The design of the handle 28 allows workers to easily grip it during operation, providing a convenient way to quickly open the protective door 14 when needed for equipment inspection, maintenance, or cleaning. This further enhances the safety of use. For comfort, the outer wall of handle 28 is wrapped with a non-slip sleeve 29. The non-slip sleeve 29 is made of soft and high-friction rubber material, and its surface is specially textured, which greatly increases the contact area and friction with the hand, effectively avoiding operational errors caused by hand slippage, and ensuring that the process of opening the protective door 14 is safer and more stable. At the connection between the protective door 14 and the outer shell 7, the inner wall of the fixing block 2 15 is threaded and connected to the screw 2 30. The outer wall of the screw 2 30 is connected to the bolt 31 through thread engagement, fixing the protective door 14 to the outer shell 7, so that it is not easy to open during the operation of the equipment, avoiding personal injury caused by accidental contact with the high-speed rotating parts inside, and providing a guarantee for the safe operation of the entire crushing equipment.

[0039] Working Principle: Material enters the crusher through inlet 1. The bottom of inlet 1 is welded to the protective shell 3, creating a safe and stable environment for material conveying. Motor 4, located behind the protective shell 3, starts working, converting electrical energy into mechanical energy. When motor 4 starts, its output power drives the rotating rod 5 to rotate. The continuous rotation of the rotating rod 5 causes the conveying blades 6 to move as well. The conveying blades 6, with their unique shape and the thrust generated by rotation, push the material forward along the internal channel of the protective shell 3, ultimately conveying the material from inlet 1 to the crushing device inside the outer shell 7. After the material enters the outer shell 7, motor 8 also converts electrical energy into mechanical energy. When motor 8 starts, it provides strong power to the rotating shaft 9, driving... The rotating shaft 9 rotates at high speed, which further drives the blade 10 to rotate rapidly. The high-speed rotating blade 10 cuts and crushes the material entering the housing 7, gradually breaking it down into fine particles. The crushed material is output through the discharge port 17. The fixing block 3 18 fixes the housing 7 to the fixing plate 19. The fixing plate 19 can disperse the vibration generated during the operation of the equipment, prevent the equipment from shaking due to vibration, ensure the stable operation of the equipment, and ensure that the crushed material can be smoothly discharged from the discharge port 17. The support column 20 and the support foot 21 provide further stable support for the equipment, ensuring that the equipment remains stable during operation, providing a solid guarantee for the efficient and safe operation of the entire material processing process.

[0040] The filter screen 203 uses regularly shaped filter holes 206 to screen the pulverized material by particle size. When the pulverized material falls onto the filter screen 203, particles that meet the particle size standard can pass smoothly through the filter holes 206 and fall downwards to enter the subsequent collection and processing process. Particles that do not meet the standard are intercepted on the filter screen 203, thus achieving the screening and filtration of materials and separating qualified and unqualified materials. The groove 201 fits snugly against the outer wall of the filter screen 203 to prevent material leakage from the gap between the filter screen 203 and the outer shell 7 or uneven screening during the screening process. The threaded hole 202 and screw 204 cooperate to further fix the filter screen 203 inside the groove 201, ensuring that it will not shift or loosen even when the equipment is running continuously and the material is constantly impacting it. When it is necessary to disassemble, maintain and repair the filter screen 203, the handle 205 can easily and quickly remove the filter screen 203 from the equipment, improving the efficiency of equipment maintenance and repair and contributing to the long-term stable operation of the entire material processing equipment.
