[0002] Cat litter is a material used by cats to bury feces and urine. It has good water absorption and is usually used with a litter box. An appropriate amount of cat litter is poured into the litter box. When a trained cat needs to defecate, it will step into the litter box and deposit its feces on the litter box. Cat litter is usually made of paper pulp granulated into small particles to simulate sand and provide water absorption. Some granules also use physical desiccants such as silica gel. Chemical products such as antibacterial agents, deodorants, and preservatives are often added. Cat litter will clump when it comes into contact with water. Most cat litter will get on the feet of cats and carry it elsewhere, so please make sure to clean it frequently. During the cat litter production process, a ring die pelletizer is required for its processing.

A material discharge channel 10 is formed at the intersection of the splash guide plates 5. The material discharge channel 10 is arranged just above the feed port on the upper part of the filter screen 12. An inner material guide plate 13 is also provided at the upper opening of the filter screen 12, and the two inner material guide plates 13 are arranged in an inverted eight-shaped distribution. The anti-splash guide plate and the material discharge channel 10 facilitate the accurate introduction of materials into the feed end of the crushing roller 11, which is beneficial to improving the crushing efficiency. The anti-splash guide plate can also prevent the rotating crushed material from splashing out, thereby improving the safety of crushing. At the same time, the narrower material discharge channel 10 can be used to perform preliminary filtration of the material, and larger materials remain on the upper part of the anti-splash guide plate to prevent larger materials from affecting the crushing efficiency of the crushing roller 11.

[0023] like Figure 1 、 Figure 2 and Figure 3 As shown, in order to extrude and crush the larger materials filtered on the upper part of the anti-splash guide plate, a crushing plate 8 is also provided on the upper side of the first anti-splash guide plate 4 and the second anti-splash guide plate 5 through a cylinder 7, and the lower end surfaces of the crushing plate 8 are respectively slidingly arranged parallel to the upper surfaces of the first anti-splash guide plate 4 and the second anti-splash guide plate 5.
