<p>In an apparatus for mitigating the drop impact of ores or the like using a buffer device (2) when they are transferred from a feeder or shooter S to a belt conveyor, a plurality of grooves extending in a belt conveying direction are formed on a slide support plate (3) of the belt (B) so as to reduce the contact area with the back of the belt and to reduce the heat of friction. An air stream fluidizing in the belt conveying direction is generated for cooling, and the gap between the shooter and a transfer apparatus is closed in such a manner that a skirt plate having a low friction resistance is supported so that it can be dropped under its own weight and the drop of the material to be conveyed outside the belt is prevented. Furthermore, on the return side of the belt, the belt is travelled while being curved at a predetermined angle of correction by inverted V-shaped rollers in order to prevent zigzag travel of the belt at the transfer surface and to prolong the life of the belt.</p> |
