Mechanical Separation topics include: sedimentation theory, sedimentation equipment, centrifugation and its equipment. Mechanical separation is a process that separates components of a mixture based on their size and density differences. It can be used to separate solids from liquids, and is often the first step in recycling.  Mechanical separation techniques include:  Filtration, Sedimentation, Centrifugation, Removing housing, Skinning, Crushing, Shredding, Shearing, Sieving.  Mechanical separation can also refer to the process of dividing waste into different components using devices...
