How To Video Index Conveyor Drive Design Maintenance. CEMA gives a frictional coefficient of 0.01 for wood chips. To calculate the drag for this material, use the equation: 0.01 x 15′ x (4″)2 = 0.01 x 15 x 16 = 2.4 lbs. Notice that the frictional coefficient of iron ore is 27.6 times higher than that for wood chips. Therefore, the ..

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...
