Grinding of cement raw material – material separation in cyclones. The cement raw material mixtures are ground, dried, and classified in the Pfeiffer vertical roller mill. For drying the material, hot gases are directed into the mill. Product fineness can be adjusted within a wide range (0.063 to 0.2 mm).
Roll forming is a process in which a strip or sheet of metal, such as steel, is passed through a continual set of stands (rolls) until the desired cross-section profile is achieved. The sheet or strip is plastically deformed along a linear axis in a room temperature environment. Typically used to create parts featuring long lengths, roll forming is also useful for …

In this type of mill, one or both the rollers are adjustable. In its operation, the metal is passed between the two rollers rotating at the same speed but in opposite direction. After each pass, the direction is reversed. The metal piece is turned through 90°, which keeps the section uniform and with fine grains.
