This model is a new generation model developed based on many years of experience in producing and selling various types of rice milling and crushing machines and sufficient market research. The 6NF-4.0 rice mill has revolutionized the traditional rice milling process. It adopts a new rice roller with a hexagonal rice screen design, which effectively improves the quality of rice and reduces the broken rice rate. The independent negative pressure fan structure makes the rice bran separation cleaner. Combined with the 9F-21 crusher, rice milling and crushing share the same power, and the operation is simple.
