| Abstract Scope |
Effect of hematite concentrate on pellet quality was studied. High pressure roller mill was applied to intensify pellet quality. The results shown that compressive strength of preheated pellet and roasted pellet decreased significantly when the hematite proportion was 20%. High pressure roller mill can obviously improve the pellet strength, specially preheated pellet. For 40% hematite, the specific surface area of the raw material was increased to 1883.8 cm2/g after high pressure roller mill. And the drop strength, compressive strength and busting temperature of the green pellet were 7.0 times/0.5m, 16.87 N/P and greater than 550 °C, respectively. The compressive strengths of preheated pellet and roasted pellet were 507 N/P and 3170 N/P, respectively. |
