Industrial sifters play a crucial role in powder processing worldwide, ensuring product quality, removing contaminants, and meeting safety standards. Selecting the right screen and machine depends on several factors, including particle size and distribution, product sensitivity, moisture content, throughput rate, and ATEX compliance.

Two main screening technologies are commonly used. Centrifugal sifters, or rotary sieves, employ centrifugal force to propel particles through a cylindrical screen. Internal paddles rotate the material, enabling gentle yet high-throughput screening. They are particularly effective for fine powders, as they also deagglomerate materials while removing foreign bodies, ensuring consistent product quality.

Vibrating sieves, by contrast, use mechanical vibrations to separate smaller particles from oversized material. Their precise classification capabilities make them ideal for fine powders, while their compact design and straightforward maintenance have led to widespread adoption across many industries.

Gericke’s GS centrifugal sifter has proven especially effective in the food sector, contributing significantly to safety by reliably removing foreign bodies. With more than 50 years of expertise, Gericke has refined its designs through testing and customer collaboration. Its patented perforated plate geometry balances throughput with oversize separation while reducing wear and changeover times. The result is efficient, consistent performance that supports high-quality, reliable powder handling worldwide.
