The material enters the crushing room through the material feeder. The compression air into the crushing nozzles. The material gains acceleration in the ultrasonic jetting flow and repeatedly impact and collide at the central converging point of the crushing room until it is crushed.
The crushed material enters the grading room with the upflow.
Because the grading wheels spin at high speed, when the material ascends, the particles are under the centrifugal force created from the grading rotors as wells as the centripetal force created from the viscosity of the airflow.
When the particles is under the centrifugal force larger than the centripetal force, the coarse particles with larger diameter than the centripetal force, the coarse particles with larger diameter than the required grading particle will not entre the inner chamber of the grading wheel and will return to the crushing room to be crushed.
The fine particles that comply with the diameter of the required grading particles will enter the grading wheel and flow into the cyclone separator of the inner chamber of the grading wheel with the airflow and get collected by the collector.
The filtered air is released from the draft fan after the filter bag treatment.
Jet Mill System--Apply to Agrochemical flow scheme
This system is a perfect combination of jet mill technology, mixing
technology and intelligent control technology. which is a satisfying product
for pesticides to multi-mix and remix, Meanwhile, it meets environmental
request that no dust during the whole process.
We have more than 10 technical talents who have been engaged in the
system design for more than 20 years in the powder industry and have rich
experience in pulverizing,mixing,drying ,pelletizing,packaging,and powder
conveying.in Agrochemical-WP/WDG production lines, We can design the
flowchart according to clients’ requirements to meet customer's crushing
requirements for various materials.
a. No rise in temperature: the temperature will notincrease as the material are pulverized under the working condition of pneumaticexpansion and the temperature in the milling cavity is kept normal.,little abrasion and low noise.
b. No contamination: The whole process iscontamination-free as the materials are moved by airflow and crushed throughimpact and collision each other in air proof condition.
c. Feeding process is enclosed with negativepressure air transportation, no powder pollution. finished productsoutlet can connect directly with packing machine , no waste.
d. The milling process apply thefluidized-bed jet mill work principle ,highefficiency, uniform distribution particles, powerful production capacity.
e. Compactstructure, easy installation and dismantlement. easy to clean the equipment.
f. Superfineand uniform particle size and fineness can be 0.5-30um.The whole system iscontrolled by remote PLC .
The whole Jet Mill system is composed of the aircompressor, oil remover，air storagetank, air freeze dryer, air filter, fluidized bed jet mill, cyclone separator,dust collector, draft fan and mixers, water film scrubber and others.
