DANGER!
Explosion hazard!
– When grinding oxidizable substances, e.g. metals or

coal, there is a risk of spontaneous combustion (dust

explosion) if the share of fine particles exceeds a cer-

tain percentage. When grinding these kinds of sub-

stances, special safety measures must be taken and the

work must be supervised from a specialist.

– The high-speed rotor mill is not explosion protected

and is not designed to grind explosive materials.

2.6 Hazardous points

n

Because the grinding container operates uncovered for better heat

conduction, touching the grinding bowl or the fixture during the

grinding process results in a risk of impact. Bear this in mind in par-

ticular when starting the operation. Always turn the main switch to

"Off" before working on the grinding bowl clamp to prevent the start

button from being unintentionally activated.

n

Crushing hazard when clamping the grinding bowl.
