Description

Technical Field

[0001] This utility model relates to the field of cement product processing technology, and in particular to a raw material crushing and grinding equipment for cement product processing. Background Technology

[0002] Cement is a powdered, hydraulic, inorganic binder. When mixed with water, it forms a paste that hardens in air or water, and effectively binds materials such as sand and stone together. Early mixtures of lime and volcanic ash were very similar to modern lime-volcanic ash cement. Concrete made with this binder, using crushed stone, not only has high strength after hardening but also resists erosion from fresh or salt water. For a long time, it has been widely used as an important binder in civil engineering, water conservancy, and other projects. Cement products typically require the raw materials to be crushed and ground before processing.

[0003] In the existing technology, most commonly used cement product raw material crushing and grinding equipment performs coarse crushing and fine crushing in stages, resulting in low production efficiency; and it cannot dynamically adjust the particle size of the raw material, resulting in poor adaptability.

[0004] To address this issue, a raw material crushing and grinding device for cement product processing is proposed. Utility Model Content

[0038] Working Principle: Cement raw materials are fed into the crushing chamber 1 through the feed hopper 101 via an external conveying device. The raw materials first enter the primary crushing chamber 102. Driven by motor 301, the mounting shaft 302 drives the mounting plate 303 and mounting rod 304 to rotate rapidly, causing the crushing hammers 305 to crush the cement raw materials entering the primary crushing chamber 102. The initially coarsely crushed cement raw materials fall into the secondary crushing chamber 103. Driven by motor 401, the transmission roller 402 and the conical spiral teeth 403 rotate to further crush the coarsely crushed raw materials. By integrating coarse and fine crushing, production efficiency is improved. After secondary fine crushing, the cement raw materials fall into the secondary crushing chamber 103. The material falls into the conveying trough 104 and is transported to the grinding chamber 601 through the discharge port 105 and the inlet port 602 by the rotating auger blades 503 driven by the motor 501 and the transmission rod 502. Inside the grinding chamber 601, the male grinding head 704 rotates under the drive of the hydraulic motor 701 and the transmission rod 703. The male grinding head 704, together with the female grinding head 702, grinds and crushes the cement product raw materials entering the grinding chamber 601. At the same time, according to the needs, the forward and reverse motors 606 are started to drive the threaded rod 607 to rotate, thereby adjusting the height of the moving ring 604. Simultaneously, the hydraulic motor 701 is moved to adjust the height of the male grinding head 704 within the female grinding head 702, thereby adjusting the particle size of the grinding and crushing process and improving the applicability of the device.
