Maximum particle size of material to be transported by belt conveyor

What is the maximum particle size of the material that can be transported by a belt conveyor? This depends on the choice of the belt width and the angle of inclination of the belt.
Belt conveyor is generally used to transport bulk materials, granularity from fine powder to lump materials, generally speaking, for example, the commonly used plane conveyor belt, the bandwidth of 500mm, the size of the material can not exceed 100mm; bandwidth of 650mm, the size of the material does not exceed 120mm; bandwidth of 800, the granularity of the material 200mm; bandwidth of 1000, the granularity of the material 300mm; bandwidth of 1200mm and larger bandwidth conveyor belt, the maximum particle size of the material transported by the belt conveyor does not exceed 350mm. 1200mm and larger bandwidth conveyor belt, belt conveyor transportation material maximum particle size does not exceed 350mm.

The above are the bandwidth of materials that can be transported in horizontal conveying.
If the belt conveyor is inclined, then the granularity of the material to be transported should be reduced accordingly. As mentioned at the beginning, the angle of inclination also affects the size of the granularity of the material that can be transported by the belt conveyor.
When there are different kinds of conveyor belts, such as large inclination belt conveyor, using skirt conveyor belt, then its effective bandwidth corresponds to the reduction of the maximum particle size of the transportable material does not exceed 100mm.
