1. Choice of the length of the drum: For goods of different widths, the drum suitable for the width should be selected. Generally, the "conveyor + 50mm" should be adopted. 2. Selection of wall thickness and shaft diameter of the drum: According to the weight of the conveyor, the drum is evenly distributed to the contacting drum, and the required load of each drum is calculated, so as to determine the wall thickness and shaft diameter of the drum. 3. Drum material and surface treatment: According to the different conveying environment, the material and surface treatment (galvanized carbon steel, stainless steel, blackening or gluing) of the drum are determined. 4. Choose the installation mode of the drum: According to the specific requirements of the overall conveyor, choose the installation mode of the drum: spring pressing type, inner tooth shaft type, flat tenon type, through-shaft pinhole type, etc. For the conical drum of the bender, the width and taper of the roll surface depend on the size of the goods and the turning radius.
