— The primary crushing stage consists of one gyratory crusher. The product of the primary crusher is classified by double deck screens (64 and 32 mm). The material retained in 32 mm feeds two secondary cone crushers. The product from the secondary crushers is discharged on the same conveyor belt of the product of three tertiary crushers.
