Efficient Trommel Machines for Plastic Recycling

When it comes to plastic recycling, separating contaminants from valuable materials is critical for ensuring a high-quality end product. This is where trommel machines come into play. These slow-rotating, cylindrical separation machines are essential in plastic recycling plants and larger Material Recovery Facilities (MRFs) dealing with municipal waste. Despite their leisurely pace, trommels are incredibly effective at filtering out smaller contaminants from recycling streams, making them a key component in the recycling process.

Trommel in Plastic Recycling Machines

Trommel machines are vital in the plastic recycling industry, where the quality of the recycled material depends on how efficiently contaminants are removed. Here, we will explore the working principle, features, and technical specifications of trommels to understand why they are indispensable in modern recycling operations.

How Trommel Machines Work

At the heart of a trommel is a large, cylindrical mesh screen tunnel that rotates at a speed of 6 to 10 rotations per minute. The rotating cylinder is equipped with flaps inside that serve two primary purposes:

1. Flipping the Feed Stock: The flaps continuously flip the feed stock, ensuring that all materials are exposed to the mesh screen for effective separation.
2. Guiding Forward Motion: These flaps also help guide the feed stock through the tunnel, which is typically tilted at a slight angle.

As the feed stock moves through the trommel, smaller contaminants like broken glass pass through the mesh screen and are collected. The remaining materials, which are larger than the holes in the mesh screen, continue to move forward to the next stage of recycling. This process ensures that only clean and usable plastic materials proceed to further processing, improving the overall quality of the recycled product.

Key Features of Trommel Machines

Our trommel machines are designed to be robust and adaptable, making them suitable for various recycling applications. Below are some of the key features:

• Standard Trommel Dimensions: We offer a standard model with a diameter of 2000mm and a length of 1200mm. However, custom sizes are available upon request to meet specific operational needs.
• Automatic Brush Units: To keep the mesh filters clean and functioning optimally, our trommels come equipped with automatic brush units. This reduces downtime and maintenance efforts.
• Drive Design: Depending on the application, our trommels can be equipped with either a two-wheel or four-wheel drive design. This flexibility ensures smooth operation in different environments.
• Control Options: Our trommels include frequency and synchronization controls, allowing operators to fine-tune the machine’s performance for different types of feed stock.
• CE Certification: All our trommels meet the CE certification standards, ensuring compliance with safety and environmental regulations.
