Spray Nozzle Droplet Size Categories
Spray nozzles have three main droplet sizes: fine, medium, and coarse. Each size has its own benefits, making the right choice key for the job. Let’s look at what makes each size special and when to use them.
Fine Droplets
Fine droplets are between 150 to 250 microns big. They’re perfect for getting herbicides and insecticides to where they need to go. These small droplets cover well and soak into surfaces deeply. But, they can easily blow away in the wind, so be careful where you use them.
Medium Droplets
Medium droplets are 250 to 400 microns. They’re a good all-around choice for many uses, like with a spray nozzle flow rate calculator or turbo drop nozzle chart. They go deep into surfaces and don’t blow away easily, making them great for many farming and gardening tasks.
Coarse Droplets
Coarse droplets are 400 to 600 microns big. They’re made for reducing wind-borne drift and covering big areas. These large droplets stay put in windy conditions, which is good near sensitive spots. But, they might not spread out as much as smaller droplets. The lechler spray nozzle catalogue (pdf) has more info on coarse droplets.
Knowing the differences between spray nozzle droplet sizes helps pick the best one for the job. It ensures the spray works well, covers the area right, and is safe.
Spray nozzle droplet size and Application Efficiency
The size of spray nozzle droplets is key to how well an application works. Droplets smaller than 200 microns cover better and go deeper, making sure the spray spreads evenly. Droplets over 400 microns don’t drift much but might not reach where you want them to.
Knowing how droplet size affects your spray’s efficiency is crucial. Smaller droplets bring big benefits:
- Better coverage and sticking to the target surface
- Deeper penetration into thick foliage or hard spots
- Less runoff and waste
Larger droplets also have their perks:
- Less chance of drift, so less spray goes where you don’t want it
- Sticks better to the target in windy conditions
- Less evaporation during spraying
The best droplet size depends on your specific needs. Consider the crop, weather, and spray solution’s nature. Choosing the right nozzle and settings helps balance coverage, sticking, and drift control for top application efficiency.
