INTERNAL HEAT GENERATION PREVENTION MECHANISM FOR UNIAXIAL CRUSHER

摘要

PROBLEM TO BE SOLVED: To provide an internal heat generation prevention mechanism capable of preventing the heat generated at a high temperature due to the crushing action by a crushing edge in a uniaxial crusher by directly giving cooling action to a heat generated part with a simple mechanism at a low cost. SOLUTION: The uniaxial crusher is provided with a rotary cutter 5a arranged on the outer circumference of a rotary rotor 5 and a fixed cutter 6 provided at the end of a bed plate 4. A ventilation hole 5p is provided in the axial center of the rotary rotor 5 and a blow-off hole 5Px communicating with the ventilation hole 5p and provided to cross is provided in the rotor radial direction. Compressed air is charged from an air pipe connected to the end of the ventilation hole 5p and blown off to the heat generated part from the blow-off hole 5Px to cool. COPYRIGHT: (C)2003,JPO
