Dry cleaning is a particularly environmentally friendly method of cleaning used plastics. Without the use of fresh water, dirt such as paper labels and food residues are defibered by high acceleration and impact forces. While the cleaned plastic is sucked out of the process, the centrifuged residues leave the cleaner in a separate stream. The process works continuously and allows high throughputs.
The continuous process with high throughputs is applicable to all thermoplastics such as LDPE, HDPE, PP, PET, PA, HIPS and many more
For stubborn stains we offer an ideal unit with the friction washer and the intensive washer. With friction and water the plastic waste is cleaned in two steps. The friction washer allows water and plastic waste to circulate, soaks the waste and dissolves dirt. In the intensive washer a thorough post-cleaning and mechanical dewatering takes place.
Friction and intensive washers – A perfect combination of complementary cleaning machines.
For drying after washing, our High-Spin Dryer works with high rotation, a long rotor and many beaters. Especially thin-walled films can be dewatered very well. The internal friction loosens last dirt. These are removed by the automatic cleaning system with the spun-off water.
For further processing, the thermal drying system takes over the moisture reduction, especially of very thin films. A mixing of hot air and wet plastic in our centrifuge enables extensive drying. By using a heat exchanger, the combustion gases do not come into contact with the plastic. These so-called indirect hot air generators offer high fire safety.
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.
High-quality recycling requires sorting of plastics by density. Density separation takes place in a hydrocyclone with 22 times the acceleration due to gravity. The process ensures a particularly high degree of separation efficiency and, as a result, a single-grade plastic.
