Knife mills are specialised laboratory instruments designed for the rapid and efficient size reduction of various materials, including plastics, textiles, and food samples. These mills use sharp, rotating blades to cut and shear materials into smaller pieces, allowing for effective processing and preparation for analysis. Knife mills are particularly advantageous for soft, fibrous, or elastic materials, as they maintain sample integrity while achieving uniform particle sizes. Many models feature adjustable speed settings and interchangeable blades, providing flexibility for different sample types and desired particle sizes. Commonly used in industries such as food technology, pharmaceuticals, and materials science, knife mills enhance efficiency in sample preparation, ensuring consistent results in research and development.
