What are the classifications of conveying rollers?
The conveying roller is a kind of equipment which plays the role of bearing and pushing materials on the conveying line. According to different application scenarios and structural characteristics, the conveying rollers can be divided into the following types:

1. Classification by material:

-Metal conveying roller: mainly used for conveying heavy objects with high strength and wear resistance.

-Plastic conveying roller: suitable for conveying materials with high friction coefficient, such as food and medicine.

-Rubber conveying roller: It has good wear resistance and impact resistance, and is suitable for conveying worn materials.

2. According to the structure classification:

-Single-row conveying roller: mainly used for linear conveying occasions, with simple structure and stable operation.

-Double-row conveying rollers: used for complex conveying systems, such as slope and curve conveying.

-Multi-row conveying rollers: suitable for long-distance and high-efficiency conveying lines.

3. Classification according to driving mode:

-Manual conveying roller: materials are conveyed by manual driving device, which is suitable for short-distance transportation.

-Electric conveying roller: driven by motor, which realizes automatic operation and is suitable for long-distance and high-efficiency conveying lines.

4. Classification by mode of transportation:

-Parallel conveying roller: mainly used for parallel conveying lines, such as flat conveyor.

-Inclined conveying roller: used for inclined conveying occasions, such as slope conveyor.

-Spiral conveying roller: It has a spiral shape and can be used for vertical or spiral conveying.

5. Classification by function:

-General conveying roller: only used for carrying and pushing materials.

-Weighted conveying roller: On the basis of ordinary conveying roller, the bearing capacity is increased, which is suitable for conveying heavier materials.

-Heating or cooling conveyor roller: used for heating or cooling materials, such as food and chemical industries.

These classifications are not absolute. In practical application, the types of conveying rollers can be combined and customized according to actual needs. Understanding these classifications is helpful to choose the appropriate conveying roller for different occasions.
