Some embodiments of the application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1-3, an embodiment of the present application provides a heavy metal pulverizer 100, comprising:

A housing 10 including a first grinding chamber 11, a second grinding chamber 12, and a third grinding chamber 13; the first grinding chamber 11 is provided with an opening for feeding, the upper surface of the second grinding chamber 12 is attached to the lower surface of the first grinding chamber 11, and the upper surface of the third grinding chamber 13 is attached to the lower surface of the second grinding chamber 12;

A first crushing layer 20, wherein the first crushing layer 20 is disposed in the first grinding chamber 11, and comprises two main shafts 21 and a plurality of crushing teeth 22, the two main shafts 21 are disposed in parallel, the plurality of crushing teeth 22 are disposed on the two main shafts 21, and the plurality of crushing teeth 22 are engaged with each other;

The second crushing layer 30 is disposed in the second grinding chamber 12, and includes two crushing rollers 31 and two grinding blocks 32, where the two grinding blocks 32 are disposed opposite to each other, and the two grinding blocks 32 are laminated on two ends of the inner side surface of the second grinding chamber 12; the two crushing rollers 31 are arranged between the two grinding blocks 32 and are used for further crushing materials;

The third crushing layer 40 is disposed in the third grinding chamber 13, and includes a guide hopper 41 and four press rollers 42, where the guide hopper 41 is disposed at a junction between the second grinding chamber 12 and the third grinding chamber 13, and the four press rollers 42 are attached to the bottom of the third grinding chamber 13.

Specifically, the housing 10 is the external structure of the metal mill and serves to house and isolate the metal milling process. The first, second and third grinding chambers 13 are critical areas within the housing 10 which are connected in sequence allowing successive grinding and refining of the metal particles to step through the different grinding layers. The first comminution layer 20 is located in the first grinding chamber 11 and consists of two parallel arranged main shafts 21 and a plurality of crushing teeth 22. The teeth are intermeshed for primary comminution and comminution of the metal particles. The method has the advantages that the massive metal materials are primarily crushed, a foundation is provided for the subsequent crushing process, and the production efficiency is improved.

Further, the second grinding chamber 12 is internally composed of two crushing rollers 31 and two grinding blocks 32, the two grinding blocks are oppositely arranged, and the grinding blocks 32 are laminated at two ends of the inner side surface of the second grinding chamber 12. Two crushing rollers 31 are used for further crushing the metal material. The metal particles are further refined, and the quality and consistency of the powder are improved. The third pulverizing layer 40 is located in the third grinding chamber 13 and includes a guide hopper 41 and four press rollers 42. The guide hopper 41 directs the particles through the appropriate location and four rollers 42 apply pressure to further refine the particles. The third pulverizing layer 40 continuously refines the metal particles by the synergistic effect of the press roller 42 and the guide hopper 41, and ensures the consistency and fineness of the particles.

In summary, the metal mill is characterized in that metal particles are gradually refined, and the quality and consistency of metal powder are improved. The method is suitable for application scenes of production and processing of various metal powders, and can be applied to the fields from manufacturing industry to material science. Meanwhile, a hydraulic rod and a temperature control system are further arranged in the machine, so that the pressure and the temperature are accurately controlled, and the optimal crushing effect is ensured.

In one embodiment, the motor 50 is disposed on the housing 10 and extends into the central axis of the spindle 21 for providing power.

Specifically, the motor 50 is mounted on the housing 10 of the metal mill, which makes the motor 50 a power source for the entire apparatus. It is typically mounted on the exterior of the housing 10 for repair and maintenance. Mounting the motor 50 on the housing 10 protects the motor 50 from the external environment and also facilitates maintenance and repair work. This helps to extend the life of the motor 50 and improves the reliability of the device. Further, the axis of the motor 50 is aligned with the central axis of the main shaft 21, which means that the output shaft of the motor 50 is on the same line as the main shaft 21. The motor 50 is directly connected to the main shaft 21 in this way, transmits power to the main shaft 21, and drives the pulverizing process of the metal pulverizer. This direct axis alignment ensures efficient power transfer and reduces energy losses. In addition, this connection provides a higher control accuracy for better management of the comminution process.

Still further, the motor 50 is powered by rotating its output shaft. When the motor 50 is started, the output shaft starts to rotate, transmitting power to the main shaft 21 aligned with its axis. The main shaft 21 is driven to drive the crushing teeth 22, the crushing roller 31, the pressing roller 42 and the like in each crushing layer to perform the tasks of crushing and refining the metal particles.

In a specific embodiment, the first grinding chamber 11, the second grinding chamber 12 and the third grinding chamber 13 are all fixed by threads.

