[0021] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.
[0022] Embodiment: A new energy-saving ball mill, see Figures 1 - 3 As shown, it includes a base frame 1, a rotating shaft 2, a permanent magnet motor 3, a ball mill barrel 4, a pulley group 5, a feeding pipe 6, a protective cover 7, a high wear-resistant lining plate 8 and a noise reduction cotton 9. The base frame 1 is symmetrically arranged on the left and right. The rotating shaft 2 is rotatably arranged between the front parts of the two base frames 1. The permanent magnet motor 3 is installed on the base frame 1 on the left. The output shaft of the permanent magnet motor 3 is connected to the rotating shaft 2 through a coupling. The permanent magnet motor 3 has an energy-saving function. A ball mill barrel 4 is rotatably arranged between the rear parts of the two base frames 1. The rotation of the ball mill barrel 4 can drive the internal steel balls to roll. Under the centrifugal force The material can be crushed under the action, a pulley group 5 is symmetrically installed between the ball mill barrel 4 and the rotating shaft 2, and the pulley group 5 consists of two pulleys and a flat belt. The left part of the ball mill barrel 4 is rotatably connected to a feed pipe 6, and the feed pipe 6 is L-shaped. The right side of the ball mill barrel 4 is covered with a protective cover 7, and a plurality of protrusions are arranged at intervals on the protective cover 7. A high wear-resistant lining plate 8 is connected to the inner side of the ball mill barrel 4, and a noise reduction cotton 9 is connected to the outer wall of the ball mill barrel 4. The noise reduction cotton 9 can reduce the noise generated by the rotation of the ball mill barrel 4, and the noise reduction cotton 9 wraps the outer wall of the ball mill barrel 4.
[0023] When the device needs to be used, first place the device at the designated position, then put an appropriate amount of steel balls into the ball mill barrel 4 through the feed pipe 6, and put an appropriate amount of materials into the ball mill barrel 4 through the feed pipe 6. Subsequently, people start the permanent magnet motor 3. The output shaft of the permanent magnet motor 3 rotates to drive the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 can drive the ball mill barrel 4 to rotate through the pulley group 5. The rotation of the ball mill barrel 4 can drive the internal steel balls to roll. Under the action of centrifugal force, the materials inside the ball mill barrel 4 can be crushed and ground by the steel balls. Since the permanent magnet motor 3 directly cancels the reducer, inorganic transmission device and transmission, the equipment structure is simplified. Therefore, the stability of the equipment is improved and it has the function of energy saving. While the materials are being crushed, the highly wear-resistant lining plate 8 plays a role in protecting and wearing resistance, which can reduce the wear of the inner wall of the ball mill barrel 4. The noise reduction cotton 9 plays a role in noise reduction, reducing the noise generated when the ball mill barrel 4 is crushed. When the crushing and grinding are completed, turn off the permanent magnet motor 3, then open the protective cover 7, and finally take out the steel balls and the crushed materials.
