Product Description

Single/multi-classfying wheel Ultrafine Fluided-Bed Air Jet Mill The jet mill grinding system consists jet mill, cyclone, bag filter and draft fan. Filtrated, desiccated and compressed air is ejected into the grinding chamber through Laval nozzle, the material is crushed, rubbed and cut repeatedly at the joint of several high-pressure jet air flow and finally pulverized. Then, the material will be classified into different sizes under the centrifugal force and centripetal force. Qualified fine particles is collected by the cyclone and bag filter, while oversize particles will be rejected to the grinding chamber for regrinding.

• 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.

Steam Jet Mill

The mill is upgraded from the conventional jet mill. Adopting unique sealing and cooling technology free from temperature rise for bearing, high-temperature steam is used as grinding medium. With a specially designed Laval nozzle, the material collides with each other at high speed, the ground material enters the forced turbine classifying area. Qualified fine powder is collected and the oversize falls into grinding zone for regrinding.

• Available particle size D50:0.5-10μm
• Nano particle size is available.
• Steam of working pressure 8-40 bar and temperature 230ºC-360ºC, both drying effect
• Higher speed of steam results in higher kinetic energy, strong grinding force, high-speed jet nozzle exit speed can reach 1020m / s, can produce finer powder
• Stronger grinding ability and energy, easy to achieve finer powder.
• Compared with conventional jet mill, higher energy efficiency, lower operating cost.
• 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.
• High speed and low viscosity, can achieve higher grinding efficiency and classification accuracy, reduce over-grinding, and obtain narrower particle size distribution.
• Good particle shape and high activity.
• The classifying wheel separates the material automatically with airflow, no coarse particles.
• 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 product.
• Single or multi-classifying wheel are installed horizontally.
• Speed of wheel is controlled by converter, particle size can be adjusted freely.
• Grinding is in closed system, low dust and noise, clean and environmentally friendly production process.
• PLC control system, easy operation.
• Can be used for ultra-fine processing of high viscosity products.
• The motor can be connected with a 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
