In recent years, they have also replaced ball mills as the equipment for two-stage grinding and three-stage grinding. Compared with ball mills, tower mills have the characteristics of simple structure, small footprint, high energy utilization, and fine product particle size. They have been widely recognized in the powder industry and have broad market prospects. However, tower mills require high-speed rotating rotors when in use.

[0003] The existing technology has the following problems:

[0004] When using a high-speed rotating rotor in a tower mill, it is not possible to effectively grind particles in different zones according to grinding requirements. In addition, existing devices are bulky, costly, and not easy to promote and use. Furthermore, the high-speed rotating rotor in a tower mill cannot effectively avoid over-grinding.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a high-speed rotating rotor for a tower mill. Through the action of a motor, the rotating shaft can drive several grinding rotors to rotate on the inner wall of the liner. With the cooperation of several stator rings, the particles are ground in sections. The central part is a low-intensity grinding zone, and the outer part is a high-intensity grinding zone. In use, the particles can be separated into fine particles and coarse particles by centrifugal force. Through the action of centrifugal force, the fine particles are pushed into the high-intensity grinding zone, while the fine particles move upward on the inner side of the vortex near the rotating shaft, which facilitates selective grinding. At the same time, it has a small footprint, simple structure design, and low cost.

[0017] 2. This utility model provides a high-speed rotating rotor for a tower mill. Through the action of the stator ring, the inner wall of the liner is divided into multiple grinding zones, which are arranged sequentially from bottom to top. Therefore, after each grinding, the particles are screened, and the particles that reach the target fineness enter the next process through the outlet without being ground finer. This helps to improve the product recovery rate, thereby avoiding over-grinding. The operation is simple and easy to maintain. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown, a high-speed rotating rotor for a tower mill includes a mill frame 1. Support frames 2 are fixedly connected to the left and right parts of the lower surface of the mill frame 1. Support seats 3 are fixedly connected to the lower surfaces of the two support frames 2. A grinding assembly 5 is fixedly connected to the inner wall of the middle part of the mill frame 1 and the grinding assembly 5 is located between the two support frames 2. A grinding media hopper 4 is fixedly connected to the left part of the upper surface of the mill frame 1 and the grinding media hopper 4 is located to the left of the grinding assembly 5.

[0026] First, the device is firmly fixed to the ground by the support frame 2 and the support base 3. Then, the grinding media hopper 4 allows the grinding media to enter the interior of the grinding component 5. Under the action of the grinding component 5 and the grinding media, the particles can be uniformly ground.

[0027] like Figure 2 , Figure 3 As shown, the grinding assembly 5 includes a grinding cylinder 51, the outer wall of which is fixedly connected to the inner wall of the mill frame 1, and a reducer 52 is fixedly connected to the upper surface of the grinding cylinder 51; a motor 53 is fixedly connected to the upper surface of the reducer 52, and an overflow port 54 is fixedly connected to the right side of the reducer 52; a plurality of rotor sleeves 57 are fixedly connected to the outer wall of the rotating shaft 56, and grinding rotors 58 are fixedly connected to the outer walls of the plurality of rotor sleeves 57; the outer walls of the plurality of grinding rotors 58 are respectively movably sleeved with the inner wall of the liner plate 59.

[0028] The motor 53 drives the rotating shaft 56 to rotate several grinding rotors 58 on the inner wall of the liner 59. With the cooperation of several stator rings 510, the particles are ground in sections. The central part is a low-intensity grinding zone, and the outer part is a high-intensity grinding zone. In use, the particles are separated into fine particles and coarse particles by centrifugal force. The fine particles are pushed into the high-intensity grinding zone by centrifugal force, while the fine particles move upward on the inner side of the vortex near the rotating shaft 56 and are discharged from the top outlet.

[0029] A feeding system 55 is fixedly connected to the lower surface of the grinding cylinder 51, and a bottom cover 511 is fixedly installed on the bottom of the inner wall of the grinding cylinder 51. The upper surface of the bottom cover 511 is fixedly installed on the lower surface of the liner 59.

[0030] The feeding system 55 enables the material to enter the inner cavity of the grinding cylinder 51.

[0031] like Figure 4 , Figure 5 As shown, a liner 59 is fixedly connected to the inner wall of the grinding cylinder 51, and a plurality of stator rings 510 are fixedly connected to the inner wall of the liner 59; a rotating shaft 56 is fixedly connected to the output end of the motor 53, and the outer wall of the upper part of the rotating shaft 56 is rotatably connected to the inner cavity of the grinding cylinder 51; a plurality of grinding rotors 58 are respectively located between a plurality of stator rings 510, and the stator rings 510 form a separate grinding area around each grinding rotor 58;

[0032] The stator ring 510 divides the inner wall of the liner 59 into multiple grinding zones, arranged sequentially from bottom to top. Therefore, after each grinding, the particles are screened, and the particles that reach the target fineness enter the next process through the outlet without being ground even finer. This helps to improve the product recovery rate and avoids over-grinding.

[0033] The working principle of this utility model is as follows: First, the device can be stably fixed to the ground by the support frame 2 and the support base 3. Then, the grinding medium hopper 4 allows the grinding medium to enter the interior of the grinding assembly 5. Next, the feeding system 55 allows the material to enter the inner cavity of the grinding cylinder 51. Then, the motor 53 drives the rotating shaft 56 to drive several grinding rotors 58 to rotate on the inner wall of the liner 59. Thus, with the cooperation of several stator rings 510, the particles are ground in sections. The central part is a low-intensity grinding zone, and the outer part is a high-intensity grinding zone. In use, the particles can be separated into fine particles and coarse particles by centrifugal force. By the action of centrifugal force, the fine particles are pushed into the high-intensity grinding zone, while the fine particles move upward on the inner side of the vortex near the rotating shaft 56 and are discharged from the top outlet.
