Abstract: A vertical roller mill has grinding rollers which roll over a grinding path of a rotatable grinding table, and a surrounding nozzle ring separation area for conveying and separating gas. A coarse fraction of ground material is entrained in gas upwards in ducts from a location that is below, at, or above the nozzle ring separation area and is transported into an entry to a material separator located above the grinding table.

Abstract: A door and hinge mechanism particularly adapted for use in a conical hopper where the door may be on the down side of the hopper. The hinge pin connecting the fixed hinge element with the movable hinge element is placed under tension by springs such as Belville washers so that the hinge pin is not freely rotatably in the fixed hinged element. The movable hinge element includes a cam member which rotates about an off-set axis until the cam surface engages the hinge pin to prohibit further free rotation of the movable hinge. A force must then be applied to the door supplementing gravity to rotate the movable hinge element and hinge pin relative to the fixed hinge element to thereby open the door.
