Crusher for reduction of mined coal size - has rotating crusher with increasing radius acting against baffle plate to reduce coal size for conveyor

摘要

Coal is reduced to a size suitable for its transport by conveyor. A crushing roller with crushing tools on its periphery is mounted on a shaft and supported at both ends. The crusher is mounted with its axis (4) at any angle to the floor at the face corner area, and a bent deflecting baffle (44) is provided at a distance from the crushing roller (20) deflecting the coal flow. Crushing tools (35) project into the deflecting channel produced between the baffle (44) and the crushing roller (20).
