Zinc occurs only in a combined state. The dominant zinc ores found in the earth’s crust is zinc blende (zinc sulphide or spharelite) ZnS, calamine ZnCO3 and Zincite, Zno. Zinc is commonly found in mineral deposits along with other base metals, such as copper and lead. Zinc deposits are broadly classified on the basis of how they are formed.

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.

For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7 × 1.7 = 78 cm.
