Technical Field

[0001] This utility model relates to the field of cement processing technology, specifically to a ball mill for cement production and processing. Background Technology

[0002] A ball mill is a commonly used grinding or milling device. It consists of a horizontally rotating, slowly moving cylinder filled with spherical grinding media (steel balls, zirconia balls, alumina balls, pebbles, or ceramic balls). Based on the discharge method, ball mills are classified as overflow type, grate type, and peripheral type. Overflow type ball mills are typically used for grinding in cement production.

[0003] For example, utility model patent CN221433282U discloses a cement production ball mill, including a rotating cylinder with a drive motor and a reducer on one side; an inner liner plate laid on the inner wall of the rotating cylinder; a fixing assembly disposed on the outer wall of the rotating cylinder in a circular array, the fixing assembly including a fixing plate and a fixing rod; and a limiting unit disposed between the outer wall of the fixing rod and the outer wall of the rotating cylinder, the limiting unit including a sleeve and a stud. When this device is in use, the cement production raw materials are prone to agglomeration due to the influence of water vapor in the air. Agglomerated raw materials are prone to clogging the feed inlet of the ball mill, affecting the feed speed of the ball mill, and thus reducing the processing efficiency of the ball mill. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a ball mill for cement production and processing, which solves the problem that when the cement production raw materials are used, they are easily agglomerated by water vapor in the air. The agglomerated raw materials are easy to block the feed inlet of the ball mill, affecting the feed speed of the ball mill and thus reducing the processing efficiency of the ball mill.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ball mill for cement production and processing, comprising a pair of support plates, a ball mill body rotatably disposed between the pair of support plates, a mounting frame disposed on one side of the ball mill body, a pre-crushing chamber disposed on the mounting frame, a first motor bracket disposed on the pre-crushing chamber, a first motor disposed on the upper wall of the first motor bracket, a crushing roller disposed on the drive end of the first motor, the crushing roller rotatably disposed within the pre-crushing chamber, a feed hopper disposed on the pre-crushing chamber, a first pressure block disposed on the feed hopper, a mounting base disposed on the pre-crushing chamber, a multi-stage electric hydraulic cylinder disposed on the mounting base, a second pressure block disposed on the telescopic end of the multi-stage electric hydraulic cylinder, the second pressure block movably disposed on the feed hopper, and a second discharge port disposed between the pre-crushing chamber and the ball mill body.

[0006] Preferably, a second motor support is provided below the ball mill body, a second motor is provided on the upper wall of the second motor support, a gear is provided on the drive end of the second motor, and an annular rack is provided on the ball mill body, with the gear and the annular rack meshing together.

[0007] Preferably, the ball mill body is provided with a first discharge port, a second support frame is provided on the first discharge port, and a screen is provided on the second support frame.

[0008] Preferably, a hopper is provided above the pre-crushing hopper, the outlet of the hopper is connected to the feed hopper, and a first support frame is provided on the hopper.

[0009] Preferably, a collection box is provided below the screen.

[0010] Beneficial effects

[0011] The ball mill for cement production and processing provided by this utility model has the following beneficial effects:

[0012] This design uses a multi-stage electric hydraulic cylinder to extend and retract, thereby moving the second pressure block and crushing the raw materials in the feed hopper. This prevents the raw materials from clumping and clogging the feed hopper, thus improving the production efficiency of the ball mill.

[0013] This design drives the first motor to rotate, which in turn drives the crushing roller to rotate, thus pre-crushing the agglomerated raw materials in the pre-crushing chamber. This reduces the volume of the agglomerated cement production raw materials, preventing the cement production raw materials from clogging the feed inlet of the ball mill body and slowing down the raw material feeding speed, thereby improving the processing efficiency of the ball mill.

[0014] This design drives a second motor to rotate, which in turn drives a gear to rotate, controlling the movement of a ring rack. This causes the ball mill body to rotate, which in turn drives the first discharge port to rotate, causing the second support frame to rotate, and consequently the screen to rotate. This allows for the screening of cement production raw materials falling into the screen, preventing larger particles from entering the collection box and affecting the quality of the cement production raw materials, thereby improving the processing efficiency of the ball mill.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a ball mill for cement production and processing, including a pair of support plates 9, a ball mill body 14 rotatably disposed between the pair of support plates 9, a mounting frame 4 disposed on one side of the ball mill body 14, a pre-crushing chamber 20 disposed on the mounting frame 4, a first motor bracket 3 disposed on the pre-crushing chamber 20, a first motor 2 disposed on the upper wall of the first motor bracket 3, a crushing roller 22 disposed on the drive end of the first motor 2, the crushing roller 22 rotatably disposed in the pre-crushing chamber 20, a feed hopper 16 disposed on the pre-crushing chamber 20, a first pressure block 15 disposed on the feed hopper 16, a mounting base 19 disposed on the pre-crushing chamber 20, a multi-stage electric hydraulic cylinder 18 disposed on the mounting base 19, a second pressure block 17 disposed on the telescopic end of the multi-stage electric hydraulic cylinder 18, the second pressure block 17 movably disposed on the feed hopper 16, and a second discharge port 21 disposed between the pre-crushing chamber 20 and the ball mill body 14;

