- the device comprises two oppositely opened squirrel-cage cylinders by a support ring 16, a stringer 31 and a rotating end cap, wherein the stringers and the brackets are bolted together to form a frame.
- a synchronously rotatable splitter disk 9 is disposed between the open sides of the two cylinders.
- the two cylinders are divided into two relatively independent cavities, and the torque of the splitter disc is derived from the mandrel 6.
- the lower part of the splitter disc is a stationary fixed ring 12 which is semi-annular in shape and serves to separate the two cavities while blocking leakage of the slag 7 and the cooling body 8.
- a discharge funnel 13 Directly below the barrel is a discharge funnel 13 for centralized discharge. Eight sets of roller devices are placed at a certain angle in the lower part of the four support rings
- the fixed casing 14 is located outside the rotating cylinder and acts as a seal.
- the steel slag is discharged into the funnel 1 and falls on the diverter disc 9 and is separately diverted into the two cylinders.
- the cooling body steel ball 8
- After cooling and crushing by the cooling body (steel ball) 8 when the particle size reaches a small size, The gap between the rafters leaks out and is discharged through the discharge funnel 13; the steam generated in the process is collected by the fixed casing and discharged through a special hood and chimney.
- the device realizes vertical slag and solves the problem of feeding high viscosity slag more perfectly.
- the drum is a single-layer cylinder structure, the cooling of the slag is insufficient, and red slag is likely to occur.
- There are many support devices and the equipment is heavy; the lower space is limited, and maintenance and overhaul are inconvenient.
- the fixing ring is located at a lower portion of the rotating shunt plate, in the middle of the cylinder, the fixing ring includes a substrate and a side plate, and the side plate is provided with a plurality of concave portions.
