Description

Technical Field

[0001] This utility model relates to the technical field of low-alkali cement grinding machines, specifically a low-alkali cement grinding machine with multiple grinding effects. Background Technology

[0002] Low-alkali cement grinding mills are mainly used to process cement raw materials and clinker. Through a fine grinding process, the grinding mill can improve the fineness and uniformity of cement, thereby improving the quality of cement. The grinding mill is not only suitable for cement production, but can also be used for grinding other materials, such as concrete and ore, making low-alkali cement grinding mills quite common in use.

[0003] However, most low-alkali cement grinding mills require grinding both raw cement and clinker, and typically use internal grinding rollers for single-pass grinding. This often results in uneven crushing of the raw cement and clinker, leading to poor powder quality and making the grinding process inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a low-alkali cement grinder with multiple grinding effects, so as to solve the problem of poor single-grinding effect of low-alkali cement grinders mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-alkali cement grinder with multiple grinding effects, comprising a grinder body, grinding rollers, a guide plate, a filling port, a discharge port, and a sieve plate. The grinder body is provided with symmetrically distributed grinding rollers inside. The grinding rollers are provided with symmetrically distributed guide plates at one end of the grinder body near the grinding rollers. The top of the grinder body is provided with a filling port. The bottom of the grinder body is provided with a discharge port, which is shaped like a semi-circular groove. The end of the grinding rollers away from the guide plate is provided with a sieve plate.

[0006] Preferably, both sides of the grinding machine body are provided with welded material guide boxes, and the side of the material guide box away from the grinding machine body is provided with a welded feed box.

[0007] Preferably, a first drive motor is installed at the bottom of the feeding box.

[0008] Preferably, the output end of the first drive motor is connected to a screw rod via a coupling, and a feeding groove is provided inside the feeding box on the side near the screw rod.

[0009] Preferably, the end of the feed box away from the first drive motor is provided with a feeding plate connected to the grinding machine body.

[0010] Preferably, a fixing box is provided at the bottom of the sieve plate, and a grinding seat is provided inside the fixing box. The grinding seat is in the shape of a cone.

[0011] Preferably, a second drive motor is installed on the bottom end of the grinding machine body near the discharge port, and the output end of the second drive motor is connected to a rotating rod connected to the grinding seat via a coupling.

[0012] Preferably, a welded fixing frame is provided on one side of the filling port, and a third drive motor is installed on one side of the fixing frame.

[0013] Preferably, the output end of the third drive motor is connected to a rotating rod via a coupling, and the end of the rotating rod away from the third drive motor is connected to a bearing inside the filling port.

[0014] Preferably, the surface of the rotating rod is provided with uniformly distributed mixing rods.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This low-alkali cement grinder with multiple grinding effects can transport materials into the feed box through the feed box, and then start the first drive motor so that the materials can be refilled through the feed plate, so that the low-alkali cement grinder can have a better multiple grinding effect when in use. By starting the third drive motor, the rotating rod connected to the output end can rotate the mixing rod set on the surface. With the rotation of the mixing rod, the low-alkali cement grinder can avoid clogging caused by excessive filling when in use, so that the low-alkali cement grinder can have a better anti-clogging effect when in use.

[0016] 1. This low-alkali cement grinder with multiple grinding effects addresses the common problem that single-cycle grinding often results in uneven crushing, making it inconvenient to use. The grinder first grinds the cement raw material or clinker using grinding rollers inside the grinder body. The ground material is then screened through a sieve at the bottom, and any incompletely crushed material is discharged into a guide box. From there, the material is fed into a feed box. The first drive motor is then activated, rotating a screw rod connected to the output end. This screw rod quickly guides the material, allowing it to be discharged back into the grinder body along a top-mounted discharge plate. This repeated grinding within the grinder body prevents incomplete crushing and provides a superior multi-grinding effect.

