Ultra fine pulverizer is a term that differs from traditional pulverizers. Its principle is designed based on the processing of ultrafine powders (ultrafine powders are generally larger than 325 mesh). Such as air flow mill, resonance mill (vibration mill), stirring mill, etc. The ultrafine grinding equipment is based on the dispersion system of ultrafine powder as the research object, and implements energy input. The increase in specific surface area of the powder is proportional to the square of the energy input. So ultrafine crushers are mostly medium grinding and grinding methods. There is a significant difference compared to traditional crushers. The difference in use is that there is less heat generation, slow temperature rise, uniform discharge particle size, no mixing of large particles and fine powder, and reasonable energy consumption. The resonant mill, also known as the high-frequency resonant mill, has the lowest energy consumption, while the airflow mill has a relatively higher energy consumption. The airflow mill needs to use a classifier to achieve crushing. The classifier is also an important component of the concept of ultrafine crushers. Its function is similar to the sieve in traditional crushers. In the process of choosing ultrafine grinding equipment, the first thing to do is to have a basic concept of the crusher and ultrafine grinding equipment to avoid falling into misunderstandings.
