Product Detail

In the past, multiple-step processing such as the conventional grinding-classifying-process with fine impact mills and subsequent coarse grain separation in an air classifier, was the process of choice.


PQW Fluidised Bed Opposed Jet Mill - Suitable for fine grinding of all dry powders without contamination.Basically, the grinding energy generated by the material alone through air flow is self-grinding, and the machine itself has no wear.Air mill with adjustable speed classifier, to adapt to the required material fineness.It can adjust various grinding parameters and consistency of product quality are guaranteed.Even the hardest materials can be crushed in air mill.Suitable for materials with high purity and low temperature requirements, such as pharmaceuticals; Equipped with inert gas protection system, it is also applicable to inflammable and explosive, materials that can't be oxidized or contaminated,such as metal powder, lithium iron phosphate and other new industries.

Grinding and Classifier technological process:

PQW fluidised bed opposed jet mills is the latest generation of ultra-fine pulverizer. Set the world's most advanced multi - nozzle technology, fluidised bed technology and vertical classification technology are integrated to realize the diversification of flow field, fluidization of material layer, classification of vertical and mechatronics integrated technology system is the development direction of this fluidized bed jet mills.
