S-MQL Vertical Steam Jet Mill

Upgraded from a conventional jet mill, adopts unique high-temperature mechanical sealing technology and cooling technology, and uses high-temperature steam as the kinetic energy medium for crushing. Through the specially designed Laval nozzle, the animal material is collided and crushed at high speed. The crushed materials enter the forced eddy current classification, the qualified materials enter the heat preservation collection system for collection, and the coarse materials fall into the crushing zone to continue crushing. The whole process is completed under the dry method.

Product Description

Performance characteristics

Available particle size D50:0.5-10μm.
Nano particle size is available.
Saturated steam of working pressure 8-40 bar and temperature 230℃-360℃, 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, produce finer powder.
Stronger grinding ability and energy, easy to achieve finer powder.
Compared with normal jet mill, higher energy efficiency, lower operating cost.
The grinding process is completed by the collision of materials themselves., Fully self-grinding, So this 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, 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 classifying wheel and nozzle could made by wear-resistance material, and also ensuring non-contact with metal throughout the grinding for high purity of the final product.
Single or multi-classifying wheel are installed Vertically.
Rotating speed of wheel is controlled by inverter, particle size can be adjusted freely.
Grinding is in closed system, low dust and noise, clean and environmentally friendly.
PLC control system, easy operation.
Can be used for ultra-fine processing of high viscosity products.
The motor can be connected with belt to increase rotating speed.
Can be used in series with multi-stage classifiers to produce products with multiple sizes.
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

Steam Jet Mill(Steam kinetic energy mill) Upgraded by conventional jet mill, adopts unique high-temperature mechanical sealing technology, cooling technology, high-temperature steam as grinding kinetic energy medium, specially designed Laval nozzle drive high-speed collision and grinding of materials. The grinded material enters the forced vortex classification, the qualified materials enter the heat preservation collection system, and the coarse materials fall into the grinding zone to continue the grinding, the whole process is completed under the dry process.
