Feed Material
As stone in the feed material was a mixture of Limestone and Shale, operators said that this stone was hard and difficult to crush from previous experience.  Also as it was being dug from the ground, the feed material was dirty and contained a lot of fines material.

As stated above the product from the cone was taken to a wash plant where the customer was producing 6 final products in total:

  • 505 product (20-40mm stone)
