RETSCH jaw crushers are used for the rapid, gentle crushing and pre-crushing of medium-hard, hard, brittle and tough materials. Many unique details ensure safe and convenient operation and guarantee representative sample preparation every time.

RETSCH offers a range of suitable mills for the pulverization of medium-hard, hard, brittle and tough sample materials:
 

Ball mills Mortar grinders Vibratory disc mills
RETSCH ball mills and mixer mills are particularly suitable for pulverizing hard and brittle materials with a maximum feed size of 6 to 10 mm. They can achieve grind sizes down to 0.001 mm. RETSCH mortar grinders are used to grind soft, hard and brittle materials to a fineness of approx. 0.01 mm. The maximum feed size is 8 mm. RETSCH vibratory disc mills for medium-hard, brittle and hardtough materials with feed sizes up to 15 mm achieve grind sizes down to 0.04 mm. This makes them ideally suited for sample preparation to spectral analyses. RETSCH disc mills achieve grind sizes of approx. 0.1 mm.
