Committed To Quality, Committed To You
In many industries which include plastics, coatings, additive manufacturing, adhesives, and molding we see that resin powders play a key role. But achieving a consistent, fine, and contamination-free particle size is one of the toughest steps in resin processing. Resin powders sometimes act unfavourably—they might be brittle when going through cryogenic grinding, sticky under normal conditions, attract electrostatic charges, or form soft agglomerates easily.
In order to present high quality end products manufacturers, turn to very efficient screening systems which at the same time will provide for the same particle size distribution and also to prevent screen blockages and unintended down time. This is where centrifugal sifters become a transformative technology—offering a superior way to classify, de-agglomerate, and quality-check resin powders with minimal maintenance.
Resin powders tend to form soft agglomerates during grinding or cooling. These clumps can choke traditional vibratory sieves, reduce sieving efficiency, and compromise product quality.
Many resins generate static charge, especially when finely ground. Charged particles cling to mesh surfaces, causing screen blinding and dramatically reducing throughput.
When cryogenic grinding is performed, resin particles are highly brittle which results in higher probabilities of damaging the screen. At normal temperature, they can stick and join together.
The traditional sieves find it difficult to handle fine resin powders (<150 micron). Blinding limits the open screen space and requires constant interruptions to clean it.
Resin manufacturers must sustain high volumes without sacrificing accuracy. Most conventional sieve designs slow down under load or require frequent interventions.
Since resin powder is applied in high-performance, it should not contain any foreign substances. This needs a dust free, hygienic screening place which is closed.
Centrifugal sifters are designed to cope with fine, fragile, or sticky powders that are usually very difficult for conventional vibratory screens. Their internal design offers multiple advantages for resin powder processing.
A rotor paddle system forces material through a rotating cylindrical screen and extrudes soft lumps breaking them without destroying fragile resin agents.
Instead of particles sitting on the mesh surface (as in vibratory screens), centrifugal sifters create outward airflow and centrifugal force:
Because the paddles do not aggressively impact the screen surface:
Thus, centrifugal sifters are perfect for cryogenically ground resin powders.
The design of the equipment permits:
This ensures 24/7 industrial-scale productivity.
Resin powders are extremely lightweight dusting is a big issue. Centrifugal sifters come with:
This ensures contamination-free and operator-safe handling.

Galaxy Sivtek provides depending on the resin behavior:
This guarantees optimal throughput and least damage of products.
Optional anti-blinding arrangements ensure consistent performance, especially with fine resin powders.
Galaxy Sivtek sifter construction embodies:
Perfect for industries that prioritize hygiene and contamination-free processes.
Galaxy Sivtek machines work efficiently for a long time with the different resin powder types ranging from PE, PP, PU to research level engineering resins like PEEK, nylon, PVC, and coating resins.
The screening of resin powder is a tough task with the problems like agglomeration, static charge, temperature sensitivity, and the precipitating problem of the screens all the time. Centrifugal sifters lend a hand in such a scenario as they easily, by means of their controlled centrifugal force, de-agglomerate, classify and perform a quality check of resin powders which keeps the throughput and purity safe.
With Galaxy Sivtek’s engineered centrifugal sifters, manufacturers benefit from:
Consistent particle size
Galaxy Sivtek ensures that resin processors achieve a stable, uniform, and high-quality powder, ready for any downstream application.
