Granulators are machines used to break down large materials into smaller, more manageable pieces. They are commonly used in industries such as recycling, plastics, and pharmaceuticals to process materials like plastic waste, rubber, and metal scraps. By reducing the size of these materials, granulators make it easier to reuse or recycle them. The granulation process typically involves cutting or grinding the material into uniform particles. This is achieved through various methods, including the use of rotating blades or knives. The resulting granules can then be used in manufacturing processes or as raw materials for other applications, promoting sustainability and efficiency in production.
