Embodiment Construction

[0023] figure 1 The drive unit 10 shown, figure 2 The drive unit 110 shown and image 3 The drive unit 210 shown is intended to be figure 1 Part of the vertical agitated mill 11 is shown in the middle.

[0024] The mill 11 comprises a grinding bucket 12 and a grinding tool 13 rotatable relative to the grinding bucket 12 along a first vertical axis 14 .

[0025] The rotating grinding tool 13 is located inside the grinding barrel 12 . For example, the grinding tool comprises a helical blade or a set of grinding discs stacked along said first axis 14 , or grinding fingers perpendicular to said first vertical axis 14 .

[0026] The upper wall 18 of the grinding bucket 12 includes a bore 20 coaxial with the first vertical axis 14 . A grinding tool 13 passes through said hole 20 , the upper end 22 of said grinding tool 13 forming a protrusion above the upper wall 18 . For example, the upper end 22 is in the form of a fastening flange.

[0027] The upper end 22 of the rotatin...

Abstract

The invention relates to a drive device (10) for a vertical stirring mill (11), the drive device comprising: a main housing (24); a motor (50); A rotating element (28) rotatable by a vertical axis (14); said rotating element is fixed to the rotating grinding tool (13) of the vertical stirring mill. The rotating element includes a substantially horizontal rotating plate (34); and the main housing includes an axial stop (36) for axially guiding the rotating element; the rotating plate is arranged to be supported on the axial stop On the stopper, so that the axial stopper can bear the axial force exerted on the grinding tool during the operation of the vertical stirring mill.

Description

technical field [0001] The invention relates to a drive device for a vertical stirring mill. [0002] More specifically, the present invention relates to a driving device comprising a main housing, a motor, and a rotating element rotatable relative to the main housing around a first vertical axis, the rotating element being driven to rotate by the motor. The rotating element is fixed or can be fixed to the rotating grinding tool of the vertical stirring mill. Background technique [0003] Vertical agitator mills are used in the mining industry to grind raw materials. Grinding tools, such as helical blades, rotate within the grinding barrel. [0004] At this time, the solution for very high power drives uses a motor assembly with a vertical axis mounted on a planetary gear reducer above the grinding tool. The grinding tool is axially supported on the outside of the gear reducer, which only carries the rotational force. [0005] The vertical volume of such mills is very la...
