Mass Weight Density or Specific Gravity of Bulk Materials

The specific gravity of all other materials are compared to water as a fraction heavier or lighter density For example ammonium nitrate has a specific gravity sg of 0.73 while dry ammonium sulphate has a sg of 1.13 1130 kilograms/cubic metre see table below As specific gravity is just a comparison it can be applied across any units The density of pure water is also 62.4 lbs/cu.ft

Mechanical screening

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.
