For very fine powders and fragile materials where traditional vibrating screens fall short, the SRD Machine Micronising Screen (Dancing Screen) offers the most optimised solution. The reason it is known as the ‘Dancing Screen’ in the industry is the machine’s three-dimensional, oscillating circular motion. This motion mimics the manual hand-sifting method, ensuring the product remains on the screen surface for a longer duration and is separated with maximum precision.

Working Principle

Unlike standard screens, dancing screens operate using a low-frequency, high-amplitude oscillating motion:

Three-Dimensional Oscillation: The machine performs an eccentric motion created by the combination of radial and tangential inclination. This allows the product to follow a spiral path from the centre of the screen outwards.

Adjustable Parameters: The inclination of the screen surface and the rotation speed can be precisely adjusted to determine the residence time of the material on the screen.

Gentle Screening: As the product is screened by ‘floating’ without being subjected to high-impact shocks, the particle structure is preserved, particularly in fragile and fine-grained materials.
