<p>PROBLEM TO BE SOLVED: To provide a crushing system suitable for efficiently crushing a raw material, by using a vertical crusher and a mixing chamber.SOLUTION: There is provided a crushing system 10 including a mixing chamber 50 which mixes first hot gas G1 raised in the temperature by a heating device 70 and second hot gas G2 taken out of an upper takeout port of a vertical crusher and supplies the mixed hot gas to the vertical crusher. In the crushing system 10, a damper is arranged as a wind direction adjusting plate in a hot gas flow passage in the mixing chamber, and a temperature measuring instrument is arranged in each of a plurality of gas supply ports 33A and 33B provided in the vertical crusher. With the above-mentioned constitution, the gas temperature is measured in each of the gas supply ports existing in a plurality of places, and when the temperature is different in the respective gas supply ports, an angle of the damper in the mixing chamber is changed, and a change is imparted to the gas flow direction, so that the temperature of the hot gas supplied to the gas supply port of the vertical crusher is adjusted.</p> |
