Improving the screening efficiency of powder coatings

Leading Chinese coatings manufacturer increases production rates using the Finex Separator™ with ultrasonic deblinding

With the rapid expansion of the Chinese industrial coatings industry, stricter environmental protection policies are being implemented. Not only has demand increased for environmentally-friendly coatings, manufacturers are also facing higher costs for raw materials and labor.

Seeking an innovative and efficient manufacturing solution, one leading coatings company contacted Russell Finex to optimize the screening of fine powder to remove contaminants caused by material that has polymerized during upstream processes. During this process, only powder of the correct particle size is passed through to the filling line, but manufacturers can run into issues with mesh blinding where finer powder can end up blocking the mesh screen.

Russell Vibrasonic® Deblinding System

One way coatings manufacturers often attempt to overcome this problem is through the use of nylon tapping balls or discs to assist with powder screening. However, this can lead to mesh damage and potentially contaminate the powder coatings as they wear, potentially harming the quality of the final product.

As a solution, the manufacturer implemented the Finex Separator™ and Russell Vibrasonic® Deblinding System into its production line. Through an ultrasonic frequency that breaks down surface tension, the Vibrasonic® Deblinding System eliminated mesh blinding while also allowing particle screening down to 20 microns. Production efficiency was further increased by reducing downtime needed to clean the mesh while minimizing the loss of fine powder.

The Finex Separator™ also allowed for significant improvements in sieving accuracy, capacity, noise levels and upgradeability compared with traditional spring suspension separators. This technology not only ensured consistent product quality, but improved production capacity while keeping costs low.
