The fourLaval-cavity nozles around the crushing chamber would accelerate the compressed air into supersonic flow.The material would be accelerated into up-and-down flow regime by the supersonic airflow in the crushing zone.
The accelerated materialparticles would smashinto each other at the intersection point of the nozles. The crushed materalithen sent to the grading area byupdraft.The high-speed rotation of the grading wheel would allow the qualified fine powder to enter the cyclone separator and collector along with the airflow.
Meanwhile, the coarse powder that fails to meet the requirements offineness retums to the crushing area forfurther crushing.
1、This machine is suitablefor the grinding ofbrttle dry powder materials whose Moh’ shardness is below grade9The grinding fineness canreach DS0<5um.
2、The grinding proces isfunctioned bythe mutualcollision betwen materialsand the materialrarely colid es with the inner wallof the cushing areaHlence,the abrasion is negligible.and the product will not be polluted.
3、Thefineness of the product can be adjusted byfrequency conversion of the grading whee, and the size distribution of the crushed productisnarrow.
4、The structure of the machine is simple and handle advantageous.
5、The lining of the mill cavity and the grading wheel are all made f alumina ceramics.
This machine is suitable for mineral, pesticide,chemical, ceramic materials, electronicmaterials and other ultrafine powder industry.
