As the larger pieces of ore pebbles get comminuted in size, more large pieces are added. In the pebble mills, pebbles about 2 inches in size which are screened from the primary mill are used as grinding media. In grinders, larger rocks are used. Thus, grinders preceed pebble mills in the comminution process.
