The SWFL130 vertical ultrafine pulverizer uses a vertical grinding and classification structure that combines impact, grinding, and airflow classification to achieve continuous ultrafine pulverization.
1. Feeding and Pre-Crushing
The material enters the machine through the top feeding inlet and first passes through a high-speed rotating impact hammer assembly. The larger particles are initially broken down by impact forces and are then thrown toward the internal liner under centrifugal force, completing the preliminary crushing stage.
2. Ultrafine Grinding
After pre-crushing, the smaller particles enter the lower grinding chamber. The chamber uses a combination of rotating and stationary grinding components.
The rotating disc drives the grinding media, such as ceramic balls or steel segments, at high speed, while the stationary disc remains fixed inside the chamber. The relative movement between these components generates impact, shear, and grinding forces, further reducing the material to the required micron-level particle size.
3. Airflow Classification and Discharge
After grinding, the material is carried upward by the positive airflow from the lower part of the machine and enters the high-speed classification rotor at the top.
The classifier uses centrifugal force to separate particles according to size. Coarse particles that do not meet the required fineness are thrown toward the chamber wall and fall back into the grinding chamber for further processing. Qualified fine particles pass through the classification rotor and are carried by the airflow to the discharge outlet for collection.
4. Continuous Circulation
The SWFL130 adopts a closed-loop grinding and classification process. Oversized particles automatically return to the grinding chamber without manual separation, allowing the machine to maintain continuous ultrafine pulverization and more consistent particle size control.
For customers requiring replacement or customized mechanical components for ultrafine pulverizing equipment, Hansheng Automation provides precision machining based on customer drawings and technical specifications, including non-standard parts manufactured to specific dimensional and material requirements.
