Description

Technical Field

[0001] This utility model relates to the field of aluminum ash processing equipment, specifically to an integrated equipment for crushing and grinding rotary kiln calcined clinker. Background Technology

[0002] Rotary kiln calcined clinker is a common industrial raw material with wide applications in aluminum ash treatment. The clinker after rotary kiln calcination typically requires further processing, such as crushing and ball milling, to meet the needs of subsequent production processes. Currently, the processing of rotary kiln calcined clinker mainly employs a multi-step, multi-equipment approach: first, the clinker is crushed, and then it is conveyed to a ball mill for grinding.

[0003] However, existing technologies have the following problems: First, the aluminum ash clinker calcined in rotary kilns has different particle sizes, and directly grinding it in a ball mill will lead to uneven grinding, affecting subsequent use. Second, existing crushing and ball milling equipment are usually separate, requiring additional conveying equipment to feed the crushed material into the ball mill, increasing equipment investment and floor space. Third, existing equipment has limited capacity for classifying materials of different particle sizes, and cannot effectively return large particles for re-crushing, resulting in low processing efficiency.

[0004] Therefore, there is an urgent need for equipment that can organically combine the crushing and ball milling processes of rotary kiln calcined clinker to achieve integrated processing, so as to improve production efficiency and ensure uniform grinding. Utility Model Content

[0005] To address the technical problem that uneven grinding of aluminum ash clinker calcined in rotary kilns, due to varying particle sizes, occurs when directly ground in a ball mill, thus affecting subsequent performance, an integrated crushing and ball milling device for rotary kiln calcined clinker is provided. This device achieves uniform particle size in the aluminum ash clinker, improving grinding efficiency and product quality.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A rotary kiln calcined clinker crushing and ball milling integrated equipment is provided, including a base. A first support is fixedly installed at the middle of the upper end of the base. Second supports are fixedly installed on the front and rear sides of the first support at the upper end of the base. A third support is fixedly installed on the right side of the first support at the upper end of the base. A support plate is fixedly installed on the inner side of the first support at the upper end. A crushing mechanism is provided at the upper end of the inner side of the first support. A screening mechanism is provided at the lower end of the crushing mechanism at the middle of the inner side of the first support. A spiral conveying pipe is provided at the lower end of the screening mechanism on the support plate. A ball mill is provided at the discharge end of the spiral conveying pipe. A return spiral clinker pipe fixed on the third support is provided on one side of the screening mechanism.

[0007] Furthermore, a front support plate is fixedly connected to the outer side of the upper end of the first bracket, a rear support plate is fixedly connected to the outer side of the upper end of the first bracket, a first motor is fixedly mounted on the front support plate, and a second motor is fixedly mounted on the rear support plate.

[0008] Furthermore, the crushing mechanism includes a crushing box, with a feeding port at the upper end of the crushing box and a crushed material discharge port at the lower end of the crushing box. A first crushing roller and a second crushing roller are arranged in parallel inside the crushing box.

[0009] Furthermore, the output end of the first motor is connected to the second crushing roller, and the output end of the second motor is connected to the first crushing roller.

[0010] Furthermore, the screening mechanism includes a screening box, an outlet at the front end of the screening box, a screening plate inclinedly arranged inside the screening box, a return port extending to the outside of the screening box, buffer springs on the left and right sides of the screening box, a vibration motor fixedly arranged at the rear end of the screening box, and a qualified material outlet at the lower end of the screening box.

[0011] Furthermore, the qualified material outlet is located above the feed end of the spiral conveyor pipe, and the return material outlet is located above the feed end of the return spiral feed pipe.

[0012] The beneficial effects of this utility model are as follows:

[0013] By adding a crushing and screening mechanism before the ball mill and setting up a return material mechanism, the particle size of the aluminum ash clinker entering the ball mill is made uniform. The crushing mechanism initially crushes the aluminum ash clinker calcined in the rotary kiln. The crushed clinker enters the screening mechanism for screening. The screening mechanism uses a vibrating motor to drive the screen plate to vibrate and screen the crushed clinker. Clinker with qualified particle size enters the spiral conveyor pipe through the qualified material outlet and is finally sent to the ball mill for grinding; while clinker with unqualified particle size enters the return spiral conveyor pipe through the return material outlet and returns to the crushing mechanism for re-crushing. This design solves the problem of uneven grinding caused by direct grinding, improves the grinding effect and product quality, and is beneficial for subsequent use. At the same time, the entire equipment structure is integrated, the workflow is continuous, improves production efficiency, and reduces the intensity of manual operation. Attached Figure Description

