  • Mechanical screening - Wikipedia

    Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.. A method of separating solid particles according to size alone is called screening.
