Zinc-based derivatives such as zinc oxide, zinc borate, zinc stearate, zinc carbonate, and zinc sulfate are widely used in rubber, plastics, pharma, agrochemicals, and coatings. These powders are often fine, lightweight, and prone to agglomeration, requiring efficient, contamination-free screening to maintain product quality and flowability. Our vibro separators—especially with ultrasonic screening technology—ensure high-throughput, fine mesh separation with minimal blinding and consistent particle control.
