Get a QuoteFrequently Asked Questions
1. What is the main purpose of a rigid plastic washing line?
The primary purpose is to take highly contaminated rigid plastic waste (like used drums, pipes, crates, or car bumpers) and transform it into clean, dry, high-quality plastic flakes. These flakes are then ready to be used in a pelletizing/granulating machine to produce new plastic pellets.
2. What types of rigid plastics can this line recycle?
This washing line is specifically designed for polyolefin plastics. It is highly effective for PP (polypropylene) and HDPE (high-density polyethylene). It can also process other rigid plastics such as ABS, PS, and more. It is not suitable for PET bottles, which require a different process.
3. How is this line different from a PET bottle washing line?
The key difference lies in the separation technology. This line uses a float-sink separation tank. PP and HDPE plastics have a density less than water, so they float. Contaminants like PET, stones, and metal sink to the bottom. This method is ineffective for PET bottles, which also sink and require different separation techniques like air classifiers.
4. How clean and dry are the final plastic flakes?
The system is designed to produce exceptionally clean flakes. The multi-stage washing process, including high-speed friction washers and optional hot washers, removes dirt, sand, labels, and glue. The final dewatering and thermal drying stages ensure a final moisture level of less than 1%, which is crucial for high-quality pelletizing.
5. Can this washing line be customized for my specific needs?
Yes, absolutely. Each washing line is custom-built based on your requirements. We consider the type of plastic you're processing, the level and type of contamination, your desired capacity (kg/hr), and your final quality standards to design a solution that is perfect for your operation.
6. What information should I provide to get an accurate quote?
To give you the most accurate quote, please provide us with: 1) The primary type of plastic you will be recycling. 2) The source and type of contamination (e.g., post-consumer crates with labels, industrial pipes with oil). 3) Your required capacity in kg/hr. 4) Any specific requirements for the final product.