[0021] The multi-stage electric hydraulic cylinder 18 is driven to extend and retract, which in turn moves the second pressure block 17. This can crush the raw materials in the feed hopper 16, preventing the raw materials from clumping and blocking the feed hopper 16, thereby improving the production efficiency of the ball mill.

[0022] The first motor 2 is driven to rotate, which in turn drives the crushing roller 22 to rotate, and pre-crushes the agglomerated raw materials in the pre-crushing chamber 20. This reduces the volume of the agglomerated cement production raw materials, prevents the cement production raw materials from clogging the feed inlet of the ball mill body 14, and thus slows down the raw material feeding speed, thereby improving the processing efficiency of the ball mill.

[0023] The crushing roller 22 is equipped with spiral blades for conveying cement raw materials in the pre-crushing bin 20.

[0024] In this embodiment, a second motor support 7 is provided below the ball mill body 14, a second motor 6 is provided on the upper wall of the second motor support 7, a gear 8 is provided on the drive end of the second motor 6, and an annular rack 13 is provided on the ball mill body 14, with the gear 8 and the annular rack 13 meshing with each other.

[0025] The second motor 6 is driven to rotate, which in turn drives the gear 8 to rotate, controls the movement of the ring rack 13, and thus causes the ball mill body 14 to rotate, which can grind the cement raw materials inside the ball mill body 14.

[0026] In this embodiment, the ball mill body 14 is provided with a first discharge port 11, a second support frame 12 is provided on the first discharge port 11, and a screen 23 is provided on the second support frame 12.

[0027] The first discharge port 11 is equipped with anti-spiral blades, which can send the overflowed coarse particles and grinding balls back into the grinding machine body 14;

[0028] The second motor 6 is driven to rotate, which in turn drives the gear 8 to rotate, controls the movement of the ring rack 13, causes the ball mill body 14 to rotate, drives the first discharge port 11 to rotate, causes the second support frame 12 to rotate, and then causes the screen 23 to rotate. This allows the cement production raw materials falling into the screen 23 to be screened, which can prevent large cement production raw materials from entering the collection box 10 and affecting the quality of the cement production raw materials, thereby improving the processing effect of the ball mill.

[0029] In this embodiment, a hopper 1 is provided above the pre-crushing hopper 20, the outlet of the hopper 1 is connected to the feed hopper 16, and a first support frame 5 is provided on the hopper 1.

[0030] Silo 1 is used to store raw materials for cement production.

[0031] In this embodiment, a collection box 10 is further provided below the screen 23;

[0032] An opening is provided at the top of the collection box 10 for collecting cement production raw materials after screening by the screen 23.

[0033] Example: When using the ball mill, the operator stores the cement production raw materials in the hopper 1. The cement production raw materials in the hopper 1 enter the pre-crushing chamber 20 through the feed hopper 16. The multi-stage electric hydraulic cylinder 18 extends and retracts, driving the second pressure block 17 to move, thus crushing the production raw materials in the feed hopper 16. This prevents the production raw materials from clumping and clogging the feed hopper 16, thereby improving the production efficiency of the ball mill. The first motor 2 rotates, driving the crushing roller 22 to rotate, pre-crushing the clumped raw materials in the pre-crushing chamber 20, reducing the volume of the clumped cement production raw materials, and preventing the cement production raw materials from clogging the feed inlet of the ball mill body 14, which would slow down the raw material feeding speed, thereby improving the processing efficiency of the ball mill. The water in the pre-crushing chamber 20... The slurry raw material enters the ball mill body 14 through the second discharge port 21, driving the second motor 6 to rotate, which in turn drives the gear 8 to rotate, controlling the movement of the ring rack 13, thereby causing the ball mill body 14 to rotate. This allows for the grinding of the cement raw material inside the ball mill body 14. The cement raw material overflows into the screen 23. The rotation of the ball mill body 14 drives the first discharge port 11 to rotate, causing the second support frame 12 to rotate, which in turn causes the screen 23 to rotate. This allows for the screening of the cement raw material falling into the screen 23, preventing larger cement raw materials from entering the collection box 10 and affecting the quality of the cement raw materials, thus improving the processing effect of the ball mill. The collection box 10 is used to collect the cement raw materials after screening by the screen 23.

[0034] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
