Abstract: The present invention provides a process for reforming sponge titanium powder into intermediate titanium particles of desirable fluidity and superior bulk specific gravity suitable as a starting material of a titanium or titanium alloy product to be produced by powder metallurgy, comprising the steps of: charging a sponge titanium powder in mill pots of a planetary ball mill together with crushing medium; collapsing the particles of the powder to be consolidated forming a squamation under an inert atmosphere in the mill pots; and adjusting the particle size and particle diameter by cutting the squamated particle under an inert atmosphere in a crushing medium stirring mill.

Abstract: A rotor shearing type crusher for crushing municipal waste and industrial waste whether it is bulky or not. If any foreign material, which is impossible to crush, is mixed with the municipal waste or industrial waste, the foreign material is promptly discriminated and discharged separately. The crusher includes a casing, a feed plate and a cutter respectively rotatably mounted to the casing obliquely above two rotatable knives. The inclination of the feed plate and cutter can be changed freely. Cutouts rae provided on the top end of the feed plate and cutter in a comb-like manner to dodge cutting edges of the rotatable knives intersecting each other. A discharge port is divided into two sections. The crusher of such a construction performs a function of tearing off soft waste twining itself around the rotatable knives. Rigid material impossible to be crushed is separately discharged. Even dangerous small waste such as cartridges, cylinders, etc. can be crushed and degassed inside without fail.

Abstract: An improved cone crusher wherein raw material is crushed between a gyrating mantle and a bowl liner above the mantle. Space between the mantle and the bowl liner is adjusted by moving the bowl liner upward, and the adjusting movement is automatically performed by hydraulic pressure applied evenly to the entire circumference, successfully meeting fluctuation of load and abnormal overload.

Abstract: A novel supporting structure for the crushing head of a cone crusher in which an eccentric rotating in a frame and the crushing head gyrating in the inner periphery of the eccentric are movable up and down by hydraulic pressure, characterized in that a cylindrical socket is inserted in a sleeve of the frame which is slidable up and down while the eccentric and the crushing head are supported by a hydraulic mechanism mounted on the upper end of the sleeve, thereby reducing the overall height of the cone crusher.

Abstract: A novel bearing construction for use in a cone crusher and the like in which an eccentric rotating in a frame and a crushing head gyrating in the inner periphery of the eccentric are movable up and down by hydraulic pressure. A cylindrical socket inserted in a sleeve of the frame is slidable up and down while the crushing head is supported by the upper part of the socket and the eccentric is supported by the lower part of the socket so that the bearing are prevented from wear and trouble during operation.
