ABSTRACT:
An improved vertical shaft impact crusher, and in particular a crusher having a shoe assembly attached to a rotatable table assembly, the shoe assembly comprising a bracket, a shoe, and mounting bolts for removably attaching the shoe to the bracket. The shoe has a contact surface which engages a support surface of the bracket to reduce shear forces in the mounting bolts during rotation of the table assembly. The crusher also has a liner for protecting an outside face of the bracket. The liner has spacers located on a mounting surface which create a gap between the liner and the bracket, thereby reducing a prying action caused by uneven deflections in the mounting bracket during rotation of the table assembly.
