Abstract (en)
[origin: EP0196105A2] Apparatus and method for containing and feeding particulate material tending to pack into a mass from an elongated hopper having opposed sloping walls converging downward and inward towards each other to terminal margins presenting between them an elongated laterally restricted outlet for directing material onto a conveyor below. Gates are provided to close the outlet for containing the material and to open the outlet to discharge it onto the conveyor belt. Baffles within the hopper are provided to divide the cargo at a level spaced above the outlet into several piles which merge above and below the outlet. In this way the material is channelled to the outlet so that lateral arches which may be formed in the material are prevented or broken up to assure feeding. Pressure may be relieved on some of the piles by flanges extending laterally of the baffles. The invention also includes the combination of gates equipped to break up longitudinal arches with baffles to prevent the formation of lateral arches.
