Maximum capacity for these crushers is 20 t/h. If the dust crushers are placed consecutively, first the rotor crusher, then the roller crusher, a final product of 5 x 5 mm can be achieved from a maximum feed size of 300 mm. 

Slag crushers can be cooled by water, pressurized air or steam if it is required.
Slag roller crushers can for example be used in a copper smelter for crushing coarse dust which is built up in the Gas Cooling Chambers and Balloon Flue of PS Converters.
