    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.

    explain problems associated with screens in ore crushing

    Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

    Screening is carried out at various stages in the crushing process. Screens are basically box frames into which sheets of screen meshes of the required apertures are inserted, clamped and tensioned. Screens are usually "multi-deck", i.e., two or more screen meshes are stacked vertically within the screen frame.

    Sample Reduction SGS

    Sample Crushing. SGS laboratory staff most commonly use a jaw crusher as the primary crushing tool. These crushers can accommodate chunks up to 15 cm and can reduce them in size until 80% of the sample passes through a 2 mm screen. Staff then use ring and puck mills to prepare a smaller particle size if required for sample pulverizing.
