1, the length of the roller:
The goods should be suitable for different drum width width, typically using "delivery +50mm".
2, the wall thickness of the roller and the shaft diameter choice:
According to the weight of the conveying material to the contact roller, the load bearing capacity of each roller is calculated.
3, roller material and surface treatment:
According to different transporting environment, determine the drum the materials and surface treatment (galvanized carbon steel, stainless steel, black or plastic bag).
4, select the roller installation method:
According to the specific requirements of the overall conveyor, roller installation: spring is pressed into the type, inner tooth shaft type, the oblate tenon type, a pin hole type.
For the tapered roller of a curved machine, the rolling width and taper of the taper roller are determined by the size of the goods and the turning radius.
