[0036] The bottom plate of the reducer 8 is fixedly installed on the frame 1 by screws.

[0037] Operation of a symmetric roller barrel ball mill with hoisting and positioning:

[0038] Hoisting of the roller barrel 5;

[0039] Move the roller barrel 5 to the side of the symmetric roller barrel ball mill with hoisting and positioning, and pull the roller barrel support device 4 outwards to the roller barrel hoisting position. Operate the hoisting device 6 to place the roller barrel 5 on the roller barrel support device 4 to complete the hoisting process of the roller barrel 5.

[0040] Positioning and installation of the roller barrel 5:

[0041] After placing the drum 5 on the drum support device 4, rotate the drum 5 so that the two U-shaped slot holes 5.2 on the drum 5 are exactly aligned with the two pins 7.5 on the positioning sleeve device 7. Then, forcefully push the drum 5 towards the positioning sleeve device 7. When the drum 5 is pushed in place, rotate the drum 5 by a certain angle and release the thrust. At this time, the flange of the drum 5 is restricted between the push plate 7.3 and the pin 7.5 under the spring force of the compression spring 7.4. Then, slowly rotate the drum 5. When it rotates to the point where the two U-shaped notches 5.1 on the flange of the drum 5 are aligned with the two pins 7.5 on the positioning sleeve device 7, the drum 5 is pushed backward under the action of the spring force, driving the drum support device 4 to move backward on the linear guide 2. The two pins 7.5 on the positioning sleeve device 7 are inserted into the two U-shaped notches 5.1 on the flange of the drum 5. Then, rotate the drum 5, and it is very difficult to rotate the drum 5. At this time, the drum 5 is positioned and fixed.

[0042] Operation of the drum ball mill with hoisting and positioning device:

[0043] After turning on the power, the power display light on the control panel of the symmetric drum ball mill with hoisting and positioning lights up, indicating that the power is connected. After setting the operating parameters on the control panel, click the start button, the motor rotates, driving the output shaft of the speed reducer to rotate. The output shaft of the speed reducer drives the positioning sleeve 7.1 to rotate. The drum 5 rotates together with the positioning sleeve device 7 under the action of the two pins 7.5 on the positioning sleeve device 7 and the frictional force of the flange surface of the drum 5. At this time, the grinding balls in the drum 5 grind the materials in the drum 5.

[0044] A symmetric drum ball mill with hoisting and positioning provided by the present utility model has the following beneficial effects:

[0045] The symmetric drum ball mill with hoisting and positioning provided by the present utility model adopts the structural design of the positioning sleeve device 7 to make the drum work in a closed manner, avoiding the falling of materials outside the drum; adopting the hoisting device 6, the drum can be placed on the drum support device 4, and the hoisting process of the drum can be completed after the materials are loaded. The ball mill has a positioning sleeve device 7, which is not an open design. Therefore, during the grinding process, the materials will not fall around the drum ball mill, and there is no material loss. Adopting a symmetric structure design, one speed reducer drives two drums to grind and rotate, improving the grinding efficiency.

[0046] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
