Open the CIPO recordAbstract From the Canadian patent
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. - 8 -

Why it's free to use
- Filed January 3, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 3, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 3, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
