<p><P>PROBLEM TO BE SOLVED: To provide a crusher capable of preventing blocking between a wall surface and rotary blades, reducing time and labor of work for replacing a disk and crushing at a suitable speed in accordance with the kind of crushed materials. <P>SOLUTION: A crusher includes a casing, rotation axis, a plurality of rotary blades and opposite blades; the casing is approximately box-shaped and the rotation axis is attached at the opposite wall surface; the rotary blades are attached in parallel with the rotation axis and have cutting blades on the outer periphery; the opposite blades are attached at the casing via a gap with tip ends of the cutting blades of rotary blades. A cover for covering the wall surface side parts of rotary blades which is nearest to the wall surface is attached on the wall surface; a crusher disk is attached so as to hold the rotary blades on the rotary axis; the disk is engaged at a circular hole which is formed on the both wall surfaces; an annular sliding contact part is attached on the outer periphery and the sliding contact part slides with the wall surface, and each rotary blade is able to change the arrangement pattern of the cutting blades by changing the sequence order of the rotary blades. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