Detailed Implementation

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] like Figure 1 As shown, an integrated ball mill and crushing equipment for rotary kiln calcined clinker includes a base 1. A first support 9 is fixedly installed at the middle of the upper end of the base 1. Second supports 8 are fixedly installed on the front and rear sides of the first support 9 at the upper end of the base 1. A third support 2 is fixedly installed on the right side of the first support 9 at the upper end of the base 1. A support plate 7 is fixedly installed on the inner side of the first support 9 at the upper end of the base 1. A crushing mechanism 4 is provided at the upper end of the inner side of the first support 9. A screening mechanism 12 is provided at the lower end of the crushing mechanism 4 at the middle of the inner side of the first support 9. A spiral conveying pipe 5 is provided at the lower end of the screening mechanism 12 on the support plate 7. A ball mill 6 is provided at the discharge end of the spiral conveying pipe 5. A return spiral conveying pipe 3 is fixed on the third support 2 on one side of the screening mechanism 12.

[0023] like Figure 2As shown, a front support plate 10 is fixedly connected to the outer side of the upper end of the first support 9, and a rear support plate 11 is fixedly connected to the outer side of the upper end of the first support 9. A first motor 405 is fixedly mounted on the front support plate 10, and a second motor 403 is fixedly mounted on the rear support plate 11. The front support plate 10 and the rear support plate 11 are located on the front and rear sides of the first support 9, respectively, providing a mounting platform for the motor of the crushing mechanism 4.

[0024] like Figure 2 and Figure 3 As shown, the crushing mechanism 4 includes a crushing chamber 401. A feeding port 402 is located at the upper end of the crushing chamber 401, and a crushed material discharge port 404 is located at the lower end of the crushing chamber 401. A first crushing roller 406 and a second crushing roller 407 are arranged parallel to each other inside the crushing chamber 401. The output end of a first motor 405 is connected to the second crushing roller 407, and the output end of a second motor 403 is connected to the first crushing roller 406. The two crushing rollers rotate relative to each other, achieving the crushing effect on the clinker calcined in the rotary kiln. The clinker fed through the feeding port 402 is crushed between the first crushing roller 406 and the second crushing roller 407. The crushed material falls into the screening mechanism 12 below through the crushed material discharge port 404. The two motors drive the two crushing rollers respectively, improving the crushing efficiency.

[0025] like Figure 4 As shown, the screening mechanism 12 includes a screening box 121. An outlet 122 is provided at the front end of the screening box 121. A screening plate 127 is inclinedly arranged inside the screening box 121. The screening plate 127 extends to the outside of the screening box 121 and has a return port 123. Buffer springs 125 are provided on the left and right sides of the screening box 121. A vibration motor 126 is fixedly installed at the rear end of the screening box 121. A qualified material outlet 124 is provided at the lower end of the screening box 121. The screening box 121 is connected to the support structure via the buffer springs 125. When the vibration motor 126 operates, it vibrates, causing the screening plate 127 to vibrate, thereby screening the falling material. The smaller particles in the material fall through the sieve holes on the sieve plate 127 and enter the spiral conveyor pipe 5 through the qualified material outlet 124; while the larger particles slide along the inclined sieve plate 127 to the return port 123, enter the return spiral conveyor pipe 3, and return to the crushing mechanism 4 for further crushing.

[0026] like Figure 5 As shown, the qualified material outlet 124 is located above the feed end of the spiral conveyor pipe 5, and the return material outlet 123 is located above the feed end of the return spiral feed pipe 3. This arrangement ensures smooth material flow. The qualified material after screening falls directly into the spiral conveyor pipe 5 and is transported to the ball mill 6 for further ball milling. The unqualified material is returned to the crushing mechanism 4 through the return spiral conveyor pipe 3 for further crushing, forming a closed-loop processing system.

[0027] The working principle of this rotary kiln calcined clinker crushing and ball milling integrated equipment is as follows: the clinker calcined from the rotary kiln enters the crushing mechanism 4 through the feeding port 402, where it is initially crushed by the action of the first crushing roller 406 and the second crushing roller 407. The crushed material falls into the screening mechanism 12 through the crushed material outlet 404. In the screening mechanism 12, the vibrating motor 126 drives the screening box 121 to vibrate, and the material is screened on the screen plate 127. The material that meets the particle size requirements falls into the screw conveyor pipe 5 through the qualified material outlet 124 and is transported to the ball mill 6 for further ball milling; the material that does not meet the particle size requirements enters the return screw conveyor pipe 3 through the return material outlet 123 and returns to the crushing mechanism 4 for further crushing until the required particle size is achieved.

[0028] This integrated equipment combines crushing and ball milling processes, enabling continuous processing of rotary kiln calcined clinker, improving production efficiency, and reducing material transfer losses in intermediate stages. Simultaneously, the design of the screening mechanism and return system ensures uniformity of material particle size, improving the efficiency of subsequent ball milling processes and product quality. The overall structure is compact, occupies a small area, and the connections between components are smooth, forming a complete production line.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
