CRUSHER

PROBLEM TO BE SOLVED: To provide a crusher which adjusts the size of a crushed object capable of passing through an upper lattice member with a simple structure.SOLUTION: A crusher 1 includes: a rotor 2 rotatably provided in a crushing chamber 6 and having a hammer 3 at its outer peripheral part; an upper discharge port 4 formed above the crushing chamber 6 to discharge crushed objects crushed by the hammer 3; and an upper lattice member 11 provided at the upper discharge port 4 and having lattice holes 15 for passing the crushed objects of a size which is equivalent to or smaller than a predetermined size. The upper lattice member 11 includes: a first lattice 12 having a plurality of first through holes; and a second lattice 13 provided adjacent to the first lattice 12 and having a plurality of second through holes. The first through hole and the second through hole communicate with each other to form the lattice hole 15.SELECTED DRAWING: Figure 1 【課題】簡易な構成により、上部格子部材を通過できる被破砕物の大きさを調整できる破砕機を提供すること。【解決手段】この破砕機１は、破砕室６内に回転可能に設けられ、外周部にハンマ３を有するロータ２と、破砕室６の上部に形成され、ハンマ３により破砕された被破砕物を排出するための上部排出口４と、上部排出口４に設けられ、所定の大きさ以下の被破砕物を通過させるための格子穴１５を有する上部格子部材１１と、を備える。上部格子部材１１が、複数の第一の貫通穴を有する第一の格子１２と、第一の格子１２に隣接して設けられ、複数の第二の貫通穴を有する第二の格子１３と、を有する。格子穴１５が、第一の貫通穴と第二の貫通穴とを連通させることで形成される。【選択図】図１