In particular, the connection between the first, second and third grinding chambers 13 is made by screwing, i.e. they are screwed on their engagement surfaces, which are tightly connected together by rotation. The use of threaded fasteners can provide a strong mechanical connection, ensuring a tight fit between the grinding chambers. This helps to prevent loosening or displacement during operation of the metal mill, thereby maintaining stability and consistency of the apparatus.

Further, the design of the fixed connection through the threads is suitable for various application scenes of the metal mill, and particularly the field requiring high precision and high efficiency. For example, powder metallurgy, materials processing, advanced alloy preparation, and high performance materials manufacturing all require stable comminution processes. The stability and consistency of the comminution process are important because they directly affect the quality and properties of the final metal powder. By means of the threaded fixation, it is ensured that the connection between the grinding chambers is always kept in a controllable and predictable state, thereby improving the efficiency and quality of metal comminution. In addition, this connection also facilitates maintenance and replacement of the grinding chamber components to meet different operational requirements.

In a specific embodiment, a plurality of the crushing teeth 22 are detachably connected to the main shaft 21.

In particular, the breaker tooth 22 can be easily detached and attached to the main shaft 21. Typically, such attachment may be by threads, detents, pins, or other suitable mechanical attachment. The design allowing the crushing teeth 22 to be detachably connected with the main shaft 21 has several advantages. First of all, it makes it very convenient to replace or maintain the crushing teeth 22 without having to disassemble the whole main shaft 21 or the crushing chamber. Second, this allows for the selection of different types or sizes of crushing teeth 22 depending on different processing requirements or material types, thereby increasing the flexibility of the apparatus.

Further, when the crushing teeth 22 need to be replaced or installed, an operator can use an appropriate tool to attach or detach the crushing teeth 22 to or from the main shaft 21. This typically involves inserting the breaker tooth 22 into a corresponding connection point on the main shaft 21 and securing it firmly using threads, pins or other means of connection. This process is simple and intuitive, without the need for specialized skills or complex tools. Thus, it increases the ease of use of the apparatus and reduces the downtime for replacement of the crushing teeth 22. Furthermore, because the breaker teeth 22 are removable, they are easily serviced and replaced on a regular basis to maintain the performance of the apparatus.

In a specific embodiment, the plurality of crushing teeth 22 are high carbon steel.

In particular, the plurality of crushing teeth 22 used in the metal mill are all made of high carbon steel. High carbon steel is a steel material with a relatively high carbon content, typically between 0.6% and 1.7%. The use of high carbon steel to manufacture the breaker teeth 22 may provide several advantages. High carbon steel generally has excellent hardness and wear resistance, which enables the crushing teeth 22 to remain sharp and durable for a long period of time, maintaining stable performance even when handling hard metals. In addition, the strength of the high-carbon steel can bear high pressure and impact, and the crushing efficiency is improved.

Further, the crushing teeth 22 are members that contact and exert pressure against the metal particles when the metal mill is in operation. Since they are made of high carbon steel, they are able to maintain hardness and sharpness when in contact with metal particles. Due to the hardness of high carbon steel, the crushing teeth 22 are able to effectively cut and crush the metal particles, ensuring uniform and thorough crushing of the metal powder. Furthermore, their wear resistance enables the breaker teeth 22 to be used for a long period of time without frequent replacement, reducing maintenance costs.

In one embodiment, the angle of the hopper 41 is designed to maximize the flow of particles for smooth separation of the material passing through the second pulverizing layer 30 to both sides of the third pulverizing layer 40.

In particular, the primary function of this feature is to optimize the flow of metal particles within the metal mill, ensuring that the particles are smoothly transported from the second pulverizing layer 30 to the third pulverizing layer 40 and distributed on both sides. As the metal particles pass through the second comminution layer 30 they enter the guide hopper 41. Due to the special design of the guide hopper 41, the angle therein is carefully considered to promote the flow of the particles. The particles are guided in a hopper shape to ensure that they are evenly distributed to both sides of the third comminution layer 40. This smooth particle distribution helps achieve a uniform pulverizing effect in the third pulverizing layer 40.

Further, during the metal powder preparation process, the metal particles must be uniformly distributed to the milling area to ensure consistent metal powder production. The special design of the hopper 41 ensures uniformity of the powder. In metal recovery and scrap treatment, metal nuggets or scrap need to be crushed in a metal mill. This feature ensures an even distribution of metal particles in the mill, improving the milling efficiency. In powder metallurgy, metal powders need to be mixed and compacted into a desired shape. A uniform metal powder distribution is critical to achieving a consistent metallurgical product, a feature that can help achieve this goal.

In a specific embodiment, a hydraulic rod is further disposed in the third crushing layer 40, and the hydraulic rod is disposed on a side surface of the pressing roller 42, so as to accurately adjust the pressure of different materials.

