The invention discloses a
tower mill. A technical scheme adopted by the
tower mill is that the
tower mill comprises a main motor, a speed reducing device, a
supporting system, a cylinder, a door, a spiral stirrer and protective lining plates, wherein the main motor is connected with the speed reducing device, the speed reducing device is arranged on the
supporting system, the
supporting system is a completely-closed structure, a driving shaft is arranged in the supporting
system, the upper end of the driving shaft is connected with the speed reducing device, and the lower end of the driving shaft is connected with a screw rod shaft of the spiral stirrer by virtue of a shaft sleeve; the protective lining plates are arranged on the inner walls of the cylinder and the door; the bottom end of a first
spiral blade group and the bottom end of a second
spiral blade group are connected with a double-head material picking blade which is fixedly arranged on the screw rod shaft; a
discharge opening and a feed opening are formed in the cylinder; and the door is movably connected with the cylinder. By adopting the tower mill disclosed by the invention, the
grinding efficiency of the tower mill can be significantly improved, the service life of wear-out parts can be prolonged, the loss of a
grinding medium can be reduced, the
assembly and use of the tower mill can be facilitated, the
mechanical efficiency of the tower mill can be improved, and the manufacturing cost of the tower mill can be reduced.
