PURPOSE:To prevent the reduction of driving horsepower and the generation of a fiber bowl in a belt conveyer, by which a ferromagnetic material mixed in fiber reinforced concrete is transferred diagonally upward, by constituting said belt conveyer such that spaces are provided in both sides of a non-magnetic belt and magnetic poles are arranged. CONSTITUTION:If a fiber 50 is continuously supplied from a supply port 30 onto a belt 26, a magnetic path 52 formed such as electromagnetic coil 40 - yoke 38 - magnetic pole 34 - fiber 50 - magnetic pole 36 is generated, then the fiber 50 is magnetized. In consequence, a central part of the belt 26 except on the magnetic poles 34, 36 also the fiber 50 between the magnetic poles 34, 36 are attracted to each other while in cooperation with tangling quality, and the fiber is not dropped but carried upward. By this constitution, the fiber is carried up together with a material contained except the belt 26, and the generation of a fiber bowl can be prevented with small horsepower. |
