Multi-rotary disc type molten slag centrifugal granulating system

The invention discloses a multi-rotary disc type molten slag centrifugal granulating system. The multi-rotary disc type molten slag centrifugal granulating system comprises a slag particle trapping unit (101), a multi-shaft rotary disc unit (102) and a power and power transmission unit (103), wherein the multi-shaft rotary disc unit (102) consists of a center rotary disc, a plurality of non-coaxial auxiliary rotary discs and the like. The multi-rotary disc type molten slag centrifugal granulating system is characterized in that the molten slag is granulated by the multi-shaft rotary discs, sothat compared with the single-shaft system, the treatment amount is larger, the space is saved, and more advantages are realized. The invention also provides a novel rotary disc structure for the granulating of the molten slag; flow guide convex blocks are arranged at the surface of each rotary disc in a center rotary symmetric way, so that compared with the common rotary disc, the size of the granulated molten slag is mo
