Thifenosulfuron dry suspension agent granulator

Spray granulation is a method in which the suspension is sprayed in a hot gas stream in a drying chamber with a atomizer to rapidly evaporate the water to produce fine dry granules. In a few seconds to complete the material liquid concentration, drying, granulation process. After the wet pulverized slurry is first atomized into mist microdroplets, the water is evaporated by the hot air away, the solid phase within the droplets gathered into dry particles. Spray granulation made of particles for the hollow porous, so in water wetting, disintegrating performance, and a very high suspension rate.

     Dry suspending agent and water dispersible granules are essentially one thing, the difference is that the dry suspending agent is made after the use of water suspension spray granulation method, so the appearance of the general spherical, and water dispersible granules mainstream Dry process, the more common for the extrusion granulation and sulfide bed granulation
1, dry suspension agent definition:
Dry suspending agent is one of the pesticide formulations, it is dehydrated by water suspension, as the name suggests - dry suspension agent (English code DF). In recent years, the Ministry of Agriculture Pesticide Test will dry blends with water dispersible granules together, collectively referred to as water dispersible granules (English code WDG). In fact, is the difference between processing methods, DF is wet grinding, granulation, WDG is dry crushing, granulation.
2, dry suspension agent manufacturing process:
Ingredients + Additives + Fillers + Water - Ingredients - Homogenization - Coarse Milling - Fine Mills - Pressure Spray Drying - Testing - Packaging
That is, the original drug, additives, fillers, water added to the ingredients tank, stir evenly, and then high-speed shearing machine for coarse crushing, and then into the two-stage sand mill fine grinding, grinding after adding granulation additives into Pressure spray drying tower drying, granulation, detection spray drying tower at the bottom of the finished product, qualified into the storage tank, to be packaged after the factory sales.

3, the characteristics of dry suspension agent:
Advantages:
A, diluted natural fine particles of up to 1,5 microns, significantly better than the dry 10,40 microns. The fineness of the apparent improvement will be manifested in the increase in the rate of suspension, dispersion and efficacy.
1, in the water can quickly disintegrate, dispersibility and suspension of good. 2, liquid particles very subtle, can be attached to the surface of the crop, the formation of dense protective film, supplemented by a good adhesive, can increase the adhesion performance, resistance to rain erosion. 3, the proportion of liquid chisel size distribution is reasonable, both to ensure the effectiveness of the agent and effectiveness, and protective agents and crop surface can be fully in full contact with the active ingredients evenly play a role in the leaves of each drug can be more uniform , To ensure a longer duration, improve efficacy. 4, good security, not easy to produce injury, even in the flowering can also be used.
B, the production workshop environment greatly improved, wet crushing, drying, granulation basically no dust hazards, fundamentally changed the dry crushing, granulation, drying process "products look good, the workshop can not see" situation.
C, due to wet process materials in the pipeline transport, can achieve continuous production, and thus can achieve automatic control, equipment level can be greatly improved.
D, drying process is spray drying, without squeezing, water evaporation in a very short time, the particles fluffy, so the number of additives and the quality requirements to reduce, you can save the cost of additives.
