Cements ground in the vertical roller mill fulfil the quality
C. Obry. Karl-Heinrich Zysk. Vertical roller mills are the mills traditionally used for processing granulated blastfurnace slag and for grinding composite cements. From the energy aspect they areThe vertical mill system has defects such as a large mill pressure difference and a high system negative pressure. Although the mill output is high, its system power consumption is as high as 17.05 kWh/t. The new wedge-shaped cover nozzle ring is added to the vertical mill.

Fig 4 Sketch of a vertical ring rolling mill. Since the rolling pass is open, vertical machines produce end-face defects (called fish tail) during rolling. Periodically, rolling is to be stopped and the ring flattened on a press or hammer before rolling can continue. There is also an OD limitation on vertical machines in that, in order forVertical hot ring rolling (VHRR) process has the characteristics of nonlinearity, time-variation and being susceptible to disturbance. Furthermore, the ring’s growth is quite fast within a short time, and the rolled ring’s position is asymmetrical.
