The work of WY series vertical mixer is to use the rapid rotation of the screw to lift the raw materials from the bottom of the barrel from the center to the top, and then throw them away in an umbrella shape and return to the bottom. In this way, the raw materials are stirred up and down in the barrel, and a large number of raw materials can be mixed evenly in a short time. The hot air is blown into the mixing barrel through the heating device to quickly dry the tumbling materials in the mixing barrel.
