Embodiment 1
[0047] to combine Figure 1~4 As shown in and 6, in the slag granulation method with particle size classification in this embodiment, the blast furnace slag on the rotating slag pan 210 moves to the edge position of the rotating slag pan 210 during the rotation, and the heating member 211 of the rotating slag pan 210 is The blast furnace slag is heated and kept warm; the blast furnace slag is separated from the rotating slag pan 210, and the cooling mechanism 220 cools the blast furnace slag, and the cooled blast furnace slag forms granulated slag; the granulated slag moves to the bottom of the shell 500 under the action of gravity, and is The discharge port 520 at the bottom of the casing 500 falls into the screening unit 400, and the screening unit 400 screens the granulated slag to obtain granulated slag classified by particle size. The specific steps are:
[0048] Step 1: The blast furnace slag stored in the slag pot 110 flows into the rotating slag pan 210 through the sl...
Embodiment 2
[0059] The basic content of this embodiment is the same as that of Embodiment 1, the difference is that: the slag nozzle 221 is arranged above the edge of the rotating slag pan 210. In this embodiment, there are 16 slag nozzles 221, and the slag nozzle 221 rotates along the The circumference above the edge of the slag pan 210 is uniformly distributed. In this embodiment, the slag nozzle 221 uses gas as a carrier to spray fine-grained slag to the edge of the rotating slag pan 210. The carrier for spraying granulated slag can also be other fluids such as water. The smaller granulated slag makes the granulated slag with a certain kinetic energy collide with the blast furnace slag at the edge of the rotating slag pan 210 to grow up. Secondary production and utilization of the granulated slag under resource utilization conditions; on the other hand, the slag film is broken through the impact of the smaller granulated slag and the air-based carrier, preventing the formed slag liquid...
Embodiment 3
[0063] to combine Figure 5 As shown, the basic content of this embodiment is the same as that of Embodiment 1, the difference is that: a raised surface 216 is provided between two adjacent slag troughs 212, and stoppers are provided at both ends of the circumferential edge of the raised surface 216. plate 217, so that the baffle plate 217 is located on both sides of the slag outlet of the slag flow tank 212, and the slag outlet of the slag flow tank 212 is the circumferential side 215. Its function is: the blast furnace slag located on the rotating slag pan 210 moves towards the edge of the rotating slag pan 210 under the action of centrifugal force, and part of the blast furnace slag flows out along the slag flow groove 212 through the slag outlet; On the convex surface 216, and then flow to the peripheral edge of the convex surface 216, when this part of the blast furnace slag moves to the peripheral edge position of the convex surface 216, it will be blocked by the baffle ...
