Unique Advantages

Wide range of application

It is suitable for dry grinding, constant temperature or low temperature non medium grinding of all kinds of materials with Mohs hardness below 9. It can be used in series with multi-stage classifier to produce products with multiple particle sizes at one time.

High precision grading rotor

The world's leading high-precision grading rotor, linear speed up to 80m / s, to ensure that the vertex cutting accuracy, can meet the demanding product requirements.

Automation control system

The control system adopts program control, which is easy to operate; the motor can be connected by belt, which can improve the speed and break through the problem of no high-speed motor.

Large scale and large capacity

The grading wheel can automatically separate materials through air flow, without coarse particles; the precise weighing control system can be selected, with high product stability and good consistency.

Working Principle & Equipment Characteristics

Jet Mill, cyclone, bag filter and fan constitute a complete milling system. After the compressed air is filtered and dried, it is sprayed into the milling cavity at high speed through Laval nozzles. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be milled. The milled materials rise with the suction of the fan. The air flow moves to the classification area, the coarse and fine powder are separated under strong centrifugal force generated by the high-speed rotating classification turbine. The fine particles that meet the particle size requirements are through classifier wheel and collected by cyclone and bag filter; the coarse powder drop to the milling area and continue to be milled.

Working principle of horizontal single rotor fluidized bed jet mill

Working principle of horizontal multi rotor fluidized bed jet mill

Horizontal & Single Classifying Wheel

Fluidized Bed Jet Mill

The particle size range of D50:1-25μm;
The particle shape is good and the particle size distribution is narrow;
The rotor speed can be adjusted by frequency conversion, and the particle size distribution can be adjusted flexibly;
The design of air screen type secondary air has high energy utilization rate, helps material flow and improves powder separation efficiency;
The whole system is closed comminution, less dust, low noise, clean and environment-friendly production process;
The control system adopts program control, which is easy to operate.

Multiple Classifying Wheel

Horizontal Fluidized Bed Jet Mill

The particle size range of D50:1-25μm;
Multi stage rotors installed horizontally can achieve higher output than single rotor;
Each grading rotor is equipped with a speed sensor, and the rotor speed can be adjusted by frequency conversion to flexibly adjust the particle size distribution;
It is easy to realize large-scale and large capacity. Take talc as an example, D50:≤3μm, and the capacity can reach 57t/h;
The whole system is closed comminution, less dust, low noise, clean and environment-friendly production process;
The control system adopts program control, which is easy to operate.
