| 摘要 |
The invention relates to a blade bit to be attached to a chuck in an envelope surface of a crusher rotor, the blade bit (1) having four corners and arranged for being attached to the chuck such that an angular-shaped tip of the blade bit points outwardly from the envelope surface, substantially in the radial direction of the rotor, whereby the rear surface of the blade bit, which acts as its attachment surface to the chuck, comprises a support surface (9) preventing the blade bit from rotating, which support surface also enables sliding of the blade bit towards the envelope surface (3), when the blade bit is being attached, until the blade bit is supported to the envelope surface. |
