Plastic laundry

The plastic washing unit is a key component in any recycling plant that processes post-consumer plastic or recovered industrial material. This equipment ensures the removal of impurities, organic residues, labels, adhesives and contaminants, thereby improving the quality of the recycled material and increasing its market value.

This machinery prepares the plastic for subsequent granulation, extrusion or recycling, reducing incidents in subsequent processes and improving the plant’s overall performance. High-efficiency plastic washing plants are essential for processing materials such as HDPE, PET, PP, ABS and polyethylene film.

How does a industrial plastic washing machine?

These machines are designed to perform an intensive cleaning process using friction, agitation, and density separation. Their purpose is to remove surface dirt and contaminants adhering to shredded or granulated plastic.

Furthermore, they help to reduce wear and tear on downstream machinery, thereby minimizing operational incidents and maintenance costs. This results in greater production continuity and a more efficient use of available resources.

The overall operation is structured in several phases:

1. Feeding the crushed material

The pre-processed plastic enters the washing system through a hopper or conveyor belt.

2. Washing by friction or agitation

Using blades, propellers or rotating systems, the material is subjected to a friction process that removes labels, organic remains and adhered particles.

3. Separation of impurities

Thanks to decantation or flotation systems, lighter or heavier contaminants are separated from clean plastic.

4. Preparation for drying

The washed material is directed to centrifuges or drying systems to reduce moisture before the granulation phase.

Large plastic washing plant: capacity and performance in the plant

These are pieces of equipment designed for high-production plants, capable of processing large volumes of material continuously.

Industrial plastic washers are designed to carry out an intensive cleaning process using friction, agitation and density separation. Their purpose is to remove surface dirt and contaminants adhering to shredded or granulated plastic.

The process is divided into four stages:

Feeding of the shredded material — The pre-processed plastic enters the system via a hopper or conveyor belt.
Friction or agitation washing — Using blades, propellers or rotating systems, the material is subjected to friction which removes labels, organic matter and adhering particles.
Separation of impurities — Using decanting or flotation systems, lighter or heavier contaminants are separated from the clean plastic.
Preparation for drying — The washed material is fed into centrifuges or drying systems to reduce its moisture content prior to the granulation stage.

In demanding industrial environments, capacity and performance are key factors.

A washing system must ensure:

High processing throughput

Optimized water consumption

Resistance to wear from friction

Easy maintenance

A well-sized plastic sink allows for:

Improve the quality of recycled plastic

Reduce reprocessing costs

Improve the overall efficiency of the line

Increase the profitability of the plant
