Five: Process Description:
- the machine combined crush, grade together, crushing ,grading one-time completion. Equipment structure is simple, small footprint.
- Jet mill crushing principle is the compressed air after cooling, filtration, drying, the formation of supersonic air through the Laval nozzle into the crushing chamber, the material fluidized, accelerated material convergence at several nozzle intersection, resulting in a violent collision, Friction, shear and the formation of ultrafine particles of particles. So this crushing form is no media crushing, crushing the highest purity of the material, also a low-temperature crushing process.
- With the high level of automation , the final materials granularity can be adjust.
the crushed material rises to the turbine grading area under the action of airflow. Under the rotation of the grading turbine, the particles are subjected to centrifugal force and centripetal force due to the viscosity of the air flow. When the particle is centrifugal force greater than the centripetal force, That is, above the grading diameter coarse particles along the barrel wall spin down to the crushing area to continue to crush, and qualified particle size particles with the air through the turbine into the cyclone collector. As the turbine speed control by the inverter, can achieve stepless speed regulation, to ensure the reliability of the classification performance and operational flexibility, and at the same time according to the requirements of different particle size requirements of the product, the particle size is very concentrated, especially use for medicine, food, chemicals industry.
- More than 95% qualified material into the cyclone collector and be discharged .
- After the powder enters the electric pulse dust collector, the dust is attached to the filter bag, and the dust attached to the bag is collected under the injection of the pressure airflow, and the filtered clean air is discharged through the draft airfan after filtering.
- Feeding system by screw feeding ,By the frequency control motor speed, in order to achieve quantitative feed.
- Whole set machine control by the electric control cabinet .
