Dry cleaning is an environmentally friendly method of cleaning used plastics. Contaminants such as paper labels and leftover food are frayed by high acceleration and impact forces, without the use of fresh water. Through this process the clean plastic is extracted and the spun off residues leave in a separate stream. The process works continuously and allows high performance.
The process can be applied to all thermoplastics such as LDPE, HDPE, PP, PET, PA, HIPS and many more.
For stubborn contaminants, we offer the friction washer and the intensive washer as a single unit. The friction washer circulates the used plastic with water, thereby soaking and loosening the contaminants. A thorough post-cleaning and mechanical dewatering take place in the intensive washer.
Together the friction and intensive washer are the perfect combination.
For drying after washing, our high-spin dryer works with high rotation, a long rotor and many blades. Particularly thin-walled films can be dewatered well in this way. The internal friction dissolves any remaining contaminants and these are removed by the automatic cleaning system with the spun off water.
For further processing, the thermal drying system reduces moisture, especially of very thin plastic films. Mixing hot air and wet plastic in the centrifuge results in extensive drying. By using a heat exchanger, the combustion gases do not come into contact with the plastic. These “indirect hot air generators” offer a high level of fire safety.
High-quality recycling requires that plastics be sorted according to density. Pla.to systems separate with an improved design – high centrifugal forces with a hydrocyclone generate 22 times the acceleration due to gravity. This ensures exceptional separation precision.
High-quality recycling requires precisely separated plastic parts. In addition to density separation, we also offer zig zag air separation. The bulk weight determines the separation. Plastics with a low bulk density are sucked upwards, while heavy ground material falls downwards. An easy and inexpensive way to separate.
