The method is further optimized as follows: the throwing holes are arranged in a plurality of numbers, and the throwing holes are uniformly distributed around the inner cylinder.

Adopt above-mentioned structure for the dust and sand mixture can be thrown away from a plurality of throwing away holes.

The method is further optimized as follows: the top of the V-shaped powder concentrator is provided with a dust and sand mixture inlet, the upper part of the feeding channel is connected with the cylinder, and the lower end of the feeding channel is communicated with the dust and sand mixture inlet.

By adopting the structure, the connectivity among the cylinder body, the feeding channel and the V-shaped powder concentrator is improved, and under the transmission of the feeding channel, the dust and sand mixture thrown out by the inner cylinder can enter the V-shaped powder concentrator.

The method is further optimized as follows: the throwing hole and the through hole are both rectangular, and the length and the width of the through hole are both larger than those of the throwing hole.

By adopting the structure, the throwing-out obstruction of the dust-sand mixture is reduced, so that the dust-sand mixture thrown out through the throwing-out hole can quickly enter the feeding channel through the through hole.

To sum up, the utility model discloses following beneficial effect has: in the dust and sand mixture falls into the inner tube through the feeder hopper, when the motor started, the inner tube will take place rotatoryly in the barrel, and the inner tube rotates the in-process, and the dust and sand mixture in the inner tube will follow the inner tube and rotate together, and under the effect of centrifugal force, the dust and sand mixture will get rid of into feedstock channel through getting rid of the hole and through-hole to enter into V type selection powder machine through dust and sand mixture import. Because inner tube outer wall and barrel inner wall contact, consequently only get rid of when going out the hole just to the through-hole, the dirt sand mixture in the inner tube just can throw out through throwing away the hole to enter into feedstock channel, can effectively control dirt sand mixture unloading speed. Prevent that the unloading of dust sand mixture is too fast or slow, prevent that machine-made sand gumming is uneven and V type selection powder machine from blockking up, can effectively improve machine-made sand gumming efficiency.
