High-quality recycling requires sorting of plastics according to density. Density separation is achieved by means of an improved design and several paddle rollers and water to achieve a particularly high separation efficiency. This ensures that the plastics are sorted according to their density.
The separation of plastics according to density is an important step in the production of high-quality granulates from mixtures. Today, density separation with water is used for this purpose. Only the pure plastic is valuable for the processing industry. Due to its specific property profile, the used plastic generates high revenues on the markets for secondary raw materials.
Most of the separation containers offered on the market are incorrectly designed. Strong water currents overlay the density separation in the gravitational field. In addition, air bubbles adhering to the plastic ensure that the actually heavy particles float up. As a result, many plastics are not sorted correctly.
The hydrocyclones designed by Pla.to improved work with more than twenty times the acceleration due to gravity and thus achieve a very high degree of separation efficiency. Heavy and light materials leave the container separately.
Our density separation is particularly energy-efficient and requires little space, thus enabling economical recycling.
