A double shaft shredder for scrap metal is a powerful machine used in scrap metal recycling to reduce large metal objects into smaller, more manageable pieces. It is specifically designed to handle the shredding of various types of metal, such as steel, aluminum, copper, and iron. Here's an overview of how a double shaft shredder for scrap metal works:

Feeding: The scrap metal objects, which can include car bodies, appliances, structural components, or metal scraps, are loaded into the shredder's feeding hopper. The feeding process can be manual or automated, depending on the shredder design and setup.

Shredding Mechanism: A double shaft shredder is equipped with two counter-rotating shafts that contain multiple sharp blades or hammers. These shafts are typically driven by electric motors at high torque, allowing them to effectively tear apart the metal objects. The blades or hammers are strategically positioned along the shafts to ensure thorough shredding.

Crushing and Size Reduction: As the scrap metal enters the shredder, the rotating blades or hammers grab hold of the material and tear it apart. The high-speed rotation and cutting action of the blades result in the metal being crushed and broken into smaller pieces.

Screening and Sorting: After the initial shredding process, the shredded metal pieces are typically passed through a screen or sorting system. This screen helps separate the metal fragments into different sizes or fractions. This step can be useful for further processing or separating different types of metals for recycling purposes.

Separation of Non-metallic Material: Depending on the specific requirements, the shredded metal may further undergo a separation process to remove non-metallic materials, such as plastic, rubber, or insulation. This can involve techniques like magnetic separation, eddy current separation, or air separation systems to isolate and remove non-metallic contaminants.

Collection and Recycling: Once the shredding process is complete, the shredded metal pieces are collected and prepared for further processing or recycling. The shredded metal can be transported to a scrap metal recycling facility, where it is melted down and used as raw material in the production of new metal products.
