The housing 3 is provided with a feed inlet 301, the feed inlet 301 is used for feeding the outer roller 4, and the feed inlet 301 can be arranged at the top of the housing 3 or at the side of the housing 3. Because the starting end in concentrate sorting district has been injectd to the position of outer cylinder 4 cooperation feed inlet 301 feeding, for the concentrate sorting district of increase outer cylinder 4, improve ore dressing efficiency, the preferred setting of feed inlet 301 is at casing 3 top. In order to reduce the impact wear of the raw ore on the outer drum 4, it is preferable that the feeding port 301 extends into the casing 3, the feeding direction of the feeding port 301 is inclined downward with respect to the horizontal plane to avoid vertical impact, and the inclined feeding causes the raw ore to have an initial velocity following the movement of the outer drum 4 when the raw ore falls down to the working surface of the outer drum 4.
