Abstract

PURPOSE: To prevent occurrence of a closed state due to adherence of clay or the like to surfaces of a chute, by arranging an outer cylinder in the periphery of the vertical chute of a coal crusher and flowing cool air in its annular space simultaneously setting wall surface temperature of the chute to a specific value.
CONSTITUTION: An outer cylinder 17 is arranged in the outside of a chute 8 to form an annular space 20 in its area from a casting part to crushing part of coal. Cooling air A1 is supplied to this space 20 from a feed pipe 18. It is preferable to hold wall surface temperature of the chute to not higher than 100°C at which coal with high content of clay decreases its security power. In this way, the chute is cooled, then solidified clay contained in coal is prevented from adhering to an inner wall of the chute at high temperature, simultaneously cooled air is jetted from a lower outlet to improve a classifying effect of a classifier.
