With the continuous advancement of science and technology and the continuous optimization of technology, the production efficiency and product quality of cement are also constantly improving. In summary, the production of cement involves multiple complex process links and key equipment, each of which has an important impact on the quality and production efficiency of the final product. In the cement production process, particle crushing and impurity removal are important links to ensure the quality of cement. Particle crushing and impurity removal in cement production are key links to ensure the quality of cement.

One side of the outer wall of the two driving rods 461 is fixedly connected with a grinding roller 462, and the other side of the outer wall of the two driving rods 461 is fixedly connected with a rotating motor 464. The outer walls of the two rotating motors 464 are A set of motor plates 465 are fixedly installed, and one side of the outer wall of the two sets of motor plates 465 is fixedly connected to one side of the outer wall of each angle compensator 46. A top mounting frame 47 is fixedly connected to the top center of the bottom frame 41. A movable groove 471 is opened between the bottom frame 41 and the top mounting frame 47. A linkage rod 472 is driven to rotate on the inner wall of the movable groove 471. A driving motor B473 is fixedly connected to the bottom of the linkage rod 472. A fixed plate 474 is fixedly installed on the outer wall of the driving motor B473. The top of the fixed plate 474 is fixedly connected to the top of the inner wall of the bottom frame 41. The top of the linkage rod 472 is fixedly connected to the grinding disc 4 8.

[0024] In this embodiment, after the crushed cement material enters the interior of the grinding and removing mechanism 4, first, the fixing plate 474 at the bottom can fix the driving motor B473 at the bottom of the base frame 41 and keep the driving motor B473 in a fixed state. When the driving motor B473 is powered on, its output end can drive the linkage rod 472 to rotate, and the linkage rod 472 can be used as a medium to keep the grinding disc 48 rotating. After the cement material falls on the top of the grinding disc 48, the two rotating motors 464 at the other end are powered on to respectively drive the driving rod 461 and the grinding roller 462 on one side of the outer wall to rotate. After the grinding roller 462 contacts the cement block on the top of the grinding disc 48, the particles are squeezed by the two grinding rollers 462 and then crushed between particles.

Embodiment 2

[0025] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5As shown, the crushing mechanism 2 includes a placing frame 21, the top of the mounting body bottom plate 1 is fixedly connected to the bottom of the placing frame 21, an operating frame 22 is fixedly inserted into the inner surface wall of the placing frame 21, two groups of driving grooves 221 are preset inside the operating frame 22, a funnel plate 23 is fixedly connected to the top of the operating frame 22, an output port 24 is opened at the bottom of the operating frame 22, bearing seats 25 are fixedly inserted into the inner surface walls of the two groups of driving grooves 221, crushing rollers 251 are fixedly inserted into the inner surface walls of the two groups of bearing seats 25, and one side of the outer wall of the two crushing rollers 251 is fixedly connected to a driving motor A26, and the bottoms of the two driving motors A26 are fixedly connected to the top of the placing frame 21, and a control component 27 is set at the top of the placing frame 21; The conveying mechanism 3 includes a group of fixed rods 31, and the top of the mounting body bottom plate 1 is fixedly connected to the bottom of the group of fixed rods 31, the top of the group of fixed rods 31 is fixedly connected to a conveying component 32, and the top of the conveying component 32 is fixedly connected to a collecting hopper 33.

[0026] In this embodiment, when the equipment is in use, some larger block products in cement production are inverted inside the funnel plate 23. Under the action of gravity, the block cement can be kept to gather at the bottom center of the funnel plate 23. When it reaches the bottom, the two external drive motors A26 are energized, and the internal rotor can be kept to rotate quickly inside the stator by electromagnetic force, so as to drive the two crushing rollers 251 to rotate towards each other. The two crushing rollers 251 are supported by two sets of bearing seats 25, which can provide good support points for the rotation of the two crushing rollers 251. When the material enters between the two crushing rollers 251, it can rely on the extrusion of the two crushing rollers 251 to keep the material crushed. The crushed product material can fall into the collecting hopper 33 through the output port 24 at the bottom thereof, and enter the interior of the conveying assembly 32 by gravity. In the interior of the conveying assembly 32, the driving device is driven to keep the conveyor belt rotating, and the material falling on the top of the conveyor belt moves to the right end. Finally, the crushed material can be collected inside the grinding and rejecting mechanism 4 for the next step of processing.

[0027] The working principle of the whole mechanism is as follows: first, when the equipment is in operation, large cement blocks are placed in the funnel plate 23. With the help of gravity, these blocks gradually gather to the bottom center of the funnel plate 23. Once they reach the bottom, two crushing rollers 251 driven by an external drive motor A26 rotate at high speed in the stator under the action of electromagnetic force, driving the two crushing rollers 251 to rotate in opposite directions. The crushing rollers 251 are supported by a solid bearing seat 25 to ensure stable rotation. When the material enters between the two rollers, it is subjected to a strong squeezing force to achieve preliminary crushing. Then, The crushed material falls into the collecting hopper 33 through the output port 24 at the bottom, and is guided by gravity into the conveying assembly 32. In the conveying assembly 32, the driving device drives the conveyor belt to operate, and the material is conveyed to the right side, and finally collected in the grinding and rejecting mechanism 4, ready for further processing. After entering the grinding and rejecting mechanism 4, the bottom fixed plate 474 firmly installs the driving motor B473 on the base frame 41. After the motor is energized, its output end drives the linkage rod 472 to rotate, thereby driving the grinding disc 48 to rotate. At the same time, the two rotating motors 464 respectively drive the driving rod 461 and The grinding roller 462 rotates. When the grinding roller 462 contacts the cement blocks on the grinding disc 48, inter-particle crushing is performed. At the same time, the centrifugal force generated by the rotation of the grinding disc 48 causes the fine particles to move to the edge. In the annular cavity formed between the grinding disc 48 and the top mounting frame 47, the annular air pipe 49 uses the high-pressure gas provided by the compressor to spray through the air nozzle 491 to form an air flow. This air flow circulates in the annular cavity, effectively helping the powdered cement particles to be blown into the protective outer frame 42. The separator 43 installed on the top is started synchronously, and the negative pressure environment generated by it attracts and collects the protective outer frame 47. 2, the smaller cement particles in the gas pass through the filter 433 into the internal negative pressure channel 432, and are finally transported to the output pipe 431 under the action of negative pressure to realize the collection and discharge of cement products. As for the larger particles attached to the filter 433, the built-in scraper blades 434 automatically start and rotate to effectively scrape off these particles, so that they fall into the guide bucket 45 at the bottom under the action of gravity. These particles are then redirected to the grinding disc 48 for more detailed grinding treatment to ensure that all materials can reach the expected fineness standard.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
