Lithium Manganate Jet Mill and Classifier

Working Principle:

After being cooled, filtered, and dried, the compressed air is propelled through nozzles to form supersonic airflows into the grinding chamber, fluidizing the material. The accelerated material converges at the intersection of several nozzle jets, undergoing intense collisions, frictions, and shears to achieve ultrafine grinding of particles. The ground material is then transported by the rising airflow to the impeller classification zone. Under the centrifugal force of the classifier wheel and the suction force of the fan, coarse and fine powders are separated. The coarse powder returns to the grinding chamber for further grinding due to its own gravity, while the qualified fine powder enters the cyclone collector with the airflow. The microfine dust is collected by the bag filter, and the purified air is exhausted by the induced fan.

Features:

1. Low energy consumption, achieving 30% energy savings compared to traditional fluidized bed jet mills.

2. Built-in self-dividing micro-powder classifier, resulting in concentrated particle size distribution and no oversized particles in the finished product.

3. Compact equipment structure with a small footprint.

4. No material residue or dead corners in the grinding chamber, easy to dismantle, clean, and sterilize, convenient for changing product varieties, and compliant with GMP requirements.

5. Low-temperature grinding without media, especially suitable for low-ignition point, heat-sensitive, sugar-containing, and volatile materials.

6. For flammable and explosive materials, inert gas can be used as a medium to achieve fully enclosed grinding. The inert gas is recycled with minimal loss.

7. Wide range of grinding particle sizes, adjustable finished particle diameters from 0.5 to 45um; complete range of models with production capacities ranging from 5 to 3000kg/h.

8. Negative pressure production, no dust pollution, and excellent environmental conditions.

9. High automation level, strong stability, and easy operation.
