[0030] The feed is sent to the upper part of the crushing wheel 7 and crushed by the crushing wheel 7. After crushing, the feed falls onto the grinding plate 9 between the two crushing wheels 7 for further grinding. The ground feed falls onto the first filter plate 3 and is filtered and screened through the first filter plate 3. By rotating the conveyor belt 5, the conveyor belt 5 drives the pushing plate 6 to slide across the upper part of the first filter plate 3, so that the large pieces of feed that have not been filtered out are pushed by the pushing plate 6 above the feeding hopper 8 and then fall back onto the crushing wheel 7 for further crushing and processing.

[0031] Please refer to Figure 6 , on the inner wall of the processing bin 2, a grinding plate 9 is installed. The grinding plate 9 is located between the crushing wheel 7 and the first filter plate 3, and a through groove is formed in the upper part of the grinding plate 9.
