4. SIZE REDUCTION
Crushers do the heavy work of breaking large pieces of solids into smaller lumps. Primary crushers are run on materials out of mine the size of which may reach more than one meter and breaking it into 150 – 300 mm lumps. A secondary crusher reduces those lumps to particles in the size range of 5 – 10 mm. Grinders reduce crushed feed to powder.
