MECHANICAL PROCESSES
Processec Engineering is the science of material transformation. Mechanical processes engineering involves the changes in material properties and composition due to mechanical effects.
* Separation Methods ;- Classifying and sorting
Classification is a mechanical separation method for solid compounds. It utilises either, the geometric features size or the setting velocity of the individual practical for the separation processes.
Sorting is a mechanical separation processes in which solid compound containing different materials characteristics is divided into fraction with the same material characteristics.
* Separation method ;- Separation in a gravity field
Mechanicals processes engineering in many cases utilises gravity to separate different phase. Gravity can be used to separate a solid phases off from a fluid.
As well as gravity, centrifugal force can also be use
* Separation method ;- Separation in a centrifugal force field
As well as gravity, centrifugal force can also be used as the driving force for phase separation processes. The centrifugal force can be generated either by rotating vessels.
* Separation method ;- Filtration
During filtration, solid particles are separated off by a filter medium from a flowing suspension. Suspensions contain insoluble solids finely distributed in a liquid. Usable filter media are sieves, cloths, papers or bulk solids.
* Comminution ;-
Comminution alters the particle size and shape and the surfaces of solids. Virtually all solids must be comminuted when being mined or processed.
