DJA wave-shape apron belt conveyor has the advantages of simple construction, reliable operation, convenient maintenance, large inclination conveying, large conveying capacity, small floor area and long service life, being favorable to overall design and low overall cost, etc. Therefore, it is an ideal equipment for large inclination conveying. It is widely used in such sectors as of coal, metallurgy, building material, grains, chemical engineering, electric power, etc., and it is used to convey various bulk materials with bulk density of 0.5~2.5t/m3 at the ambient temperature of -20°C~+40°C. It adopts the conveyor belt made of special materials, which can convey special materials such as high temperature resistant material, acid and alkali resistant material, oil resistant material, etc.
