[0002] Cement is a kind of powdery inorganic cementitious material, which can be mixed into a slurry after adding water, can be hardened in air or water, and can firmly cement sand, stone and other materials together. Cement is widely used in civil construction, water conservancy, national defense and other engineering fields, and is one of the important basic raw materials in national economic construction. With the continuous progress of science and technology and the continuous optimization of process, the production efficiency and product quality of cement are continuously improved. As described above, the production of cement involves multiple complex process links and key equipment, and each link has an important influence 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. The particle crushing and impurity removal in cement production are key links to ensure the quality of cement. By optimizing the grinding equipment, improving the grinding process, adopting effective impurity removal methods and reasonably designing the production equipment, the fineness and uniformity of cement particles can be significantly improved, and impurities can be effectively removed, so that the overall quality of cement products is improved.

The particle crushing and impurity removal device for cement production can effectively crush the cement, and the ferrous impurities such as hair and particles in the cement are completely filtered out, improving the quality of the cement after production; such as Chinese Patent No: CN112756346A, a cement scaling cleaning device for cement production is provided, which includes a ring member and a conveying pipe fixedly connected to the ring member through a plurality of supporting frames, at least two receiving sleeves are sleeved on the conveying pipe and are in sliding cooperation with the conveying pipe, the receiving sleeves are fixedly connected to the mounting frame, a first driving mechanism is arranged on the mounting frame and connected to the conveying pipe; a plurality of spades are arranged at the outer side end of the ring member, the spades are slidably connected to the ring member through a guide assembly, and a reciprocating driving assembly is further connected to the spades.

[0004] In the process of refining cement production, the purity and particle size control of raw materials are the key to ensure the quality of the final product. However, large particle materials and fine impurities are inevitably mixed in the raw materials. If these elements are not properly treated and directly put into the production line, the fineness uniformity and physical strength of the cement will be directly weakened, thereby affecting the overall performance and application effect. The traditional process generally relies on a complex multi-stage crushing and screening process, which not only increases the complexity and energy consumption of the production line, but also is not effective in removing fine impurities, making it difficult to achieve the ideal purity standard, and there are many limitations in grinding.

[0042] In this embodiment, when the cement material after crushing enters the inside of the grinding and removing mechanism 4, first the fixed plate 474 at the bottom can fix the driving motor B 473 at the bottom of the chassis 41, and keep the fixed state of the driving motor B 473, when the driving motor B 473 is in the state of being powered, its output end can drive the linkage rod 472 to rotate, and make the linkage rod 472 as a medium to keep the grinding disc 48 rotating, and after the cement material falls on the top of the grinding disc 48, the two rotating motors 464 at the other end are powered to drive the driving rod 461 and the grinding roller 462 on the side of the outer wall to rotate, and when the grinding roller 462 contacts the cement block on the top of the grinding disc 48, the particles are crushed by the extrusion of the two grinding rollers 462, and in this process, under the action of the rotating centrifugal force of the grinding disc 48, the smaller and lighter cement particles can move to the edge.

Embodiment two

[0046] According to Figure 1 , Figure 2 ,Figure 3 、 Figure 4 and Figure 5 As shown in FIGS. 1-3, the crushing mechanism 2 comprises a placing rack 21, the top of the installation main body bottom plate 1 is fixedly connected with the bottom of the placing rack 21, the inner surface wall of the placing rack 21 is fixedly inserted with an operation frame 22, the inside of the operation frame 22 is pre-provided with two groups of driving grooves 221, the top of the operation frame 22 is fixedly communicated with a funnel plate 23, the bottom of the operation frame 22 is provided with an output port 24, the inner surface wall of the two groups of driving grooves 221 is fixedly inserted with a bearing seat 25, the inner surface wall of the two groups of bearing seats 25 is fixedly inserted with a crushing roller 251, the outer wall of the two crushing rollers 251 is fixedly connected with a driving motor A 26 on one side, and the bottom of the two driving motors A 26 is fixedly connected with the top of the placing rack 21, and the top of the placing rack 21 is provided with a control assembly 27.

