Jet Mill
The Open Manifold Design (OMD) Micronizer offers a solution to herbicide, pesticide, and insecticide manufacturers that require 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 mill can typically produce particle-size distributions between 1 and 20 µm.

Pulse-Jet Filters
These pulse-jet air filters are custom built for efficient, economical operation in demanding applications. Particulate-laden air is directed toward a deflector, which causes heavier particles to fall directly into the collection hopper. Lighter airborne particles collect on the outside surfaces of the internal bag filters. Filtered air exits the unit. Sequential bursts of compressed air dislodge dust on the surfaces of the bag filters so that the dust also falls into the hopper.
