Please contact our engineers to customize the equipment for you. Our experts will contact you within 6 hours to discuss your needs for machine and processes.

• Available particle size D50:1-25μm.
• Good particle shape, narrow particle size distribution.
• Speed of wheel is controlled by converter, particle size can be adjusted freely.
• Ultrafine powder product is stable and reliable.
• The jet mill is suitable for dry grinding of various materials with Moh's hardness below 9, especially for the materials with high hardness, high purity and high added value.
• Constant temperature or low temperature, medium-free grinding,especially suitable for materials of heat sensitive, low melting point, sugary, volatile nature.
• The world's leading high-precision classifier rotor with line speeds up to 80m/s, ensuring high precision for product requirements.
• High energy utilization rate, promote material flow, improve powder screening efficiency.
• The grinding process is completed by the collision of the materials themselves., Fully self-grinding, So The device is durable and the purity of products is high in contrast.
• Key parts like inner liner, classifying wheel and nozzle are made of ceramic such as aluminum oxide, zirconium oxide or silicon carbide, ensuring non-contact with metal throughout the grinding for high purity of the final
  The classifying wheel separates the material automatically with airflow, no coarse particles.
• Grinding is in closed system, low dust and noise, clean and environmentally friendly production process.
• PLC control system, easy operation.
• The motor can be connected with belt to increase the speed and break through the problem of high-speed motors without the well-known motor brand.
• Can be used in series with multi-stage classifiers to produce products with multiple sizes at one time.
• Weighing control system, high precision, optional, high product stability.
• Optional explosion-proof design, can also be upgraded to nitrogen circulation system to meet the ultra-fine grinding processing requirements of flammable and explosive oxide materials.

Working Principle

Fluidized Bed Opposed Air Jet Mill: After the compressed air is filtered and dried, it is sprayed into the grinding chamber at high speed through the Laval nozzle. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be crushed. The crushed materials rise with the suction of the fan. The airflow moves to the classification zone. Under the action of the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. The fine particles that meet the particle size requirements enter the cyclone separator and dust collector through the classification wheel for collection, and the coarse particles descend to the crushing zone and continue to be crushed.
