  • Chip plate in the rotor of a centrifugal crusher
    Patent number: 5135177
    Abstract: This invention relates to a chip plate provided at the outlet on the circumference of the rotor of a centrifugal crusher. The cemented carbide chip embedded in the chip plate is the either rounded or sloped in the internal part of its tip and, even if the cemented carbide chip is exposed as a result of wear and a mass of rock hits against it, the impact of collision is softened because the said mass of rock rushes out by slipping on it, thus preventing breaking of the cemented carbide chip.
