PURPOSE:To dispense with the operations of a worker in a reaction vessel by placing a main crusher body in the vessel, and efficiently crushing the caked packing material in the vessel by the high-pressure water injected from a water jet nozzle loaded on the main body. CONSTITUTION:A crusher 10 is used to crush the caked packing materials 2a and 2b in the reaction vessel 1. In this case, the main body 11 is brought into the vessel 1 from a manhole 3, and set at a desired position in the vessel 1. The water jet nozzle 26 for injecting high-pressure water to crush the materials 2a and 2b is provided to the main body 11, and made freely approachable to the materials 2a and 2b in the vessel 1. As a result, the operations of a worker, etc., in the vessel can be dispensed with, and crushing of the materials can be performed by remote control. |
