To select the appropriate chain plate line according to the demand, the following factors need to be considered:

1. Material properties: Different materials have different requirements for conveying equipment, such as granular, powdered, liquid, etc., need to consider the conveying capacity of the chain plate line, wear resistance, sealing, etc.

2. Conveying capacity: Select the size and model of the chain plate line according to the output of the production line and the amount of material conveying to ensure that the production needs can be met.

3. Process requirements: According to the special requirements in the production process, select the chain plate line with the corresponding functions, such as ultra-high temperature, dustproof, corrosion resistance and other special process requirements.

4. Environmental requirements: According to the characteristics of the working environment, choose the chain plate line with high temperature resistance, dust proof, explosion proof, corrosion resistance and other characteristics.

5. Layout restrictions: Consider the layout restrictions of the production line, select the appropriate chain plate line type, such as straight, curved, back transformation, etc.

6. Maintenance: Choose the chain plate line with simple structure and easy maintenance to reduce the difficulty and cost of daily maintenance work.

7. Economic benefits: comprehensive consideration of equipment cost, service life, energy consumption and other factors, the selection of cost-effective chain plate line, in order to achieve the maximum economic benefits.

Therefore, when selecting the suitable chain plate line, the above factors need to be considered comprehensively to ensure that the appropriate equipment is selected to meet the production needs.
