Increase capacity and sieving efficiency when separating powders and granules with innovative cascade system

The ‘Cascade System’ for vibratory separators was designed to accurately sieve powders on a much larger screen area, removing the need to invest in more expensive, larger diameter machines to obtain a higher throughput.

The system can be mounted to existing grading machines in the same manner as a standard sieve deck and can be fitted to most round separators of 48” and 60” diameters.

The system is based on two screens of the same mesh size, mounted one above the other, the upper screen being slightly smaller in diameter. Material is fed to the upper screen and either passes through the mesh to be channeled to the discharge spout, or flows over the edge onto the screen below where it has another chance to be screened. Particles of the specified size passing though the lower screen are discharged in the normal manner. All oversized particles are discharged from the lower screen.

The two-phase separation process increases mesh area significantly, compared to a standard separator of the same diameter, raising capacity by up to 70%.

The Russell Finex Cascade System is particularly effective where the particle size of the powder being screened is very close to the aperture size of the mesh. In this situation it is difficult for the particles to pass through the mesh and therefore having the extra mesh area increases the throughput significantly.

Grading sievesare designed to accurately grade, scalp or size wet and dry materials, achieving up to five fractions in one operation. Russell Finex separators are available in four sizes: 30″, 40″, 48″ and 60″ diameter, and benefit from major advances in separation technology, providing large improvements in sieving accuracy, capacity, noise levels and upgradeability compared with traditional spring suspension separators.
