Description

Technical Field

[0001] This utility model relates to the technical field of grinding mills, and more particularly to an adjustable Raymond grinding mill. Background Technology

[0002] Raymond mill is an important grinding equipment widely used in industries such as mining, metallurgy, chemical engineering, and building materials. It is mainly used for grinding materials of medium hardness, such as limestone, calcite, marble, and other non-metallic ores.

[0003] Raymond mills primarily rely on the relative motion between grinding rollers and grinding rings to grind materials. During operation, materials are fed into the grinding zone formed between the rollers and rings, where they are gradually broken down into fine particles, ultimately achieving the desired fineness. However, in traditional Raymond mill designs, the distance between the rollers and rings is typically fixed, limiting the flexibility of adjusting the output fineness. Since different applications have varying requirements for powder coarseness, a fixed distance setting is insufficient to meet diverse production needs. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose an adjustable Raymond mill that can flexibly adjust the distance between the grinding roller and the grinding ring, thereby grinding powders of different fineness to meet diverse production needs.

The multiple grinding rollers are circumferentially distributed on the outer side of the protective shell. The inner wall of the housing is provided with grinding rings that cooperate with the grinding rollers. The shovel mechanism is connected to the rotating mechanism and is located above the partition.

[0007] The adjustable Raymond mill of this invention can flexibly adjust the distance between the grinding roller and the grinding ring, thereby grinding powders of different fineness to meet diverse production needs.

[0008] In addition, the adjustable Raymond mill proposed in the application may also have the following additional technical features:

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The adjustable Raymond mill of this utility model is described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the adjustable Raymond mill of this utility model embodiment may include a housing 10, a rotating mechanism 20, a position adjusting mechanism 40 and a shovel mechanism 70. The inner wall of the housing 10 is connected to a partition 11, and a feed hopper 12 is provided on one side of the housing 10. The rotating mechanism 20 is provided on the bottom wall of the housing 10 and is connected to a protective shell 30 through the partition 11.

[0023] It should be noted that an observation window may be provided on one side of the housing 10 for observing the adjustment of the grinding roller 61 inside the housing 10.

[0024] The position adjustment mechanism 40 is located inside the protective shell 30, and the position adjustment mechanism 40 is connected to multiple mounting plates 50. The mounting plates 50 pass through the side wall of the protective shell 30, and the bottom surface of the mounting plates 50 is rotatably equipped with grinding rollers 61. Multiple grinding rollers 61 are circumferentially distributed on the outside of the protective shell 30. The inner wall of the shell 10 is provided with a grinding ring 62 that cooperates with the grinding rollers 61. The feed hopper 12 is located above the grinding ring 62. The shovel mechanism 70 is connected to the rotating mechanism 20 and is located above the partition plate 11.

[0025] Specifically, the operator activates the position adjustment mechanism 40 to adjust the positions of multiple mounting plates 50, thereby adjusting the distance between multiple grinding rollers 61 and grinding ring 62 to control the fineness of the ground product. Then, the operator activates the rotation mechanism 20 to drive the protective shell 30 and the scraper mechanism 70 to rotate. The protective shell 30 drives multiple grinding rollers 61 to revolve. Subsequently, the material to be ground is placed into the feed hopper 12, and the material falls onto the partition plate 11. The scraper mechanism 70 scoops up the material while rotating and adds it between the grinding rollers 61 and grinding ring 62. The grinding rollers 61 and grinding ring 62 work together to grind the material. The scraper mechanism 70 can disperse the material entering the grinding area to ensure that the material is evenly distributed between the grinding rollers 61 and grinding ring 62.

[0026] The adjustable Raymond mill of this utility model can flexibly adjust the distance between the grinding roller and the grinding ring, thereby grinding powders of different fineness to meet diverse production needs.

[0027] In one embodiment of this utility model, such as Figure 1 As shown, the rotating mechanism 20 may include a rotating driver 21 and a rotating shaft 22. The rotating driver 21 is connected to the bottom wall of the housing 10, the rotating shaft 22 is connected to the output end of the rotating driver 21, the rotating shaft 22 passes through the partition 11 and is connected to the protective shell 30, and the rotating shaft 22 is rotatably connected to the partition 11.

[0028] It should be noted that the rotary driver 21 described in this embodiment can be a motor. The rotary driver 21 can drive the rotating shaft 22 to rotate, thereby driving the protective shell 30 to rotate, and then driving the multiple grinding rollers 61 to move circumferentially.

[0029] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the position adjustment mechanism 40 may include a fixed plate 41, a drive component 42, a turntable 43, multiple moving rods 44, and multiple sliding grooves 45.

[0030] The fixed plate 41 is connected to the inner wall of the protective shell 30. The driving component 42 is set on the bottom wall of the protective shell 30. The output shaft of the driving component 42 passes through the fixed plate 41 and is connected to the turntable 43. The turntable 43 is provided with multiple arc-shaped holes 431 in the circumferential direction. Multiple moving rods 44 are respectively located in the multiple arc-shaped holes 431. Multiple mounting plates 50 are respectively connected to the multiple moving rods 44. Multiple sliding grooves 45 are arranged in the circumferential direction on the fixed plate 41. The mounting plates 50 and the sliding grooves 45 are slidably connected.

[0031] It should be noted that the driving component 42 described in this embodiment can be a motor. The two ends of the slide groove 45 are not closed, but open. The driving component 42 can drive the turntable 43 to rotate, thereby driving multiple moving rods 44 to move in each arc hole 431, thereby driving the mounting plate 50 to move. During this process, the slide groove 45 provides a guiding effect for the mounting plate 50, so that it moves in a straight line, thereby adjusting the distance between the grinding roller 61 and the grinding ring 62.

[0032] In one embodiment of this utility model, such as Figure 1 As shown, the shovel mechanism 70 may include a shovel disc 71 and a plurality of shovels 72, wherein the shovel disc 71 is fixedly sleeved on the rotating shaft 22, and the plurality of shovels 72 are circumferentially arranged on the outer wall of the shovel disc 71.

[0033] It should be noted that the rotating mechanism 20 can drive the scraper disc 71 to rotate. The scraper 72 can scoop up the material falling into the housing 10 by rotating and add it between the grinding roller 61 and the grinding ring 62. This helps to disperse the material entering the grinding area and ensures that the material can be evenly distributed between the grinding roller 61 and the grinding ring 62.

[0034] In one embodiment of this utility model, such as Figure 1 As shown, a cyclone collector 80 is provided on the top of the housing 10.

[0035] It should be noted that the cyclone collector 80 is used to separate and collect the ground material powder. The centrifugal force generated by the high-speed rotating airflow causes the heavier particulate matter to be separated from the air and collected by the cyclone collector, while the purified air is discharged through the outlet of the cyclone collector 80.

[0036] In summary, the adjustable Raymond mill of this utility model embodiment can flexibly adjust the distance between the grinding roller and the grinding ring, thereby grinding powders of different fineness to meet diverse production needs.
