MQP series Spiral jet mill for medicine

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.
• Seamless and smooth design, easy disassembling and cleaning.
• Free of transmission parts, self-classifying structure.
• Good particle shape, narrow particle size distribution.
• CIP/SIP design is optional.
• Meet GMP/FDA requirements.
• 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.

Jet Mill works with cyclone separator, dust collector and suction fan to form a complete grinding system. 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. Milled powder would go up to the classifying chamber by the air flow from suction fan. The high-speed rotation of classifier wheel would create a strong centrifugal force to separate coarse powder and fine powder. Qualified fine powder would go through the wheel vane then into the cyclone separator or dust collector, while mixture of coarse powder and fine powder would fall down to the milling chamber to be milled again.

Technical Parameters

Note: The production capacity is closely related to the particle size, specific gravity, hardness, moisture and other indicators of the raw materials. The above is only for selection reference.
