Wherein, referring to fig. 1 and 3, the upper grinding disc 10 includes an upper disc body 101, an upper rotating rod 9 is fixedly installed on the top of the upper disc body 101 near the analyzer 5, a secondary material inlet pipe 102 is installed on one side of the upper disc body 101 near the upper rotating rod 9, the upper end and the lower end of the secondary material inlet pipe 102 are open, the bottom end of the secondary material inlet pipe 102 is communicated with a collecting pipe 103, the bottom of the collecting pipe 103 is communicated with the outside of the upper disc body 101, the bottom of the collecting pipe 103 faces the top of the middle chamber 72, so that the secondary material from the secondary material inlet pipe 102 is finally collected in the collecting pipe 103 and then falls into the middle chamber 72 from the collecting pipe 103, the upper surface of the upper disc body 101 is an inwardly concave circular table, since the upper disc body 101 also rotates under the action of the upper rotating rod 9, the secondary material falling from the upper surface of the upper disc body 101 at the conical valve 8 is thrown out without secondary grinding, and the upper surface of the upper disc body 101 is inwardly concave, when the centrifugal force drives the secondary materials to slide to the upward slope of the circular truncated cone, the secondary materials finally slide downwards under the action of gravity, and the grinding times of the secondary materials are reduced.

The bottom of the upper disc body 101 is provided with a groove similar to the groove 73, and the groove is used for increasing the friction force between the surface of the upper disc body 101 and the secondary material.

The included angles of 5-10 degrees are formed between the upper surfaces of the lower disc body 71 and the channel 73 and between the lower surface of the upper disc body 101 and the horizontal plane of the upper top of the middle cavity 72, and the lower disc body 71 and the channel 73 are obliquely arranged so that the ground secondary materials can be thrown outwards under the action of gravity and centrifugal force after being ground to the required fineness, and discharge of the ground materials is accelerated.

Wherein, the direction of rotation of analysis machine 5 is opposite with grinder 4's rotatory direction, when grinder 4, the turning to of analysis machine 5 is opposite, lower mill 7 this moment, the direction of rotation of upper mill 10 is opposite, turn to opposite lower mill 7, upper mill 10 and grind the secondary material, can reduce the emergence of the condition of skidding effectively, grind the secondary material simultaneously from two directions simultaneously, make the grinding power that the material received bigger, make the grinding effect of secondary material obtain improving, in addition because the pivoted speed of analysis machine 5, grinder 4 is different, utilize the differential to grind the secondary material.

Wherein, the upper end of lower rotor 6 and the 9 bottoms of last rotor are equipped with the screw thread, lower mill 7, be equipped with on the runner 10 with lower rotor 6, the thread groove that runner 9 matches, the direction of screwing up of runner 9 screw thread is opposite with the direction of rotation of analysis machine 5, the direction of screwing up of runner 6 upper thread is opposite with grinder 4's direction of rotation, the condition of droing avoids appearing, simultaneously the screw thread setting can conveniently adjust lower mill 7, the distance between the runner 10, lower mill 7, the distance between the runner 10 mainly adjusts according to the required material fineness, the screw thread setting also can make things convenient for mill 7 under the later stage, runner 10 wearing and tearing are changed.

In summary, as can be seen from fig. 1 and 3, the normal flow direction of the airflow is that the airflow enters from the air inlet 3 to drive the material ground by the grinding device 4 to move up to the analyzer 5, the analyzer 5 analyzes the material, the material in accordance with the requirement is discharged, and the secondary material not in accordance with the requirement falls down from the middle of the main machine housing 1 through the cone valve 8, and then is received by the upper surface of the upper disc body 101, and the received secondary material falls down under the action of gravity, and falls into the channel 73 through the secondary material inlet pipe 102 and the collecting pipe 103, and starts to move to an area far away from the center of the circle under the action of the extrusion force of the secondary material and the rotating centrifugal force of the lower grinding disc 7, during which, because the lower grinding disc 7 and the upper grinding disc 10 rotate reversely and at a differential speed at the same time, the secondary material is ground reversely, and after being ground to a suitable fineness, because the size of the ground secondary material and the lower grinding disc 7, The distance between the upper millstone 10 is close, so that the friction force between the material and the lower millstone 7 and between the material and the upper millstone 10 is reduced, and the friction force is overcome by centrifugal force, so that the material meeting the requirements is thrown into the main machine shell 1, is driven by the airflow flowing upwards outside the lower millstone 7, flows into the analyzer 5 again, and is screened and detected by the analyzer 5.

The using method of the invention is as follows:

firstly, before the operation, the distance between the lower grinding disc 7 and the upper grinding disc 10 is adjusted to a proper angle, so that the distance between the lower grinding disc 7 and the upper grinding disc 10 is the same as the required size of the sand, after the whole Raymond mill starts to operate, the grinding device 4 grinds the sand from the feeding device, the material after the first grinding flows upwards by utilizing the air flow entering from the air inlet 3, then the material is analyzed in the analyzer 5, the analyzer 5 analyzes the material, the material which meets the requirement is discharged, the secondary material which does not meet the requirement falls downwards from the middle part of the main machine shell 1 through the cone valve 8 and is then caught by the upper surface of the upper disc body 101, the caught secondary material falls downwards under the action of gravity, and falls into the channel 73 through the secondary material inlet pipe 102 and the collecting pipe 103 under the action of the centrifugal force of the extrusion force of the secondary material and the rotation of the lower grinding disc 7, begin to the regional motion of keeping away from the centre of a circle, in this process, because lower mill 7, it is reverse simultaneously to go up mill 10, the differential is rotatory, therefore the secondary material is by reverse grinding, grind to suitable fineness after, because the secondary material size after grinding is close with lower mill 7, the distance between the mill 10, can make material and lower mill 7, the frictional force between the mill 10 reduces, centrifugal force overcomes frictional force, make the material that meets the requirements get rid of in host computer casing 1, be driven by the air current of mill 7 outside upflow down, flow again in the analysis machine 5, by the screening of analysis machine 5, detect, the discharge that meets the requirements, the secondary material that does not meet the requirements gets back to lower mill 7 once more, grind between the mill 10, repeat this process.
