Description

Technical Field

[0001] The utility model relates to the technical field of pulverizing equipment, in particular to an ultra-fine pulverizer which is convenient for discharging materials. Background Art

[0002] Ultrafine pulverizer is a mechanical device used to crush materials to micron or nanometer level. It uses powerful mechanical force to crush materials into extremely fine powder. It is widely used in food, medicine, chemical industry, ceramics and other fields.

[0003] The discharge of the ultrafine pulverizer usually needs to pass through the sieve holes. The main function of the sieve holes is to control the particle size of the powder and ensure that the particle size of the final product meets the requirements. In the ultrafine pulverization process, the material is crushed into tiny particles, but the sizes of these particles are not consistent, and they need to be screened through the sieve holes to separate the powder with qualified particle size from the unqualified powder. After the ultrafine pulverizer completes the pulverization of the material, because the sieve holes are the key components for controlling the particle size of the powder, during the pulverization process, the material is impacted and rubbed into tiny particles at high speed, and these particles will be discharged through the sieve holes. Moreover, since the aperture of the sieve holes is usually very small, some smaller powder particles may be stuck in the sieve holes, resulting in their inability to be discharged smoothly. In addition, factors such as the humidity, viscosity, and fiber content of the material may also affect the fluidity of the powder, making it easy to accumulate at the sieve hole position.
