The Open Manifold Design (OMD) Micronizer offers a solution to the herbicide, pesticide, and insecticide manufacturers requiring flexibility for the size reduction of multiple products. The OMD eliminates any hidden areas and allows the mill to be completely disassembled for cleaning. Having access to all internal areas allows the user to switch products without the risk of contamination and reduces turnaround time between the different powders. The unit can typically produce particle size distributions between 1 and 20 microns.
The unit employs compressed air or gas to produce particles less than one micron. Precisely aligned jets create a vortex. Material is fed into this vortex along an engineered tangent circle and accelerates. High-speed rotation subjects material to particle-on-particle impact, creating increasingly smaller fines. While centrifugal force drives large particles toward the perimeter, fine particles move toward the center where they exit through the vortex finder.
