Screw Coal Unloader with Capacity 400～1500t/h
1. Product Description
AOTUO-XM environmentally friendly screw coal unloader is independently developed and manufactured by AOTUO in 2018. It has been successfully applied to coal conveying system of a domestic power plant and is the first set of coal unloader in China. Relying on the two-way horizontal rotation of the rotary tower, the elevation of the horizontal beam on the tower, the swing of the vertical arm forward and backward and the walking of the gantry crane, the feeder can realize the three-dimensional motion tracking of material position, and then use the vertical screw machine to lift the material to the horizontal screw machine, and then automatically unload the material in the warehouse to the shore by the discharging device.
