A laboratory roll crusher for medium and fine crushing with adjustable gap, producing a uniform product with a high proportion of fines-to-powder — the controlled size reduction stage between jaw crushing and grinding.
Typical applications
Controlled size reduction before splittingFeed prep for dry magnetic separationMinimal over-crushing of valuable mineralsPilot line secondary crushing
Why this design
- Roll crushing breaks along grain boundaries — less over-crushing of the mineral you are trying to recover
- Uniform product makes downstream test results reproducible
- Gap-adjustable: several product sizes from one machine
