摘要：PURPOSE:To eliminate change in the shape of a crushing chamber, deterioration of crushing performance, increase of electric power consumption and increase of mechanical vibration by thickening the wall thickness of the liner for a concave in comparison with the wall thickness of the liner for a mantle and making the outside diameter of the liner for the concave larger than the liner for the mantle and also forming annular gaps whose cross-sections tilted to the central side for the vertical face show a triangular shape to the outermost circumferential parts of both the liner for the concave and the liner for the mantle. CONSTITUTION:The wall thickness of the liner 9 for a concave is thickened in comparison with the same of the liner 8 for a mantle. Moreover the annular gaps T, T whose cross-sections tilted by dimension C to the central side for the vertical face show a nearly triangular shape are provided to the outermost circumferential parts of both the liner 9 for the concave and the liner 8 for the mantle respectively. Further the outside diameter of the liner 9 is made larger than the outside diameter of the liner 8 by 10-40mm. Thereby rebound phenomena of the tip part (external circumferential part) correspondent to abrasion are solved. While tilting close to a new article is continued, the liners are used to the critical point of the minimum wall thickness without waste Therefore the service life of the liners is prolonged to about 1.5-
2 times.
