Different types of metals require varying amounts of force to break down, which is why high-grade blades and motors are essential. The adjustment of blade speed and feed rate can further enhance the operation, especially when dealing with diverse metal types.

After initial shredding, the material undergoes secondary reduction in the granulating chamber. This stage is highly controlled, as achieving the desired granule size is crucial for maximizing the value of the recycled material. The granulating process can vary in terms of speed and power, adapting to the specific characteristics of the metal being processed.

The following step involves the separation of metal granules from contaminants. The centrifugal separator utilizes high-speed rotation to create a centrifugal force that separates denser metal granules from lighter, unwanted materials. This not only helps achieve a higher quality product but also boosts the overall efficiency of the recycling process, as only suitable materials proceed to the final collection phase.

Monitoring and maintaining optimal operation is a continuous effort, with advanced metal granulators often equipped with automation technologies that allow for real-time data tracking.