Specifically, the hydraulic rod is disposed in the third crushing layer 40 and is located at the side of the pressing roller 42, and functions to precisely adjust the pressure on different materials. The main function of the mill is to allow an operator to adjust the working parameters of the mill according to the nature and requirements of the metal material being processed, so as to ensure the optimal milling effect. When the metal material is transferred to the third crushing layer 40, the hydraulic rod is located at the side of the press roll 42. The operator can vary the pressure exerted by the pressure roller 42 on the material by adjusting the position of the hydraulic lever or applying a different hydraulic force. The crushing efficiency and fineness in the grinding process can be adjusted by changing the pressure so as to meet the requirements of different materials. This allows the metal mill to accommodate a wide variety of metal materials, from soft to hard metals, and different particle sizes and hardness.

Further, in the production of metal powders, different metal and powder specifications may require different milling conditions. Adjustment of the hydraulic stem ensures that a metal powder meeting the specifications is produced. Different process parameters may be required in the treatment of different types of scrap metal. The presence of the hydraulic shaft may help to adjust the metal mill to handle various waste materials. Powder metallurgy requires mixing and compacting metal powders into a desired shape. By adjusting the pressure of the pulverizer, the production of different powder metallurgy products can be realized.

In a specific embodiment, four pressing rollers 42 are uniformly wound around the bottom inclined surface of the third crushing layer 40, and the pressing rollers 42 are used for applying pressure to push the particles to the upper part of the grinding chamber, so that the particles continue to be ground under the combined action of the pressure and friction.

Specifically, four pressing rollers 42 are uniformly distributed on the bottom inclined surface of the third pulverizing layer 40, and they function to apply pressure to push the metal particles toward the upper portion of the grinding chamber. The main function of this is to continue the application of pressure in the third pulverizing layer 40 of the mill to promote the refinement and uniform distribution of the metal particles. The hydraulic system or mechanical device applies pressure to the rollers 42 and these rollers 42 will be subjected to the same force and will uniformly push the metal particles towards the upper part of the grinding chamber. The metal particles continue to be subjected to pressure and friction within the grinding chamber, resulting in their further refinement and uniform distribution.

Further, in producing metal powder, it is necessary to refine coarser metal particles into a desired powder specification. This feature ensures uniformity and fineness of the powder. In the treatment of scrap metal or metal recovery, the metal pieces may need to be further crushed into particles suitable for reuse. Uniform pressure helps achieve this goal. In powder metallurgy, the metal powder needs to be uniformly distributed and maintain a consistent density during the forming process. This feature helps to achieve consistency in the powder metallurgical product.

In a specific embodiment, the distance between the pressing roller 42 and the bottom of the third crushing layer 40 is adjustable, so as to obtain fineness of different degrees according to different requirements.

Specifically, the distance between the pressing roller 42 and the bottom of the third pulverizing layer 40 is adjusted as needed to achieve different fineness of the metal particles. The main benefit is that the adjustability of the grinding process is provided, so that operators can control the fineness of the metal powder according to specific requirements so as to adapt to different application requirements. Further, the user may use a mechanical device or hydraulic system to adjust the distance between the pressure roller 42 and the bottom of the third comminution layer 40. By increasing or decreasing this distance, the user can change the pressure exerted on the metal particles during the milling process. A smaller distance will apply more pressure resulting in finer particles, while a larger distance will apply less pressure resulting in coarser particles.

In a specific embodiment, a temperature control system is further provided in the housing 10, and controls the temperature to prevent overheating when the grinding chamber temperature is too high.

Specifically, a temperature sensor is installed in the pulverizer to monitor the temperature of the grinding chamber. When the temperature rises to a predetermined safety threshold, the temperature control system is started, and control measures are taken to reduce the temperature. This may be accomplished in a variety of ways, such as turning off the motor 50 to reduce friction, activating a cooling fan or liquid cooling system, etc. Once the temperature drops to a safe level, the system will continue to monitor and maintain a steady temperature.

Further, it is very useful in long-time operation and mass production of metal mill to ensure operational safety and product quality. In the production of metal powder, the temperature of the grinding chamber may rise due to friction and pressure. The temperature control system can ensure that the metal powder cannot be overheated in the production process, so that the product quality is maintained. In the processing of metallic materials, particularly for difficult-to-process materials, high strength grinding and cutting are required. The temperature control system can prevent the tool and the workpiece from overheating, prolong the service life of the tool and improve the processing quality.

While the application has been described with respect to the above embodiments, it should be noted that modifications can be made by those skilled in the art without departing from the inventive concept, and these are all within the scope of the application.
