Working Principle:

Pressurized gas generates a jet stream through the feeding nozzle, which draws the raw material into the mixing chamber and injects it into the crushing cavity at the lower end of the "O"-shaped loop via the Venturi tube. Under the action of high-speed jets from the surrounding crushing nozzles in the crushing cavity, the particles collide and rub against each other violently, achieving pulverization. The finely crushed powder is carried by the airflow through the riser into the primary classification chamber. Coarse particles, due to their greater centrifugal force, return to the crushing cavity via the downcomer for further grinding, while fine particles enter the secondary classification chamber with the airflow. Ultrafine particles with very low mass are separated by the classification vortex and exit through the central outlet into the collection system.

Features:
· The QON series loop jet mill is suitable for the ultrafine grinding of dry, brittle materials, easily producing micron and sub-micron sized particles.
· Relies on self-grinding between particles to obtain high-purity products.
· Utilizes a secondary internal classification structure to improve product fineness and particle size uniformity.
· Equipped with wear-resistant liners to extend the mill's service life and adapt to the grinding of harder materials.
· The adiabatic expansion of pressurized gas creates a cooling effect, allowing grinding to occur at low temperatures, making it particularly suitable for low-melting-point and heat-sensitive materials.
· The production process is conducted in a closed pipeline system, with no dust emission.
· Noise level is below 70 decibels, with no vibration.
· Enables continuous production and automated operation, also achieving mixing and dispersion during the grinding process. By modifying process conditions and partial structures, it can perform drying, grinding, and coating activation treatments.
