What is the difference between shredding and granulating? 2011-12-12 12:15:59

Shredding and granulating are both size reduction processes used to break down materials into smaller pieces, but they differ in the final size and characteristics of the resulting particles.


  1. Particle Size: Shredding typically produces larger particle sizes compared to granulating. The shredded material may have irregular shapes and varying sizes.

  2. Purpose: Shredding is often employed to reduce the size of large objects or materials into smaller, manageable pieces. The goal is to break down materials into more manageable sizes for further processing or disposal.

  3. Applications: Shredding is commonly used for materials such as paper, cardboard, plastic, wood, and rubber. Industrial shredders are often used in recycling operations.

  4. Output: Shredded materials may have a wide range of particle sizes, and the output is usually a mix of differently sized pieces.


  1. Particle Size: Granulating results in smaller and more uniform particle sizes compared to shredding. The particles are often of a specific and controlled size.

  2. Purpose: Granulating is often used when a consistent and defined particle size is required. The process is suitable for producing granules that can be used in manufacturing or further processing.

  3. Applications: Granulation is common in the plastics industry, where plastic materials are processed into uniform granules for molding or extrusion. It is also used in pharmaceuticals and food processing.

  4. Output: The output of a granulator is typically more uniform, with particles of a specified size range. This consistency is important in applications where the size of the particles affects the end product's quality.

In summary, the primary difference between shredding and granulating lies in the size and uniformity of the final particles. Shredding is often used for coarse size reduction, breaking down large materials into smaller pieces, while granulating is employed when a more uniform and controlled particle size is required, suitable for specific manufacturing processes.
