Then biaxial blades mixer produce and biaxial blades mixer arises at the historic moment. This machine is widely used in the food, feed, chemical, pharmaceutical, pesticide, and other industries powder, granule, flake, miscellaneous and mixed sticky materials, Mixed cycle is short, mixed uniformity: general materials in 50 ~ 90S time mixing degree than 5%, reduce CV hybrid time and improve production efficiency, animal feed factory. Loading quantity variable range: loading coefficient for 0.3 ~ 0.8 variable range, and many different proportion and granularity in materials such as mixing, Mixing machine: do not produce segregation in 1 minute after mixing, continue to mix materials not occurred phenomenon, and not because of classification, such as sexual difference is big size and segregation, A fast, residues by four small: bottom door struc
