  • A Comparison of Pellet Quality from Straight .Diese Seite übersetzen

    ABSTRACTBoth straight-grate and grate-kiln furnaces have been accepted in the iron ore industry. Both are considered to be roughly equal when comparing overall costs and expenses versus the final product production rate. However, the product quality of these two systems is not equal. This is shown by critically examining the dust generation of pellets from several facilities.
