Single-Shaft Shredder for Extruder Head Waste

A single-shaft shredder is an essential piece of equipment designed to efficiently handle the shredding of extruder head waste. This machine is built with a robust structure that includes a motor, a reducer with rigid gears, a rotary shaft, imported rotary knives, fixed knives, a sturdy frame, a working platform, a hydraulic ram, and an independent electrical control cabinet.

Introduction

The fixed knives are securely mounted on the frame behind the solid rotary shaft, where they work in tandem with the moving knives. These moving knives are engineered with a unique four-angle design, allowing for multiple uses before they need to be replaced. When one angle becomes blunt, the knife can simply be rotated to a new angle, maximizing the knife’s lifespan and reducing maintenance costs. Additionally, the knives are fastened with screws, making them easy to remove and replace during maintenance.

The single-shaft shredder is controlled via an independent electrical cabinet equipped with a state-of-the-art PLC system. This advanced control system provides start, stop, and reverse functions, ensuring smooth operation. Furthermore, the shredder features an automatic overload return mechanism, which safeguards the working components from potential damage due to overload, enhancing the machine’s durability and reliability.

This single-shaft shredder is designed not only for optimal performance but also for ease of use and maintenance, making it an excellent choice for recycling operations dealing with extruder head waste.
