The operating process of this system is briefly explained.

Start up the system and let the system control means control the role of all the components.

When the raw material is introduced into the hopper 11, the extruder 12 is operated to bring the raw material into a molten state and pressurized to be discharged to the extruder outlet 15.

The melt flowing to the outlet 15 fills all of the 360 degree inlet space 67 between the case and the drum body, and when the pressure increases, the melt passes through the first through hole 63 of the first body and then the circular groove 65. After gathering, it passes through the relatively large second through-hole 68 of the second body and is collected in the center of the drum body to flow out to the outlet 66. If the device is two-stage, the melt coming out of the first stage outlet is introduced into the inlet of the next stage, pressurized and warmed by a screwdriver, and then passes through smaller through holes in the same path to separate fine particles and discharged to the outlet. In this case, while passing through the nozzle hole 17 of the nozzle unit 16, it is discharged into a thin rhythm, cooled and cut into a pellet.

In this process, the system control means controls the drum body driving means to rotate the drum body when the fluid supply pressure of the 360-degree inlet space of the drum body exceeds a predetermined value, that is, if the through holes of the drum body are blocked by foreign matter. When the drum body is rotated in the clockwise direction, the bulky ones of the foreign materials blocking the through holes are caught by the second blade 43 and gathered into a temporary space (44-1 incision) for discharging the foreign materials. Small foreign matters that pass through are separated from the through hole and the surface of the drum body by the first blade and are collected in a temporary space (42-1 incision) for discharge. Turning the drum body once or several times removes foreign matter from the surface of the drum body, so that the melt easily passes through the drum body and thus the pressure is reduced, thus stopping the drum body driving means. By operating the discharge means to discharge the foreign matter temporarily stored in the temporary space.

The foreign substance discharge means operates the cylinder 47 to retract the cylinder rod 48 to the frame to which the first and second diaphragms 42 and 44 are attached, respectively, to discharge the V-shaped discharge plate of the scratch discharge plate. Foreign substances scratched in the temporary space at the end of the passage are discharged to the outside of the case through the scratch outlet by pressure. At this time, by maintaining the temperature of the foreign matter discharge means 10 ~ 20 degrees Celsius higher than the flow material to control the discharge to be smooth.
