The crushing of non-metallic materials is an important part of their processing and utilization. Therefore, dry crushing technology occupies an important position in the crushing operation of materials.
[0003] However, since people have corresponding demands for material particles of different particle sizes in production, it is necessary to repeatedly debug the crushing device to complete the crushing operation of the corresponding particle size, which prolongs the production time and thus reduces the production efficiency; or the crushed material is screened again through a screening device. Adding a process not only increases the equipment investment, but also reduces the overall production efficiency, which does not meet the production indicators of energy conservation, low consumption and emission reduction.

DETAILED DESCRIPTION
[0018] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0019] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.
[0020] The utility model will be described in detail below with reference to the accompanying drawings. Figure 1 As shown: the integrated crushing and screening crusher described in this embodiment includes a cylinder 1 with an inverted cone-shaped bottom, a feed hopper 2 arranged at the top of the cylinder 1, a material guide cylinder 3 arranged in the cylinder 1 and connected to the feed hopper 2, a screen plate 4 arranged in the middle of the cylinder 1, a rotating mechanism 5 inserted into the cylinder 1 from the center of the material guide cylinder 3, a dividing plate 6 and a cutter wheel 7 installed from top to bottom between the material guide cylinder 3 and the screen plate 4 through the rotating mechanism 5, and a classifying wheel 8 installed at the lower end of the screen plate 4 through the rotating mechanism 5, a material blocking cover 9 arranged on the outside of the dividing plate 6 and fixed on the material guide cylinder 3, a grinding circle 10 arranged on the inner wall of the cylinder 1 corresponding to the cutter wheel 7, a tangential air inlet 11 arranged on the side wall of the cylinder 1 below the screen plate 4, a coarse material port 12 arranged at the bottom of the cylinder 1, and a fine material port 13 arranged at the lower end of the classifying wheel 8 and extending out of the coarse material port 12.
[0021] The sieve plate 4 divides the interior of the cylinder 1 into an upper crushing chamber and a lower grading chamber. When in use, the rotating mechanism 5 is first turned on, and then the rotating mechanism 5 drives the dividing plate 6, the knife wheel 7 and the grading wheel 8 to rotate together, and then the material is put into the feed hopper 2, and the material falls onto the dividing plate 6 along the guide cylinder 3. Under the action of centrifugal force, the material is evenly thrown out, and the thrown material collides with the inner wall of the material blocking cover 9 and falls down. In this process, the material is partially collided and crushed, and the fallen material forms a vortex through the high-speed rotating knife wheel 7. The vortex material is crushed by mutual collision, the grinding and crushing of the grinding ring 10 and the material blocking cover 9, and the The cutting and crushing of the wheel 7 are carried out in three crushing modes at the same time. The materials that meet the particle size requirements fall into the grading chamber through the screening plate 4. At the same time, the tangential airflow blown in from the tangential air inlet 11 causes the fallen materials to rotate and fall. When the rotation radius becomes smaller and is subjected to the negative pressure of the grading wheel 8, the fine powder at the bottom of the grading chamber produces an upward vortex. The powder with qualified particle size passes through the grading wheel 8 and is discharged from the fine material port 13, and the coarse material with slightly larger particle size falls and is discharged from the coarse material port 12. The material crushing and screening are combined together, so that during crushing, not only the coarse material that meets the particle size requirements can be obtained, but also the powder can be screened out, which reduces the equipment of screening equipment, improves production efficiency, and is more widely used.
[0022] For ease of installation, as a preferred implementation of the above technical solution, the screening plate 4 is fixed between the cutter wheel 7 and the grading wheel 8 via a sealed bearing.
[0023] As a further improvement of the above technical solution, a plurality of evenly distributed grinding protrusions are provided inside and outside the side wall of the material blocking cover 9, thereby further enhancing the grinding and crushing efficiency.
[0024] In order to ensure the crushing efficiency and effect, as a preferred embodiment of the above technical solution, the grinding ring 10 is a gear ring structure with continuous inner teeth, such as Figure 2 shown.
[0025] As a further improvement of the above technical solution, a guide plate 14 with a downward arc is provided at the center of the lower end of the sieve plate 4, which can guide the rising powder airflow to prevent it from entering the grinding chamber from bottom to top.
[0026] For ease of use, as a further improvement of the above technical solution, a window for observing the internal crushing state is further provided on the side wall of the cylinder 1.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
