Learn how a customized plastic sorting line improves PET recycling by increasing material purity, reducing contamination, and maximizing the value of recycled plastics. Discover how Amstar's advanced plastic recycling machines deliver efficient, high-performance sorting solutions.

In modern plastic recycling plants, even a small amount of aluminum, copper, or metal contamination can significantly reduce the value of recycled plastic flakes and pellets.

In a modern plastic recycling machine, the belt conveyor plays a vital role in transporting materials between shredding, crushing, washing, drying, and pelletizing processes.

In the plastic recycling industry, blade sharpness directly affects machine performance, production efficiency, material quality, and operating costs. Whether used in plastic granulators, crushers, or shredders, worn or dull blades can lead to excessive dust, unstable output size, higher energy consumption, and reduced production capacity.

In plastic recycling operations, downtime is expensive. For many crushers and shredders, blade replacement is one of the most labor-intensive maintenance tasks — especially when dealing with heavy rotor knives, tight installation spaces, and repeated alignment adjustments.

Transform plastic waste into profit with advanced recycling machines that convert discarded materials into high-quality reusable pellets. These systems reduce costs, improve efficiency, and support your move toward a more sustainable, circular business model.

The plastic sorting line is an essential piece of equipment for processing a wide range of plastic materials, including various types of hard plastics such as PP, PE, PS, PVC, and ABS.

A centrifugal dryer in plastic recycling does more than remove moisture—it stabilizes material flow, improves extrusion consistency, and boosts overall line efficiency. By reducing water content early in the process, it lowers energy demand for thermal drying and minimizes defects like bubbles in pellets.

After ferrous metals are removed, the remaining mixed material (plastics + aluminum + copper) enters the eddy current separation stage, which is critical for value recovery.

The Dissolved Air Flotation (DAF) system is a highly efficient solid-liquid separation technology widely used in industrial wastewater treatment. It works by generating a large number of microbubbles (10–30 μm) that attach to suspended solids, oil, and grease.
