JZXPThe series of rotary jet mills is a new type of jet mill developed over years of research, integrating the features of traditional horizontal disc jet mills, target jet mills, opposed jet mills, and fluidized bed jet mills. It is characterized by low energy consumption and high output.

Working Principle of a Rotary Jet Mill：

The rotary jet air mill operates by passing compressed air through cooling, filtration, and drying processes before it is ejected through nozzles to form supersonic airflow into the crushing chamber. Under the influence of pressure differentials, the material becomes fluidized. The accelerated materials converge at the intersection points of multiple nozzles, undergoing intense impact, collision, friction, and shearing to achieve ultra-fine particle grinding. The finely ground powder is then transported by the upward airflow to the upper turbo classifier. Under the combined action of the centrifugal force from the classification wheel and the suction force of the fan, micro-powder meeting the required fineness is discharged and sent to the next stage for further classification or collection. The purified gas is expelled by the induced draft fan.

Equipment Features

JZXPThe series of rotary jet mills is a new type of jet mill developed over years of research through the organic integration of traditional horizontal disc jet mills, target jet mills, opposed jet mills, and fluidized bed jet mills. It features the following characteristics:

1Low energy consumption, high output: The unique crushing chamber design employs multi-force field collaborative crushing, which significantly improves crushing efficiency. Production has proven that this equipment features the lowest energy consumption and the highest output. Compared with traditional jet mills, it can save energy.30%, production increased2More than double.

2Low-temperature dry grinding: suitable for ultra-fine processing of Mohs hardness5Low melting point, heat-sensitive, fibrous, high polymer powder below grade;Flammable, explosive, and easily oxidized materials can be pulverized in a closed-loop system using inert gas as the medium, with the inert gas being recycled for reuse.

3The crushing particle size range is wide: the finished product particle size isd97=5～50umAdjustable within the range.

4Fully enclosed negative pressure operation, no dust pollution.
