What does a powder sieve machine do?

A powder sieve machine reconditions recovered powder coating material from the cyclone/filter system — vibrating it through a fine mesh screen to break up agglomerates, remove debris, and ensure only consistent particle-size powder is recirculated to the gun. This maintains coating quality while recovering maximum powder value.

Why is sieving important in a powder coating line?

Without sieving, agglomerated or contaminated recovered powder can cause coating defects — rough texture, fish eyes, or thin spots. Sieving ensures recovered powder meets the same quality standard as virgin material before reuse.

Is the OptiFinish sieve machine compatible with GEMA OptiCentre?

Yes. The PS Vibratory Sieve Machine integrates into the powder recovery and feed circuit alongside GEMA OptiCentre OC08 powder management systems and standalone cyclone recovery units — all available from OptiFinish.

PS Vibratory Sieve Machine

Recovered powder. Ready to reuse.

A vibratory sieve unit developed in-house by OptiFinish — processing recovered powder from the cyclone to remove agglomerates, lumps, and foreign particles before it re-enters the hopper. Clean powder. Consistent quality. No manual sieve operation.

Why this product

Recovered powder fed back unprocessed causes defects.

Powder recovered from the cyclone and bag filter contains agglomerates, lumps, and contamination from the booth environment. Fed directly back to the hopper, these particles cause pinholes, surface defects, and nozzle blockages. The PS Vibratory Sieve Machine processes every batch of recovered powder before it re-enters the supply chain.

Vibratory sieving mechanism continuously separates powder without degrading particles
Removes agglomerates, lumps, and foreign particles before powder reaches the gun hopper
Colour-change ready — fast manual cleaning between powder batches with minimal cross-contamination risk
Accessible internal components for quick mesh replacement without specialist tooling
Low maintenance design — built for continuous operation across production shifts
Designed and manufactured at OptiFinish's Greater Noida R&D facility

How it works

Recover, sieve, reuse

Recovered powder entry

Powder recovered from the cyclone separator is directed into the PS Vibratory Sieve Machine. The unit sits inline between the cyclone output and the hopper return — processing every batch of recovered powder before it re-enters the gun supply.
