How does the conveyor belt affect the climate?
The ocean circulation conveyor belt helps balance climate. As part of the ocean conveyor belt, warm water from the tropical Atlantic moves poleward near the surface where it gives up some of its heat to the atmosphere. This process partially moderates the cold temperatures at higher latitudes.
Why is conveyor belt made rough?
The roughness increases the hold of the belt on the objects kept on it by increasing the friction. This prevents the objects (luggage etc.) from slipping or sliding as the belt moves.
How do you track a belt on a conveyor?
The basic rule which must be kept in mind when tracking a conveyor belt is simple, “THE BELT MOVES TOWARD THAT END OF THE ROLL/IDLER IT CONTACTS FIRST.” You can demonstrate this for yourself by laying a small dowel rod or a round pencil on a flat surface in a skewed orientation.
How do vibrating conveyors work?
