[0053] In one embodiment of the pulverizing apparatus, the structure may include a series of toothed concentric metal discs specifically designed for efficient and effective material handling. These metal discs may be directly attached to a rotor, which includes bearings providing rigid rotational mounting to ensure precise and smooth operation during the pulverizing process.
[0054] In addition, the rotor can be equipped with magnets, enabling direct drive via the motor stator coils, utilizing a brushless DC motor direct drive design.
[0055] The detailed description of this embodiment may include the following aspects: The feature set may include, or preferably, consist of concentric metal grinding discs: these discs have teeth designed for shearing, cutting, crushing, or grinding materials, and can be arranged concentrically to provide a highly efficient grinding surface. This arrangement also contributes to a more uniform particle size distribution and improved output material quality.
[0056] Rigid rotary mounting: The rotor, directly attached to the metal grinding disc, can be mounted using bearings. These bearings provide stable and rigid rotational support, ensuring precise and consistent operation during the grinding process. This results in better material handling control and reduced wear on device components.
[0057] Direct drive of brushless DC motors: This device benefits from brushless DC motor design by incorporating magnets within the rotor and using the motor stator coils for direct drive. This design reduces complexity, maintenance requirements, and frictional losses, while improving the overall efficiency, reliability, and lifespan of the device.
[0058] In various embodiments of the pulverizing apparatus, adjustments to rotational speed, material feed rate, and other processing parameters can significantly impact the physical properties and underlying structure of the output material. By fine-tuning these parameters, users can customize the pulverizing process to achieve specific material characteristics and properties required for a particular application or industry. For example, adjustments to the pulverizing process may affect: Structure preservation: In some cases, gentle and precise pulverization may be necessary to preserve the underlying cellular structure, particle size, or texture of a material. This is especially important for organic materials with complex structures, where maintaining the integrity of these structures can affect the material's function or performance in a particular application.
[0059] Grinding: In some applications, a more vigorous grinding process may be required to increase permeability and improve the solubility of the output material during dissolution. This is particularly important in the pharmaceutical, food processing, and chemical industries, where dissolution rate and material interactions directly affect product performance.
[0060] To adapt to these different processing requirements and material properties, the crushing device can be enhanced through several design improvements: Speed control: The device can be equipped with a speed control mechanism to allow users to adjust the rotational speed of the feature group, thereby enabling precise control of the crushing process and its impact on the structure and properties of the output material.
[0061] Material-specific feature sets: The ability to design and manufacture customizable feature sets to suit specific materials or applications, providing greater flexibility and adaptability for different industries and use cases.

[0063] Pre-treatment or post-treatment: This device can be combined with additional equipment or processes, such as pre-treatment for material conditioning or post-treatment for material separation or sorting, to further enhance the performance and properties of the output materials.
[0064] In various embodiments of the pulverizing apparatus, static electricity can be a significant issue during the pulverizing process, posing challenges in handling, processing, and ensuring consistent output material properties. To mitigate these issues, the apparatus can be equipped with systems designed to manage and reduce static electricity generated during pulverization. These systems can be passive or active in nature, depending on the specific requirements and desired outcomes.
[0065] Passive static electricity mitigation systems: These systems utilize physical components, such as baffles or metal wires, to agglomerate particles into slightly larger clumps. By increasing particle mass, the forces generated by triboelectric attraction can be overcome, helping to reduce the impact of static electricity on the output material. Passive systems offer a simple and cost-effective solution for managing static electricity during the pulverizing process.
[0066] Active static electricity mitigation systems: In more advanced embodiments, the device can be equipped with an active, electrically driven system, such as an ionizer. An ionizer can utilize a series of conductive needles, typically made of tungsten carbide, to apply a high voltage to ionize the surrounding air and neutralize any charge on the output material. Active systems offer a more robust and effective solution for managing static electricity, especially in situations where static problems are more severe or persistent.
[0067] It is worth noting that although friction during the crushing process generates triboelectric effect, there may also be cases where the net charge remains zero, and the static electricity problem is caused by the migration or separation of positive and negative charges between different particles.
[0068] Other improvements to the pulverizing device may include: Antistatic materials: Using materials with low static electricity generation properties to construct feature groups or other components in contact with the material can help reduce the total static electricity generated during the crushing process.
[0069] Environmental control: Implementing humidity and temperature control systems in the processing environment can help manage conditions that lead to static electricity, thereby improving overall process stability and consistency of output materials.
[0070] Grounding: Ensuring proper grounding of the equipment and its components helps dissipate any accumulated static charge, reduces the impact on output materials, and improves overall process safety.
[0071] By incorporating these improvements and systems into the design of crushing equipment, static electricity-related problems can be effectively managed and mitigated, thereby improving the quality of material handling, processing, and output in a wide range of applications and industries.
[0072] These improvements and changes in the design of the pulverizing unit can help improve the overall performance, efficiency, and adaptability of the unit, making it suitable for a wide range of materials and applications across various industries.

[0126] Figure 5 Another cross-sectional view is depicted according to an embodiment of the invention, adapted to produce a relatively coarse grind. The annular grinding disc 20 has a varying geometry on its inner surface forming a set of features. This varying geometry on the inner surface of the annular grinding disc 20 can be given by varying distances between the discs, such that the distance between a first pair of discs on the inner surface of the annular grinding disc 20 can differ from the distance between a second pair of discs. Therefore, a region of a specific geometry can be selected by translating the position of the annular grinding disc 20 relative to the cup-shaped member 10. In the described configuration, the selected specific geometry or region has a wider distance between the two discs on the inner surface of the annular grinding disc 20, resulting in a relatively coarse grind. Adjustment of the selected region can be performed by rotating an adjusting ring 510. The adjusting ring 510 may include threads through which the distance between the upper portion 520 and the lower portion 530 of the device can be changed.
