By using sealed conveying method.
1. Carrying products don't fall off or spill out, not causing any pollution.
2. Using pipe conveyor belts in the return process, fallen objects do not attach to the inner surface of the belt, and not causing any damage to the belt surface.
3. Prevent other substances from entering, assuring purity of products.
1. The abrasion between the products and inner belt surface increases when conveyor belts are in pipes, this enables greater transporting degree than other commonly used belts.
2. Traditional conveyor belts only allows conveying at a straight line which needs extra space for curves. Tube form conveyor belts offers simplified transport system which help saves space and cost.
