Detailed explanation-1: -Mechanical separation of solid contaminants from oil systems (fuel and lubricating) is achieved by the use of filters and strainers. A strainer is usually a coarse filter to remove the larger contaminating particles. Both are arranged as full flow units, usually mounted in pairs (duplex) with one as a standby.
Detailed explanation-2: -Most simple examples of filterable mixtures are sand and water, dirt and water, etc.
Detailed explanation-3: -FILTRATION. When the substances in a mixture have different particle sizes, they are separated by filtration. The mixture is poured through a sieve or filter. The smaller particles slip through the holes, but the larger particles do not.
Detailed explanation-4: -Magnetic separation means separating mixtures of two solids with one part which has magnetic properties. It is based on the difference in magnetic and non-magnetic substances. In the mixture of iron and sulphur, iron particles get attracted to the magnet and separates from non-magnetic substances.
