Flat airflow pulverizer technical principle

The pulverization mechanism that is mainly applied to the jet mill determines its wide application range and high fineness of finished products. Typical materials are: super-hard diamond, silicon carbide, metal powder, etc. High-purity requirements: ceramic pigments, medicine, Electronics, battery materials, fine chemicals, etc., low temperature requirements: medicine, food, PVC, etc. By changing the ordinary air of the gas source part into an inert gas such as nitrogen or carbon dioxide gas, the machine can be used as an inert gas protection device, and is suitable for crushing and classifying processing of flammable, explosive, and easily oxidizable materials.

The working principle is as follows: the flat airflow pulverizer and the cyclone separator, the dust collector and the induced draft fan form a complete set of pulverizing system. After the compressed air is filtered and dried, it is sprayed into the crushing chamber at high speed through the Laval nozzle. At the intersection of the multiple high-pressure air streams, the material is repeatedly crushed, rubbed, sheared and crushed, and the crushed material rises under the action of the fan. The airflow moves to the classification zone, and the coarse and fine materials are separated under the strong centrifugal force generated by the high-speed rotating classification turbine. The fine particles meeting the particle size requirements are collected by the classification wheel into the cyclone separator and the dust collector, and the coarse particles are lowered to the crushing zone to continue to be crushed. .

Flat jet mill features:

1. Suitable for ultra-fine pulverization of dry and brittle materials, it is easy to obtain a few micron materials;

2. Due to the self-grinding and pulverizing between the powders, the products are not easy to be polluted and the purity is high;

3. The flat airflow pulverizer has no running parts, except for the normal wear of the lining, other parts are generally not damaged;

4. Closed without dust and flying, environmental protection;

5. Low noise, no vibration, easy to remove and wash;

6. It can realize large-volume continuous production with high degree of automation;

7. The flat jet mill can select the corresponding lining material (mainly around the crushing chamber and the inlet and outlet pipes) according to the materials of different properties, so as to solve the hard material (Mohs hardness is not more than 9) and the sticky wall The problem caused by the smashing of materials.
