In an autogenous mill or a semi-autogenous mill, materials generally have two motion forms of throwing and dropping, and the grinding effect also has two types of impact crushing and grinding and stripping crushing. After being thrown by the lining plate lifting strip, the materials or grinding media (steel balls) are smashed to the toe materials or the lining plate of the autogenous mill or the semi-autogenous mill under the action of gravity to cause the crushing of the materials, and the materials or the grinding media which do the leakage movement have the grinding and stripping function mutually, so that the materials are crushed through the grinding and stripping function. Generally, the material crushing mode inside the autogenous mill or the semi-autogenous mill is mainly impact crushing.

As shown in fig. 10, the first air supply region 8 is arranged at the upper position on the left side of the inner cylinder 5, and the position is a position where large-particle materials slide down. When the inner cylinder 5 of the semi-autogenous mill rotates in the positive direction to crush large-particle materials, high-pressure air is supplied into the first air supply area 8, and the high-pressure air can enter the first channel 215 and the second channel 216 through the air vents on the inner cylinder 5 at the first air supply area 8 and then is blown out from the air vents 307 on the first stress surface 301, the second stress surface 302 and the second inclined surface 402. Because the first air supply area 8 is located at the position where large-particle materials slide down, the blown high-pressure air has at least the following functions: on one hand, the downward sliding large-particle materials can be impacted, the crushing effect is achieved, and the crushing effect of the large-particle materials is improved; on the other hand, the impact on the gliding large-particle materials can loosen the large-particle materials, the falling area of the large-particle materials after falling can be enlarged, the total contact area of the large-particle materials with the first stress surface 301, the second stress surface 302, the third stress surface 303 and the second inclined surface 402 is increased, and the large-particle crushing effect is further improved; moreover, after the impact of high-pressure air on the gliding large-particle materials changes and loosens the large-particle materials, fine particles (including the materials meeting the crushing particle size) mixed in the large-particle materials can be lifted and discharged and collected through an air exhaust system, so that the materials meeting the crushing particle size can be timely discharged and collected, the materials meeting the crushing particle size are prevented from being excessively crushed, and after the fine-particle materials meeting the crushing particle size are timely separated, the continuous crushing of the large-particle materials not meeting the crushing particle size is facilitated; especially, the impact energy of high pressure wind to the gliding large granule material makes the large granule material accelerate downstream, for only leaning on gravity whereabouts, the large granule material can be with higher speed downstream and assault on first stress surface 301, second stress surface 302, third stress surface 303 and the second inclined plane 402 of below, and then improves the crushing effect of large granule material greatly, promotes the crushing efficiency of large granule material, and the effect is showing especially.

As shown in fig. 11, the second air supply area 9 is provided at a position in the middle of the right side of the inner cylinder 5, where the small granular materials slide down to the midway. After the large particle materials are crushed into small particle materials, the inner cylinder 5 of the semi-autogenous mill rotates reversely to crush the small particle materials, and then high-pressure air is supplied into the second air supply area 9, and the high-pressure air can enter the first channel 215 and the second channel 216 through the air vents on the inner cylinder 5 at the second air supply area 9 and then is blown out from the first stress surface 301, the second stress surface 302 and the air vents 307 on the second inclined surface 402. Because the second air supply area 9 is located at a position where the small particle materials slide down to midway, when the small particle materials fall from the sliding position to the midway position, the small particle materials which initially fall and are dispersed can be further dispersed under the action of blown high-pressure air, so that the dispersed area is increased, the areas of the small particle materials falling to the first stress surface 301, the second stress surface 302, the third stress surface 303 and the second inclined surface 402 are increased, the effective area of the small particle materials which are further crushed is increased, and the crushing effect is further improved; on the other hand, under the effect of high pressure blowing, the material that accords with broken granularity in the further tiny particle material that scatters is raised the back, can be discharged and collect by exhaust system, and then accord with broken granularity's material separation and collection in the tiny particle material, not only can prevent that the tiny particle material that accords with broken granularity is excessively smashed, can also be in the material that accords with broken granularity by in time after the separation, improve the crushing effect of surplus tiny particle material, and then promote the crushing efficiency of tiny particle material, the effect is showing especially.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
