Pipe Conveyors

Pipe conveyor belt is similar to conventional conveyor belt at material receiving and discharge area. In intermediate section, belt gradually takes on a pipe formation with the help of special idlers. This type of belts is widely used in mining, coal, cement, metallurgical and other industries.

The pipe conveyor design comprises a loading or tail end section, intermediate section, head or discharge section and drive assembly.

On the carrying side in tail end, skirts are provided to prevent spillage of the loaded material. During belt moving in the direction of travel, the belt is troughed via transition idlers. From the loading point, the conveyor belt is further gradually to the full pipe form. Adjustable troughing idlers along the section guide the belt into the formation of the pipe shape. The overlap in belt is at the top of the pipe formation and finger rolls are used to guide the belt in pipe formation.

Proper alignment of tail pulley, idlers and the centralized loading of the conveyor are all important to correct formation of pipe and positioning of belt overlap. On the return side in tail end, the tubular form of belt is gradually opened from the point where the belt exits at the last idler support panel to the tail pulley. An adjustable return belt scrapper is provided prior to the tail pulley to remove any residual material from the belt before it passes through the tail pulley.