[0047] The conveying mechanism 3 comprises a group of fixed rods 31, and the top of the installation main body bottom plate 1 is fixedly connected with the bottom of the group of fixed rods 31, the top of the group of fixed rods 31 is fixedly connected with a conveying assembly 32, and the top of the conveying assembly 32 is fixedly communicated with a collecting hopper 33.

[0048] In this embodiment, first, the device is used, and some larger block-shaped products in cement production are placed in the inside of the funnel plate 23. Under the action of gravity, the block-shaped cement can be collected to the bottom center of the funnel plate 23, and when it reaches the bottom, the rotor inside can be quickly rotated in the stator under the electrification of the two driving motors A 26 outside, so as to drive the two crushing rollers 251 to rotate towards each other, and the two crushing rollers 251 are supported by the two groups of bearing seats 25, which can provide a good support point for the rotation of the two crushing rollers 251. When the material enters between the two crushing rollers 251, the material can be crushed by the extrusion of the two crushing rollers 251.

[0049] The crushed product material can fall into the collecting hopper 33 through the output port 24 at the bottom, enter the inside of the conveying assembly 32 by gravity, and rotate under the driving of the driving device, so that the material falling on the top of the conveying belt moves to the right end, and finally the crushed material can be collected in the grinding and removing mechanism 4 for the next step of processing.

[0050] The working principle of the entire mechanism is as follows: First, during equipment operation, large cement blocks are placed inside the funnel plate 23. With the help of gravity, these blocks gradually converge towards the bottom center of the funnel plate 23. Once they reach the bottom, two crushing rollers 251, driven by an external motor A26, rotate at high speed within their stators under electromagnetic force, causing the two crushing rollers 251 to rotate towards each other. The crushing rollers 251 are supported by robust bearing seats 25, ensuring stable rotation. When material enters between the two rollers, it is subjected to strong extrusion force, achieving initial crushing. Subsequently... The crushed material falls into the collection hopper 33 through the bottom outlet 24 and is guided by gravity into the conveying assembly 32. Inside the conveying assembly 32, the drive equipment drives the conveyor belt to rotate, and the material is conveyed to the right side, eventually gathering in the grinding and rejection mechanism 4 for further processing. After entering the grinding and rejection mechanism 4, the bottom fixing plate 474 securely mounts the drive motor B473 onto the base frame 41. After the motor is powered on, its output end drives the linkage rod 472 to rotate, thereby driving the grinding disc 48 to rotate. At the same time, two rotary motors 464 respectively drive the drive rod 461 and... The grinding roller 462 rotates, and when it contacts the cement lumps on the grinding disc 48, it performs intergranular crushing. Simultaneously, the centrifugal force generated by the rotation of the grinding disc 48 causes the fine particles to move towards the edge. Within the annular cavity formed between the grinding disc 48 and the top mounting frame 47, the annular air pipe 49 uses high-pressure gas provided by the compressor, which is ejected through the air nozzle 491 to form an airflow. This airflow circulates within the annular cavity, effectively assisting in blowing the powdered cement particles into the protective outer frame 42. The top-mounted separator 43 starts simultaneously, and the negative pressure environment it generates attracts and collects the protective outer frame 42. The gas containing powdered cement in section 2 has smaller cement particles that pass through filter screen 433 into the internal negative pressure channel 432. Under negative pressure, these particles are then transported to the output pipe 431 for collection and discharge of cement products. For larger particles attached to filter screen 433, the built-in scraper blades 434 automatically start and rotate to effectively scrape off these particles, causing them to fall into the bottom guide hopper 45 under gravity. These particles are then redirected to the grinding disc 48 for finer grinding, ensuring that all materials meet the expected fineness standards.

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