The crusher design can be adapted for wet or dry crushing of slag. DVZ crushers are roller-toothed crushers for primary crushing of slag with a maximum input material size of up to 25-60 mm. DVR crushers are equipped with smooth or grooved rollers for crushing final product of up to 5 mm in size. They can also be used for economical crushing of coal, burnt lime, artificial fertilizers, and de-icing salts.
