  • Mechanical screening WikipediaOxidizing Liquids Solids Hazards OSH Answers

    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 recyclingcause combustible materials to burn spontaneously without the presence of obvious ignition sources such as a spark or flame ignition sources such as a spark or flame What happens when an oxidizing material comes in contact with a combustible substance largely depends on the chemical stability of the oxidizing material
