Therefore, please confirm that you have obtained the following information:
1. The length, width and height of the transported object;
2. The weight of each conveying unit;
3. The bottom condition of the conveyed object;
4. Whether there are requirements for special working environment (such as humidity, high temperature, chemical influence, etc.);
5. The conveyor is driven by no power or motor.

To ensure smooth delivery of the goods, at least three pulleys must be in contact with the conveyor at any point in time. For soft bag packaging, trays should be added if necessary.

1, the length of the drum is selected:
For goods of different widths, the drum of suitable width should be selected. Under normal circumstances, “conveying material 50mm” is adopted.
2. Wall thickness and shaft diameter selection of the drum
According to the weight of the conveyed material, it is evenly distributed to the contact pulleys, and the required load of each drum is calculated to determine the wall thickness and the shaft diameter of the drum.
3, pulley material and surface treatment
Depending on the conveying environment, determine the material and surface treatment (carbon steel galvanized, stainless steel, black or rubber) used for the drum.
4, choose the installation method of the drum
According to the specific requirements of the overall conveyor, choose the installation method of the pulley: spring press-in type, inner-flange type, full flat type, through shaft pin hole type.

For the tapered pulley of the cornering machine, the width and taper of the rolling surface depend on the size of the cargo and the turning radius.
