Pesticides
Hosokawa supplies complete systems for the manufacture of insect sprays, dusts or granules. The Hosokawa/Alpine fine impact mill UPZ is used for this task. The particle sizes demanded for insect sprays are achieved with the Hosokawa/Alpine fluidized bed opposed jet mill AFG. These mills set new trends in the production of pesticides.
System schematic
Formulation system for the universal production of dusts and sprays with different end-product fineness values and concentrations of active ingredients.
System classified as per ATEX 94/9 EC:
Pressure-shock-proof section inside: zone 20
Mixer inside: zone NEX, N2-blanketing
Mixer outside: zone 22
Control cabinet: zone NEX
The end products range between 10 and 40 µm in size and are free from oversized particles. The products are extremely homogeneous and display excellent suspension properties. The problem commonly encountered when mechanical impact mills are used — i.e., the spalling-off of deposits — is not issue with fluidized bed opposed jet mills. This means that elaborate and expensive safety screening steps are no longer required in modern pesticides production systems configured with fluidized bed opposed jet mills. The AFG can grind complex pesticides formulations with active ingredient contents of up to 80%. The temperature rise in the AFG during grinding is negligible, meaning that even products with low melting points can be processed without any problem. In special cases, it is even possible to grind pure active ingredients with the AFG. This type of processing has the great advantage that the carrier materials, which are already of end-product fineness, do not need to be passed through the mill system, but are rather mixed in at the end of the process.
The impact mills that were often employed in the past for grinding pesticides are much less suitable due to the temperature rise during grinding.
Fluidized Bed Opposed Jet Mill AFG
A machine with a horizontal nozzle arrangement—the AFG standard system for the production of pesticides.
Fluidized Bed Opposed Jet Mill AFG-R
A machine with a 3-D nozzle arrangement and an additional nozzle at the bottom.
Advantage: practically no residues remain in the grinding chamber when emptying the machine.
experimental verification
Before investing in new equipment, please conduct tests on the materials to be used at the Hosokawa Test and Process Development Center based on actual production conditions. Our experienced experts will assist you in determining the most effective mixing, granulation, or drying processes, helping you transition from laboratory trials to a comprehensive production testing phase. Whether you need to test the performance of a single machine or evaluate the entire production line, we can provide tailored testing services and process optimization solutions to ensure reliable system operation and excellent performance.
