Three-axis vertical mixer used in chemical, coal, refractory, building materials, metallurgy, chemical industry, for stirring kneading been formulated into water, binders, coal, in front of the material had been basically mixed, so stick caking agent better play role in enhancing the density of the material to improve the thin plastic material, will help improve the quality of products is the key equipment of coal production line. Mixer is based on absorbing foreign advanced technology similar equipment developed into a new improved stirring kneading equipment, with kneading effect, low energy consumption, generally horizontal mixer planetary mixer or compulsory supporting the use of better finish material mixing, kneading operations. Three-axis vertical mixer works: mixer consists of motor, reducer, flexible coupling, gear box, took the initiative from the agitator shaft, cylinder, base, frame and other components. Blender is the motor power transmission line reducer, flexible coupling and transmission gear pair, driven initiative, driven agitator shaft for rotational motion in the opposite direction, initiative and driven agitator shaft cross stratification stirring rod and blade configuration, the work process pulverized coal (or other material) is arranged by a certain ratio, mixing water and a binder material, forced by a planetary mixer or horizontal mixer After stirring, added to the mixer by the belt conveyor, the material is added to the feed port by initiative, driven shaft and blade stirring rod were thrown on the material stirred pinch slack work, material through the discharge hopper discharge after kneading, kneading can achieve continuous operation. Vertical-axis type mixer type is No. 330,530, 15,30 tons of production capacity, etc. too.
