    • The roller mill according to the invention consists substantially of two grinding rollers which are driven in opposite directions and form between them a grinding gap for comminuting material to be ground, and a delivery chute via which the material to be ground is fed to the grinding gap. Furthermore, there is provided in the delivery chute a pressure sensor for measuring the static gas pressure, which pressure sensor is connected to a control or regulating device, which changes the circumferential speed of the grinding rollers in dependence on the measured static gas pressure. In the method according to the invention for operating the above roller mill, the static gas pressure in the delivery chute is measured and used to control or regulate the circumferential speed of the grinding rollers.
    • 根据本发明的辊磨机基本上由两个研磨辊组成,它们沿相反方向驱动,并在它们之间形成用于粉碎待研磨材料的研磨间隙,以及待研磨材料通过其被供给到研磨间隙的输送槽 。 此外,在输送槽中设置有用于测量静态气体压力的压力传感器,该压力传感器连接到控制或调节装置,其根据测量的静态气体压力改变研磨辊的圆周速度。 在根据本发明的用于操作上述辊磨机的方法中,测量输送槽中的静态气体压力并用于控制或调节磨辊的圆周速度。
