When deciding on the chain type, we first determine the transport method after understanding the properties of the transported items, and then select the most economical chain conveyor type for that purpose.

Conveyor chains can be used in the three basic formats shown in the table above, as well as other formats. Refer to the previous page to determine the chain format that best suits your application.

Points to note when deciding on chain format

・The loading method is used to reduce the running resistance when transporting goods. By using the loading method, energy savings can be achieved. Bearing rollers and coil transfers are ideal. - If the transported material is powder or liquid, which accelerates chain wear, make sure the structure does not allow it to come into contact with the chain. - When transporting bulk item, to prevent scattering of the transported items, a sealed conveyor such as a flow conveyor is used. - When transporting highly corrosive materials or using conveyor chain in a corrosive atmosphere, select the appropriate chain specifications. (See Corrosion Resistance to Various Solvents.)

Please refer to "Roller Types" in Large size conveyor chain Structure section.

5.1 Horizontal transport

1) On the outer side of the drive sprocket Catenary (sagging) How to make

2) Method without supporting return-way

It has a short conveyor length and can be used at low speeds.

The tension caused by the mass of the chain on return-way can cause vibrations, which can prevent smooth transport.

3) return-way is supported by a guide or roller.

The chain comes into contact with the guides and rollers and articulate, which can accelerate wear and make it more susceptible to scratches.

Chain vibrations can also have a negative effect, and if conveyor length is long, they may be split and absorbed by the catenary.

4) return-way is entirely supported by the guide.

This method supports the entire return-way with rails and attaches a take-up to the driven sprocket to absorb the chain slack.It can also be used when there is reverse rotation.

However, since the catenary is not located at the point where it exits the drive sprocket, the chain must be periodically adjusted with a take-up to remove any tension.

Note: Please be careful not to overtighten the take-up as this can cause the chain to wear out faster.

5) Example where return-way is upward

5.2 Vertical conveyance

5.3 Inclined transport

5.4 When the axis is vertical

When the shaft is vertical, such as for horizontal circulation, attach guide rollers to the chain to ensure smooth movement of the chain.

The recommended chain specifications are listed below for reference based on the chain conveyor types and chain specifications used for transporting bulk item bulk items.

Depending on the conveyed item, the situation and properties may differ from those shown in Table 1 even if the name is the same, so please take past performance into consideration and give careful consideration before deciding on the conveyor type and chain specifications.

Table 1. Conveyed items and chain specifications

• 1. The abrasion resistance of conveyed objects decreases in the order of large → medium → small.
• 2. Corrosivity is indicated as strong acidity, acidic, neutral, alkaline, or strong alkaline.
• 3. When using the beauty specifications, please refer to the beauty specifications.
