Non-metallic Mineral Fluidized Bed Jet Mill

Non-metallic mineral fluidized bed jet mill is a type of equipment used for grinding and processing non-metallic minerals. It is a highly efficient and energy-saving machine that uses compressed air to create a high-speed jet stream that impacts and grinds the materials.

The non-metallic mineral fluidized bed jet mill is particularly useful for grinding and processing materials such as limestone, talc, kaolin, quartz, and other non-metallic minerals. These materials can be difficult to grind using traditional grinding methods, but the fluidized bed jet mill is able to achieve a high degree of precision and efficiency.

Working Principle of Horizontal Fluidized Bed Jet Mill

MQW jet mill is a Fluidised Bed Opposed Jet Mill, with built-in horizontal classifying wheels (single wheel or multiple wheels). After the compressed air is filtered and dried, it is sprayed into the grinding chamber through the Laval nozzle at high speed. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be crushed. The ground materials rise with the suction force of the fan. The airflow moves to the classifying area, under the strong centrifugal force generated by the high-speed rotating classifying 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 classifying wheel, and the coarse particles descend to the grinding area to continue grinding.

Technical Advantages of Horizontal Fluidized Bed Jet Mill

  • The grinding process is completed by the collision of the material itself, completely self-grinding, with minimal wear on the equipment, suitable forgrinding of various hardness materials.
  • The grinding form of fluidized bed collision can better maintain the shape of particles.
  • Low temperature and medium-free grinding, suitable for heat-sensitive, low-melting, sugar-containing, and volatile materials.
  • High-temperature and high-pressure grinding to achieve higher injection speed, lower dynamic viscosity, and highergrinding fineness and  efficiency.
  • Inner, classifying wheels, nozzles and other key components can be protected by wear-resistant materials such as alumina, zirconia, and silicon carbide, and organic materials to avoid contact with metal during the entire grinding process and obtain high-purity products.
  • The grading wheel is installed horizontally, which can better control the fineness of products with low density and produce finer products.
  • Inert gas closed-circuit cycle/explosion-proof design, which can meet the grinding of flammable, explosive, easy to oxidize, and easy to absorb moisture materials.
