<P>PROBLEM TO BE SOLVED: To efficiently crush a bulky mass included in combustion ash. <P>SOLUTION: A crusher for combustion ash mass includes: a bearing member 1 including a function of receiving combustion ash D generated within a furnace of a combustion apparatus by its upper surface section 2; and a pressing means 10 that approaches or breaks away from the upper surface section 2 of the bearing member 1. The bearing member 1 includes a plurality of holes 5 penetrating between the upper surface section 2 and a lower surface section 3. The pressing means 10 includes a function of pressing the bulky mass E that has not passed through the holes 5 from among the combustion ash D received by the upper surface section 2 of the bearing member 1 toward the holes 5 for crushing to a size for passing through the holes 5. The pressing direction to the bulky mass in crushing is oriented toward an upper surface of the bearing member, so that gravity can be utilized in pressing operation by the pressing means. Thus, power required for pressing the bulky mass can be reduced for efficient crushing. Also, since a discharge restriction is provided by the bearing member 1, a compression effect to the bulky mass can be increased. <P>COPYRIGHT: (C)2012,JPO&INPIT |
