Mechanical Process Engineering

The mechanical process technology is a branch of chemical engineering and deals with the conversion of material systems by predominantly mechanical influences.

Mechanically influenceable systems are converted using methods of mechanical process engineering. Their basic operations include:

• the shift in the particle size range towards smaller sizes ( crushing , atomizing liquids)
• the shift in the particle size range towards larger sizes ( agglomeration )
• the splitting of a disperse system into two disperse systems of different composition ( separation , sieving )
• the merging of at least two disperse systems of different composition into one disperse system ( mixing )
• the storage (for example in silos ) and conveying of solid matter systems, even if there are usually no changes to the system

Although phase boundaries are not usually overcome, the processes can be very energy-intensive. For example, four percent of the world's electricity demand is attributed to comminution processes (one percent of which is used for cement production ).
