Abstract (en)

[origin: EP3238824A1] This vertical roller mill is provided with: a rotary table having a grinding surface; a grinding roller (3) for biting and grinding a material between the grinding surface and the same; and a scraper (13) for adjusting a layer thickness of the material supplied to the grinding roller (3). The scraper (13) has: a scraper body (15) separately arranged above the grinding surface of the rotary table; a mobilizing means (16) for allowing the scraper body (15) to move in a direction away from the grinding surface; and a resistance adding means (17) for adding a resistance force to the movement of the scraper body (15) in the direction away from the grinding surface. Even when the layer thickness of the material supplied onto the grinding surface of the rotary table fluctuates, a height position of the scraper is automatically adjusted according to the fluctuation in layer thickness.
