The required product size was less than 162 mm. manufacturers data indicated that the nearest size of gyratory crusher would be 1370 x 1880 mm with a cone angle of 18.

Secondary Crushers – Cone Crusher. The most common type of secondary crusher is the cone crusher. A cone crusher is very similar to the gyratory but has a much shorter spindle with a larger diameter crushing surface relative to its the vertical dimension. The eccentric motion of the inner crushing cone is similar to that of the gyratory crusher.

The primary crushing stage is the first stage of the crushing process. This is where the bulk of the rocks or ore are crushed to make them manageable in the next crushing stages. The primary aim of the primary crushing is to produce a product that can be moved easily by conveyors or feeders to the next step of the crushing.
