ing rollers can be swung hydraulically out of the mill housing; the two roller units remaining in the mill then continue the grinding process. The new mill system from Krupp Polysius thus fulfils the prerequisites for »online operation« in the cement factory with a practically uninterrupted flow of material from the mill to the kiln.
Mill Machining, Milling Process, Horizontal & Vertical Milling Machines Definition. Milling is a process performed with a machine in which the cutters rotate to remove the material from the work piece present in the direction of the angle with the tool axis. With the help of the milling machines one can perform many operations and functions starting from small objects to large ones.
