Crushing and recycling magnesium: Safe processing of magnesium scrap

Comminution of magnesium scrap in the laboratory, pilot plant and recycling

Magnesium is a very light metal used in many technical applications. When crushing magnesium scrap, the focus is not only on the feed size and target particle size, but above all on a reliably controlled process. Therefore, the selection of suitable machinery, controlled process management, and appropriate measures for dust and ignition source control are crucial for processing. The existing application specifies a feed size of 120 mm, a target particle size of 1,5 mm, a throughput of 500 kg/h, and a hammer mill as the appropriate machine.

FAQ on magnesium grinding

Magnesium is a very light metal with the symbol Mg and an important material for lightweight construction, alloys and recycling.

Magnesium scrap is inspected, pre-crushed if necessary, crushed in a controlled manner, classified and, if required, divided into samples.

The hammer mill is suitable for the existing application. The exact selection depends on the particle size, target fraction, and safety requirements.

For the current application, a target particle size of approximately 1,5 mm is specified.

Fine magnesium particles and magnesium dust can pose a fire and explosion hazard. Therefore, safe process control is crucial.

Important factors include feed size, target particle size, throughput, dust control and avoidance of ignition sources.

Sample splitting ensures representative laboratory samples and reproducible results in analysis and quality assurance.
