If you have substances such as smelting and other slag and the like., By grinding into a. if possible If you want to bring it into a finely divided form, it is advantageous to granulate it beforehand, because the immediate Milling the cooled materials is relatively expensive.

The invention now has a granulating device as an object in which the liquid slag in a known way on a rotating centrifugal body, expediently in the form of an inverted bell, abandoned wind, which throws sk as a veil and brings it into the area of a water shower, and consists in that the centrifugal body is equipped with a self-centering device.

The self-centering device exists according to the invention from a resilient mounting of the centrifugal body with non-linear reaction, which causes the sling body to be considerably overweight or eccentric, as they can occur in operation, can record without affecting the housing of the Granulating device vibrations are transmitted.

The invention will be described in detail with reference to the drawing, which shows an

G 10122 IVc / 80b exemplary embodiment for the granulating device illustrated. It shows Fig. Ι a vertical section through the device for granulating liquid Hütten- .5 and other swallowing and other similar substances, Fig. 2 is a plan, partially in section, along the line II-II in Fig. I. In the case of the granulating device shown, the centrifugal body 2a, onto which the molten material to be granulated falls from a channel 2, has the shape of a bowl or an inverted bell and rotates at high speed around a vertical axis 3 ,,. The bowl, to the shape of which the slingshot is not bound, is on theirs. Inner surface preferably lined with a protective layer of refractory cement or brickwork. It is set in rotation by a motor 4 via the shaft 3ß, a speed-multiplying gear 17 driven by V-belt 5, a shaft 18, two bevel gears 19 and 20, a shaft 2.1 with a universal joint 22.: 'In in practice is a steady work. 25 of the centrifugal body 2a is of the greatest importance even under changing loads and is essential for the production of perfect granules. This cannot be achieved with an unyielding mounting of the centrifugal body. The invention provides, with its essential features and for the designated purpose, to mount the slinger 2a so that it is extremely flexible around its equilibrium position, so that it can then absorb considerable overweights or eccentric loads without causing any vibrations on the fixed part of the device. ··,. In the illustrated embodiment, a gyro-like self-centering device with non-linear elastic return is provided. This solution has numerous advantages. ■■ both in terms of safety and good running 'of the device. The amplitudes are limited even in the special cases of resonance, without the need to use energy-consuming or damping devices. The movements around the equilibrium position, which are caused by the irregular inflow of the liquid substance onto the bowl, are no longer perceptible outside the suspension or storage and help to improve the distribution of the liquid mass is of particular "importance" for achieving perfect operation of the slingshot body. The center of gravity of the whole thing lies vertically above the hinge point of the system. The slingshot body2a is statically stabilized by an elastic bearing. This self-centering device is formed by six tension members which connect the holder 23 of the bearing 30, in which the shaft 30 rotates, to the rigid housing or the frame 1 "of the device; 'Each of the pull members consists of two rigid rods 24, one of which engages the holder 23 and the other engages the housing 1, and the opposite ends of which are connected by an elastic member made up of cables 25 which wipe ζ. two plates 26 are stretched out. The rods 24, which are closest to the axis of the device, run inside the holder 23. The holder has chambers 31 around the rods which allow water to circulate through the. Protects rods against temperature changes. The self-centering device represents an elastic return which is essentially linear in a normally not exceeded range of weak amplitudes. Outside of this. In the area, the feedback grows rapidly, which means that the whole thing takes on a non-linear character. - - ■ Claim-Ε: - ■ · ■ --.- ■ - ~ -.-. ^. - - 1.
