Ore Sizer Applications in Mining.

Below are examples from our client base highlighting the benefits of the Ore Sizer VSI crusher for use in mineral extraction (gold, copper-nickel, platinum mining).
The great advantage with the Ore Sizer VSI is in the differential crushing affect that happens within the crusher during normal operation achieving the following significant increases in production and yield for mining companies.

Example 1:

Customer: Gold mine operator in South Africa.  Extraction method: heap leeching.  The introduction of the Ore Sizer VSI increased the yield of the leeching production by 18-20%.  This was due to the crushing action within the Ore Sizer, which meant that the ore body fractured significantly more along the weaker fault plains in the ore, thus exposing more of the gold.  This was consistent throughout the ore sizes.  Please remember this is one customerís results, other customersí yields may vary.

Example 2:

Customer: Gold mine operator in South Africa.  Extraction method: Smelting furnace.
The Ore Sizer VSI was introduced to increase the fines content of the ball mill feed (normal feed was from Nordberg Cone Crusher, this was fed through an Ore Sizer VSI and then on to the ball mill).  The result was an increase of ball mill production of 22%.  This improvement was replicated with their other ball mills.
We have several word of mouth testimonies.  Although we are not allowed to tell new customers officially of the results gained, you can rest assured that there are significant improvements in both yield and production around the figures quoted above.
