Vertical roller mills: The new leader in grinding
2019-10-11 Sulphide copper-gold ores are usually sorted by flotation. The standard comminution process to grind the ore to flotation fineness, mostly consists of coarse crushing followed by SAG milling or wet ball mill circuits, or alternatively multiple stage crushing followed by rod and ball milling.
Grinding process within vertical roller mills:
2009-1-1 The data indicate that the product size from the vertical roller mill in the cement plant is far smaller than that of the power plant. The grindability result is the grams of fine particles, which pass a 0.125 mm screen aperture size, produced per revolution of the mill. A standard procedure is used to determine this value.
