[0002] Vertical mill is a grinding equipment that integrates fine crushing, drying, grinding, powder selection and conveying. It is widely used in the grinding and ultra-fine grinding of various solid materials in cement, building materials, electric power, metallurgy, chemical industry, non-metallic minerals and other industries. It is widely used in metallurgy, building materials, chemical industry, mining and other fields.

[0003] After searching, the utility model with Chinese patent publication number CN218609667U discloses an ultra-fine vertical mill that is easy to adjust the speed, including a support frame, a hopper is rotatably provided on the top of the support frame, the top of the hopper is open, a support device is provided on the outside of the hopper, and a grinding head extending into the interior of the hopper is provided at the output end of the support device, and the grinding head is connected to an independent drive motor.

[0004] During the use of the vertical mill, large pieces of material are first broken into small pieces by the ore crusher.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] The utility model provides a technical solution: Figure 2 and Figure 3As shown, in this embodiment, an ultrafine vertical mill provided with an automatic crushing and feeding structure includes a processing box 1, characterized in that: a crushing assembly 5 is installed inside the processing box 1, and the crushing assembly 5 includes two crushing rollers 1 501 and two crushing rollers 2 502 rotatably connected to the inner walls at both ends of the processing box 1, the two crushing rollers 1 501 and the two crushing rollers 2 502 are adapted to each other, and the outer wall of one end of the processing box 1 is rotatably connected to two gears 1 504 and two gears 2 505, the two gears 1 504 are coaxially fixed to the two crushing rollers 1 501 respectively, and the two gears 2 505 are coaxially fixed to the two crushing rollers 2 502 respectively, and the same partition 503 is fixedly connected to the middle of the inner walls at both ends of the processing box 1, and the two crushing rollers 1 501 and the two crushing rollers 2 502 are located on one side of the partition 503.

[0026] A motor 507 is fixedly mounted on the outer wall of one end of the processing box 1 , and a gear 3 506 is coaxially fixed to the rotating shaft of the motor 507 , wherein the gear 2 505 and the gear 3 506 are both engaged with the gear 3 506 .

[0027] The distance between the two crushing rollers 501 is smaller than the distance between the two crushing rollers 502, so that graded crushing can be achieved, which is beneficial to improving crushing efficiency.

[0028] The material that slides down from the screen plate 603 first falls between the two crushing rollers 501, and at the same time, the motor 507 outside the processing box 1 is started, and the motor 507 drives the gear three 506 to rotate. The gear three 506 drives one gear one 504 and the gear two 505 to rotate counterclockwise through engagement, and then the other gear one 504 and the gear two 505 are also driven to rotate. At this time, the two crushing rollers 1 501 and the crushing roller 2 502 will start to run. Under the action of the two crushing rollers 1 501, the material gradually becomes a slightly smaller individual, and then falls between the two crushing rollers 2 502, thereby being transformed into a qualified individual. With the cooperation of the two, the effect of improving the crushing efficiency can be achieved.

[0029] like Figure 2 and Figure 4 As shown, a screening assembly 6 is installed inside the processing box 1, and the screening assembly 6 includes an extension plate 601 fixedly connected to the inner wall of one side of the processing box 1, and multiple springs 602 are fixedly connected to the extension plate 601 and the top outer wall of the partition 503. The top end of the multiple springs 602 is fixedly connected to the same screen plate 603, and the screen plate 603 is arranged at an angle, and one end of the screen plate 603 is located in the middle position of the two crushing rollers 501.

[0030] A vibrator 604 is fixedly installed in the middle of the bottom outer wall of the sieve plate 603.

[0031] Under the action of the screen plate 603, larger individuals of the material will be intercepted and then slide to one side along the slope of the screen plate 603. At the same time, the vibrator 604 at the bottom of the screen plate 603 is started. Since the bottom of the screen plate 603 is connected by a spring 602, it can be guaranteed to move up and down. The vibrator 604 can drive the screen plate 603 to move up and down quickly, thereby ensuring that the screening efficiency can be improved and avoiding excessive accumulation of materials affecting the crushing efficiency.

[0032] like Figure 1 and Figure 2 As shown, a guide hopper 4 is fixedly connected to the top outer wall of the processing box 1. The guide hopper 4 is located on one side of the top of the screen plate 603 to prevent the material from falling to the other side due to insufficient screening time.

[0033] like Figure 1 As shown, a connecting frame 2 is fixedly connected to the outer walls of both sides of the processing box 1, and the same vertical mill body 3 is fixedly installed at one end of the bottom of the two connecting frames 2. The materials falling from the bottom opening of the processing box 1 will enter the interior of the vertical mill body 3, and then these materials can complete the grinding work.

[0034] The utility model provides an ultra-fine vertical mill with an automatic crushing and feeding structure. The specific working principle is as follows:

[0035] When the device is working, the material is put into the guide hopper 4, and the material will fall from the opening at the bottom of the guide hopper 4 to the top of the screen plate 603. Under the action of the screen plate 603, the larger individual materials will be intercepted and then slide to one side along the slope of the screen plate 603. At the same time, the vibrator 604 at the bottom of the screen plate 603 is started. Since the bottom of the screen plate 603 is connected by a spring 602, it can be ensured that it can move up and down. The vibrator 604 can drive the screen plate 603 to move up and down quickly, thereby ensuring that the screening efficiency can be improved, and it can avoid that too much material accumulation affects the crushing efficiency. The material sliding off the screen plate 603 falls first. The material moves between the two crushing rollers 501 and the motor 507 outside the processing box 1 is started at the same time. The motor 507 drives the gear three 506 to rotate. The gear three 506 drives the gear one 504 and the gear two 505 to rotate counterclockwise through engagement, and then the other gear one 504 and the gear two 505 are also driven to rotate. At this time, the two crushing rollers 1 501 and the crushing roller two 502 will start to run. Under the action of the two crushing rollers 1 501, the material gradually becomes slightly smaller individuals, and then falls between the two crushing rollers 2 502, thereby being transformed into qualified individuals. With the cooperation of the two, the effect of improving the crushing efficiency can be achieved.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
