Fluidized bed airflow pulverizer

Fluidized bed airflow pulverizer

Working Principle:

It is achieved by compressing air through freeze-drying and filtering, allowing clean air to enter the crushing chamber at supersonic speed through the crushing nozzle, making the material in a fluidized state. The accelerated material converges at the intersection of several nozzle jet streams, producing intense collisions, friction, and shear to achieve ultrafine particle crushing. The material enters the grading zone with the rising airflow, and due to the high-speed rotation of the grading wheel, the crushed particles are simultaneously subjected to the centrifugal force of the grading wheel and the centripetal force of the fan, achieving the screening effect. Particles that meet the fineness requirements enter the next collection step through the gap of the grading wheel, while particles that do not meet the requirements return to the crushing chamber for further crushing.

Characteristics of Airflow Crusher:

1. Not heating up, as the material is crushed under gas expansion, the temperature of the crushing chamber is controlled at room temperature, and the temperature will not increase.

2. No pollution, because the material collides and crushes itself under the influence of airflow, without being carried into the medium, so there will be no pollution during the material crushing process.

3. Low wear and tear, as the main crushing effect is particle impact and collision, high-speed particles rarely collide with walls, making it suitable for crushing materials with a Mohs hardness of nine or above.

4. Low energy consumption, saving 30% to 40% energy compared to other types of airflow crushing.

5. Inert gas can be used as a medium for crushing flammable and explosive materials.

6. The use of Xian's touch screen and programmable logic controller (PLC) enables automated control.
