摘    要
隨著現(xiàn)代化飼料工業(yè)的發(fā)展， 飼料廠規(guī)模不斷擴大，對混合機混合均勻度的要求不斷提高 隨著飼制液體添加量增加， 傳統(tǒng)的臥式雙螺帶混合機已不能滿足上述要求．于是新一代高性能雙軸槳葉式混合機便應(yīng)運而生從而雙軸槳葉式混合機應(yīng)運而生。該機器廣泛用于飼料、糧食、化工、醫(yī)藥、農(nóng)藥等行業(yè)中粉狀、顆粒狀、片狀、雜狀及粘稠狀物料的混合； 混合周期短、混合均勻度高：一般物料在50～90S時間內(nèi)混合均勻度CV≤5%，減少了混合時間，提高了飼料廠生產(chǎn)效率； 裝填量可變范圍大：裝填系數(shù)可變范圍為0.3～0.8，適用與多行業(yè)中不同比重、粒度等物料的混合； 混合不產(chǎn)生偏析：該機在1分鐘內(nèi)混合均勻后，繼續(xù)混合物料不發(fā)生分級現(xiàn)象，且不會因為比重、粒度等物性差別大而產(chǎn)生偏析； 出料快、殘留量小：底部采用四開門結(jié)構(gòu)，排料迅速、殘留少； 液體添加量大：添加30%的液體仍能將物料混合均勻，即能混合粘稠物料； 采用獨特的鏈條張緊機構(gòu)，裝拆、調(diào)節(jié)快捷而方便； 排料門密封可靠：排料門采用氣囊密封，密封可靠、使用壽命長，更換方便； 采用W形混合室，內(nèi)置風(fēng)道，整體式機座，側(cè)置檢修門，造型美觀，裝拆檢修方便。

Biaxial blades efficient mixing machine
Abstract: Along with the development of modern industry, animal feed factory continues to expand the scale of mixer, mixing with requirement of improving forage additive quantity of liquid, traditional horizontal double screw with mixer already cannot satisfy the requirement of new generation of high performance. 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 structure, discharging quick, residues, Liquid add quantity: 30% of the liquid can still be mixing materials, which can be mixed sticky materials, Adopt unique chain tensioner, installation, fast and convenient adjustment, Discharging door sealing is reliable, discharging the airbag seal, sealing is reliable, long service life, easy to change, Adopting W shaped the mixing chamber, built-in duct, the integral base-plate, side for the access door, beautiful modelling, installation maintenance convenience.
