SCWN-Q Series Jet Mill Operating Principle
System Composition:
The jet mill system consists of an air compressor, air storage tank, air dryer (including filter), jet mill main unit, high-precision classifier, cyclone collector, pulse bag dust collector, high-pressure induced fan, control cabinet, loading and unloading systems, etc.
Operating Principle:
Compressed air is chilled, filtered, and dried before being injected through nozzles into the milling chamber as supersonic jets, fluidizing the materials. The accelerated materials converge at the intersection of several nozzle jets, generating intense collisions, frictions, and shears to achieve ultrafine grinding of particles. The grinded materials are then transported by the ascending airflow to the impeller classification zone. Under the action of the classifier's centrifugal force and the fan's suction force, coarse and fine powders are separated. The coarse powders return to the milling chamber for further grinding due to their own gravity, while the qualified fine powders enter the cyclone collector along with the airflow. The ultrafine dust is collected by the bag dust collector, and the purified gas is discharged by the induced fan.
Performance Advantages and Features:
Based on the traditional fluidized bed mill design, combined with our unique self-dividing classification technology, our jet mill outperforms domestic and international counterparts.
Low energy consumption, achieving 30% energy savings compared to traditional fluidized bed jet mills.
Built-in self-dividing micropowder classifier, ensuring concentrated particle size distribution and no oversized particles in the finished product.
Compact structure with a small footprint.
No material retention and dead corners in the milling chamber, making disassembly, cleaning, and sterilization easy. Convenient for changing product types, meeting GMP requirements.
Low-temperature media-free grinding, especially suitable for materials with low melting points, thermal sensitivity, sugar content, and volatility.
For flammable and explosive materials, inert gas can be used as a medium for fully enclosed grinding, with low loss due to its recycling.
Wide range of grinding particle sizes, adjustable from 3 to 180um; various models available with production capacity ranging from 1 to 3000kg/h.
Negative pressure production, no dust pollution, and excellent working environment.
High automation, strong stability, and easy operation.
Installation, Commissioning, and Warranty:
The supplier is responsible for guiding the installation, commissioning, and training of 1-2 commissioning personnel free of charge. The equipment warranty period is 12 months after acceptance by the demander, and the supplier will provide vulnerable parts of the equipment on a long-term basis at cost.
