[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] A material roller assembly of a mixing mill, such as Figure 1-Figure 5 As shown, the material roller assembly is installed on the main body 1 of the mixing mill. The material roller assembly includes two rollers 3. The rollers 3 are hollow structures. The inner walls of the rollers 3 are fixed with limit rods 31 distributed in an array. The rollers 3 are fixed with retaining rings 37 distributed in an array. The inner rings of the retaining rings 37 are provided with positioning grooves 38 distributed in an array. Sealing plates 32 are fixed at both ends of the rollers 3, and bearings 33 are rotatably provided in the sealing plates 32.

[0027] A shaft 34 is fixedly connected to the bearing 33, and an array of round blocks 35 are fixed on the shaft 34. An array of protrusions 36 are fixed on the outside of the round blocks 35. The protrusions 36 are connected to the positioning grooves 38, so that the round blocks 35 are fixedly connected to the retaining ring 37. A ceramic heating plate 4 is fixed between the limit rods 31. The ceramic heating plate 4 is made of arc-shaped ceramic material and the model is: HTL-400EX.

[0028] The rolling roller 3 is made of alloy tool steel and is used to conduct the heat of the ceramic heating plate 4 to heat the raw material of the sealing ring. The raw material of the sealing ring is refined. The shaft 34 is a hollow structure. A power supply line is installed in the shaft 34. The power supply line is connected to the ceramic heating plate 4 for power supply. The ceramic heating plate 4 is installed in the rolling roller 3 and fixedly installed between two adjacent limit rods 31. Then, two round blocks 35 are used to limit the inner side of the ceramic heating plate 4 to lock the ceramic heating plate 4.

[0029] A gear 39 is fixedly provided at one end of the roller 3. The two rollers 3 are meshed with each other through the two gears 39, so that the two rollers 3 rotate synchronously to perform the refining operation. A mounting plate 5 is sleeved on the other end of the roller 3. The mounting plate 5 is fixedly mounted on the main body 1 of the refining mill, and collars 51 are fixedly provided at both ends of the mounting plate 5. The collar 51 is rotatably connected to the roller 3. A scraper 52 is fixedly connected to one side of the collar 51. The scraper 52 is in contact with the roller 3 to scrape off excess material on the roller 3.

[0030] Here’s how it works:

[0031] By adopting a hollow structure inside the roller 3, the mass of the roller 3 is reduced and the driving consumption of the mill is reduced. In addition, a number of ceramic heating plates 4 are installed in the roller 3. The ceramic heating plates 4 generate heat and conduct it efficiently to the roller 3. The surface sealing ring material of the roller 3 can be cut, and the roller 3 is processed through the shaft 34.

[0032] The round block 35 on the shaft 34 reinforces the ceramic heating plate 4 and fixes the ceramic heating plate 4. In actual use, the ceramic heating plate 4 can heat the roller 3 evenly. If a ceramic heating plate 4 is damaged, when replacing the ceramic heating plate 4, the shaft 34 is removed and the corresponding ceramic heating plate 4 is replaced, thereby reducing maintenance costs and the daily maintenance cost of the roller 3. The position of the roller 3 is stabilized by the mounting plate 5 to ensure that the roller 3 is stably placed on the mill body 1 for sealing ring refining operations.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
