Jet Mill WP System--Apply to Agrochemical Field

The Fluidized-bed Jet mill is actually such a device that using the high speed air flow to perform the dry-type superfine pulverizing. Driven by compressed air, raw material is accelerated to the crossing of four nozzles to be impacted and grinded by upward flowing air to the grinding zone

Products Details

 WP 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.

Product Description

Jet Mill System--Apply to Agrochemical flow scheme

First,Raw material feed from the feeder --the material transfer to the first 3 m3mixer for premixing, and dust collector will collect dust during the feeding process, then the second 3m3 mixer store mixed material,then enter into jet mill for milling, the output particle size can be adjusted by adjusting different rotating speed of the classifier wheel,. After milling, material will transfer to the cyclone through centripetal force of draft fan and dust collector on the top of the first 4m3 mixer, then transfer to the second 4m3 mixer for mixing before package or transfer to WDG system. PLC Control system The system adopts intelligent touch screen control, easy operation and accurate control.

Operational process and steps

1.The milling process is applying the fluidized-bed jet mill working principle with high efficiency, and the particle size distribution is uniform. 2.The feeding process is with the minus pressure air transportation, the exhauster is added to prevent the dust emanation. 3.Both the first and last mixing process are applying the double screw mixers or horizontal spiral ribbon blender which insure the mixing is sufficient and symmetrical. 4.The product outlet can directly connect to the auto packing machine. 5.The whole system is controlled with the remote PLC control. Convenient operation and maintenance, automatic equipment operation. 6.Low energy consumption: it can save 30%~40% energy compared with other air pneumatic pulverizers. 7. It is applicable to crushing high mixing ratio materials difficult for crush and viscous materials.

Performance characteristics

Our Service

Advantages: 1 .Pipeline connection between dust collector and finished products outlet prevent dust leaking out, realize no dust packaging and no contamination. 2.Twin screw mixer has long stirrer and screw design,which keep completely mixing material from settling down under the action of the revolution and rotation.A. Continuous modelApplied to mass production  (QDF-400 Recommended product for agrochemical industry)B. Continuous model, Applied to mass production(QDF-400 Horizontal spiral ribbon mixer design)Advantages: 1 .Raw material hopper has mixing rod design, and the screw is enough long till the bottom to keep material flow smoothly. 2.Horizontal spiral ribbon mixer advantage: It is more convenient to make certain products which needs to add adjuvant or other chemicals at the finished product. And the mixing is much better and more accurate than the twin screw mixer. lower body height than Twin screw mixer, easy to install.C.Continuous model,Applied to mass production(QDF-600 Twin screw mixer design)Advantages: Both the first and last mixing process are applying the double screw agitators which ensure the mixing is sufficient and symmetrical. The conical design keep the material flowing down smoothly.D. Simplified model, Applied to batch production(QDF-400 Upper feeding mode)Advantage: Cyclone separator and Dust collector: Add vibration meter to the cone part to avoid accumulation of material.E.Simplified model, Applied to batch production (QDF-400 Bottom feeding mode)Advantage: Cyclone separator: Add one more cyclone separator after the feeder to disperse raw material flow direction and avoid accumulation of material.The Fluidized-bed Jet mill is actually such a device that Material fed into the main machine by a dosing feeder, the powdered material enters into the classifying area,they are impacting each other in the grinding chamber by the action of centrifugal force from high speed rotating classifier wheel and  of centripetal of draft fan, the qualified powder is collected by the cyclone and bag filter,the oversized powder is continued to grinding.
