Abstract
A first rotor disk (21) and a second rotor disk (22) having a plurality of crushing pins (30) mounted so as to form rows along the circumference are opposed to each other and rotatably supported within casings (14, 15). The first and second rotor disks (21, 22) are rotated to crush materials to be crushed which are charged into the casings (14, 15). The crushing pins (30) are mounted on the first and second rotor disks (21, 22) in a cantilever manner. Escape spaces are provided on the first and second rotor disks (21, 22) so as to face to the extreme ends of the crushing pins (30).
Claims12
A crushing pin type crusher comprising a casing, a first rotor disk (21), a second rotor disk (22), a plurality of crushing pins (30) mounted on the first and second rotor disks (21, 22) so as to form a plurality of rows within the casings (14, 15), wherein at least one of the first and second rotor disks (21, 22) is rotated to crush materials which are charged into the casings (14, 15), wherein the crushing pins (30) have metal members (44) mounted on the first and second rotor disks (21, 22) in a cantilever manner, and tubular ceramic members (43) detachably mounted on the metal members (44), and a ceramic protecting member (49A) fixed to the second rotor disk (22) wherein an L-shaped clearance (49B) in a cross section is formed along a root end periphery of the tubular ceramic member (43) between the tubular ceramic member (43) and the second rotor disk (22).
A crusher comprising a casing (14, 15), a rotor disk (21, 22), a plurality of crushing pins (30) mounted on the rotor disk within the casing (14, 15), wherein the rotor disk (21, 22) is rotated to crush materials which are charged into the casing (14, 15), wherein each of the crushing pins (30) comprises a metal member (44) mounted on the rotor disk (21, 22) in a cantilever manner and a tubular ceramic member (43) detachably mounted on the metal member (44), the metal member (44) having generally a tapering portion, and a largest diameter (C) of the tapering portion of the metal member (44) is 1.4 to 3.5 times a smallest diameter (B), wherein the outer shape of the ceramic member (43) is generally cylindrical, and the largest diameter (C) of the metal member (44) is 1/4 to 1/2 times an outside diameter (A) of the ceramic member.
A crushing pin type crusher comprising a casing, a first rotor disk (21), a second rotor disk (22), a plurality of crushing pins (30) mounted on the first and second rotor disks (21, 22) so as to form a plurality of rows within the casings (14, 15), wherein at least one of the first and second rotor disks (21, 22) is rotated to crush materials which are charged into the casings (14, 15), wherein the crushing pins (30) have metal members (44) mounted on the first and second rotor disks (21, 22) in a cantilever manner, and tubular ceramic members (43) detachably mounted on the metal members (44), and a protecting member (49A) fixed to the second rotor disk (22) wherein an L-shaped clearance (49B) in a cross section is formed along a root end periphery of the tubular ceramic member (43) between the tubular ceramic member (43) and the second rotor disk (22).
