WIMA Density Separator – HDS-Series.

HDS Series
Your Solution for Precise Hydro-Density Separation

Our HDS series provides effective solutions for water-based separation of heavy and light materials, with a clear focus on reliability and precision. The functional principle of our HDS models proves to be a versatile solution in the field of secondary raw materials, successfully addressing specific challenges.

Operating Principle:

The HDS is a density separator that utilizes the different densities of materials to separate them from each other. Water, with its density of about 1 g/cm³, forms an ideal basis for separation. Material with a density greater than 1 g/cm³ reliably sinks, while material with a lower density floats on the water surface.

To further optimize this separation, the HDS generates a targeted upflow. This mechanism ensures that particles with higher density either sink when their sinking speed is greater than the upflow speed, or float when the upflow speed prevails. This approach ensures precise and effective separation of materials, which is often a challenge in conventional processes.
