WIPO Patent Application WO/2014/109025
Kind Code:
A1
Abstract:
A vertical crusher (1) is provided with rotating crush rollers (3). The vertical crusher (1) crushes between a rotating table (2) and the crush rollers (3) a raw material supplied onto the rotating table (2), blows up the crushed raw material by gas introduced from a gas introduction opening (33) provided below the rotating table (2), and extracts the crushed material together with the gas from an upper extraction opening (39) provided above the rotating table (2). An annular passage (30) for blowing gas upward is provided at the outer periphery of the rotating table (2). The gas introduction opening (33) is bifurcated and interconnected with the annular passage (30) and is provided with: an air flow rate control damper (31) which adjusts the amount of supply of gas flowing into the bifurcated passages; and air flow direction control dampers (32) which are respectively provided to the bifurcated passages and which control the direction of gas which flows into the annular passage from the bifurcated passages. When supplying gas to the vertical crusher (1), the flow of gas which is introduced into the crusher can be made uniform by controlling the air flow rate control damper (31) and the air flow direction control dampers (32).
