Principles of particle reduction. The most common method for obtaining a homogeneous sample is grinding of comminution. Grinding samples has many benefits for sample preparation since it increases homogeneity, increases surface area and decreases particle size which can improve extraction efficiency.
• Ball Mills or Ball-Medium Mills grind through impact of a grinding media such as balls, rods, etc. • Vibratory or Shaker Mills use high speed vibrations and grinding media to combine multiple grinding forces to reduce materials to fine powders. These mills can include grinding forces and media like balls, beads and grinding media.