[0017] 2. This low-alkali cement grinder with multiple grinding effects is prone to clogging when filled too quickly, making it inconvenient to use. By starting the third drive motor, the grinder can rotate the rotating rod connected to its output end. This rotation of the rotating rod, in turn, rotates the connected mixing rod, allowing the mixing rod to rotate inside the filling port. This prevents clogging caused by excessively rapid filling, thus providing a better anti-clogging effect during operation. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-3This utility model provides a technical solution: a low-alkali cement grinder with multiple grinding effects, comprising a grinder body 1, grinding rollers 2, guide plates 3, filling port 4, discharge port 5, and sieve plate 6. The grinder body 1 has symmetrically distributed grinding rollers 2 inside. The guide plates 3 are symmetrically distributed at one end of the grinder body 1 near the grinding rollers 2. The filling port 4 is located at the top of the grinder body 1, and the discharge port 5 is located at the bottom of the grinder body 1. The discharge port 5 is semi-circular in shape. The sieve plate 6 is located at the end of the grinding rollers 2 away from the guide plates 3. The two sides of the grinder body 1... Each side is provided with a welded guide box 7. The side of the guide box 7 away from the grinding machine body 1 is provided with a welded feed box 8. The bottom end of the feed box 8 is equipped with a first drive motor 9. The output end of the first drive motor 9 is connected to a screw rod 10 through a coupling. The feed box 8 has a feed groove 11 on the side near the screw rod 10. The end of the feed box 8 away from the first drive motor 9 is provided with a feed plate 12 connected to the grinding machine body 1. The bottom end of the screen plate 6 is provided with a fixing box 13. The grinding seat 14 is cone-shaped inside the fixing box 13.

[0025] In practice,

[0026] See Figures 1-3 It is known that when a low-alkali cement grinder is in use, uneven crushing is easily produced in a single grinding cycle, making the grinder inconvenient to use. To address this, the grinding rollers 2 inside the grinder body 1 first grind the cement raw material or clinker, allowing the ground material to be screened through the sieve plate 6 at the bottom. The incompletely crushed material is then discharged along the sieve plate 6 into the guide box 7, which then discharges the material into the feed box 8. Finally, the first drive motor 9 is started, causing it to rotate the screw rod 10 connected to the output end, enabling the screw rod 10 to rapidly grind the discharged material. The material is guided to be discharged back into the grinding mill body 1 along the top feed plate 12, allowing the material to be repeatedly ground inside the grinding mill body 1, avoiding incomplete crushing. Furthermore, a grinding seat 14 and a fixed box 13 are provided at the bottom of the screen plate 6, which can be started by the second drive motor 15. The second drive motor 15 can rotate the rotating rod 16 connected to the output end, thereby rotating the connected grinding seat 14. As a result, the grinding seat 14 can work with the fixed box 13 to grind the falling material again, so that the low-alkali cement grinding mill can have a better multiple grinding effect when in use.

[0027] A second drive motor 15 is installed on the bottom end of the grinding machine body 1 near the discharge port 5. The output end of the second drive motor 15 is connected to a rotating rod 16 connected to the grinding base 14 via a coupling. A fixed frame 17 is welded to one side of the filling port 4. A third drive motor 18 is installed on one side of the fixed frame 17. The output end of the third drive motor 18 is connected to a rotating rod 19 via a coupling. The end of the rotating rod 19 away from the third drive motor 18 is connected to the inside of the filling port 4 with a bearing. The surface of the rotating rod 19 is provided with uniformly distributed mixing rods 20.

[0028] In practice,

[0029] See Figure 1 , Figure 2 and Figure 4 It is known that when a low-alkali cement grinder is in use, it is often clogged due to excessively rapid filling, making it inconvenient to use. This can be addressed by starting the third drive motor 18, which rotates the rotating rod 19 connected to the output end. As a result, the rotating rod 19 rotates, it rotates the connected mixing rod 20, allowing the mixing rod 20 to rotate inside the filling port 4. This prevents the low-alkali cement grinder from clogging due to excessively rapid filling, thus providing a better anti-clogging effect during use.

[0030] In summary, the low-alkali cement grinder is mainly used for processing cement raw materials and clinker. Through a fine grinding process, the grinder can improve the fineness and uniformity of cement. The grinding rollers 2 inside the grinder body 1 first grind the cement raw materials or clinker, allowing the ground material to be screened through the sieve plate 6 at the bottom. Subsequently, the incompletely crushed material is discharged into the guide box 7 along the sieve plate 6, and then discharged into the feed box 8 through the guide box 7. The first drive motor 9 can then be started, causing the first drive motor 9 to rotate the screw rod 10 connected to the output end. The screw rod 10 can quickly guide the discharged material, allowing the material to be discharged back into the grinder body 1 along the feed plate 12 at the top. This allows the material to be repeatedly ground inside the grinder body 1, avoiding incomplete crushing. This gives the low-alkali cement grinder a better multi-grinding effect during use. The content not described in detail in this description belongs to the prior art known to those skilled in the art.

[0031] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
