Iron ore ultra fines crushing

Posted in: , on 28. Jan. 2008 - 09:20

We are in need of a grinding solution for the following application:

Feed: Iron Ore

Bulk Density: 2.5-2.9 t/cum

Moh’s scale hardness: 5 to 6

Tumbler Index: 83-86%

Abrasion Index: 6.5-7

Bond Index: 5% max

Compressive Strength: 3600 kgs/sq cm

Feed size: 0-5mm

Moisture: 15-20%

Output size: 80% passing 0.075 (200 mesh)

Feed Capacity: 40-50tph

Can someone help identify a suitable equipment/tech for this?

We are actually looking beyond Ball mills or SAG/ROD mills. They are power intensive and needs large installations

We have studied the Straight Centrifugal Grinder mill from China, but it can only accept feeds with 8% moisture (max) and the maximum capacity available is 10tph
