MQP series Spiral jet mill

Compressed gas is used to pass the feeder ejector to bring the ground raw materials into the grinding chamber, and driven by the high-speed airflow from multiple nozzles, it is sprayed on the grinding wall in a tangential manner to achieve the effect of friction grinding. By adjusting the longitudinal depth of the grinding chamber, adjusting the grinding pressure or feeding speed, the fineness of grinding can be controlled. Compared with the fluidized bed jet mill, the controllability of the pulverization fineness is less.
 

• Available particle size D50:1.5-45μm
• Many nozzles are installed for high grinding efficiency
• Free of transmission parts, automatic classifying structure.
• Good particle shape, narrow particle size distribution.
• 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. Also suitable for depolymerization.
• Constant temperature or low temperature, medium-free grinding, especially suitable for materials of heat sensitive, low melting point, sugary, volatile nature.
• The grinding process is completed by the collision of the materials themselves., Fully self-grinding, So this device is durable and products purity is high in contrast.
• Could lining with ceramic internal of Mill, ensuring non-contact with metal throughout the grinding for high purity of the final product.
• Achieve explosion-proof design, no safety hazards, cleaning is very simple, easy to disassemble and replace parts.
• Grinding is in closed system, low dust and noise, clean and environmentally friendly.
• PLC control system, easy operation.
• 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.

MQP Spiral Jet Mill(Disc Jet Mill) works with cyclone, bag filter and suction fan to form a complete grinding line. Compressed air flow after filtration and drying would go into milling chamber from nozzles and meet in the center area, where material would be impacted and ground and sheared. Qualified fine powder would be output and go into cyclone or bag filter, while oversize powder would back to milling area to be milled again.
