated as follows:

For the conveyance of bulk materialssuch as grain like wheat and powderlike cement.
For the conveyance of adhesive bulkmaterial.
For the conveyance of bulk materiallike cement with higher feedingefficiency than Attachment L.

Shapes and Indications of Attachments
Indication1. An attachment is indicated by a hyphen added after
the symbol of tensile strength grade. However, in thecase of a strong type conveyor chain, an attachmentis indicated by adding a hyphen after the roller type.
Example) DK19152S-K-L
DK75H200M-L
2. In the case of an inclined attachment, "K" is addedbefore the attachment symbol.
Example) DK19152S-A-KLDK75H200M-KUL
3. When an attachment has a steel sheet or rib, etc. asan accessory, "1" is added at the end.
Example) DK19152S-E-B1DK75H200M-KB1
