Abstract
A melt processing plant is provided that includes a melt charger for charging a processing head, in particular a pelletizing head, with melt, in which a diverter valve for discharging the melt during a starting and/or retooling phase is associated to the melt charger upstream of the processing head. A splitter divides the discharged melt into melt portions with the melt channels of the splitter head having at least one step-like cross-sectional enlargement of their inflow portion, a cross-sectional shape different from the outlet cross-section of the discharge channel, and an open orifice region out of the splitter.
Claims38
A melt processing plant, comprising:
- a melt charger for charging a processing head with melt;
- a diverter valve between the melt charger and the processing head for discharging the melt past the processing head;
- a splitter for splitting the discharged melt strand flowing out of the diverter valve into melt portions, said splitter including a movable splitter head with a plurality of melt channels, each of said plurality of melt channels being brought cyclically into flow connection with a discharge channel coming from the diverter valve by moving the splitter head, the discharge channel having an outlet;
- and
- the melt channels of the splitter head having at least a step-like cross-sectional enlargement in their inflow portion, a cross-sectional shape different from the outlet cross-section of the discharge channel, and an open orifice region out of the splitter, upstream of the step-like cross-sectional enlargement the melt channels having an at least partly rounded cross-sectional shape and downstream of said cross-sectional enlargement the melt channels having a polygonal cross-sectional shape.
A melt processing plant, comprising a melt charger for charging a processing head with melt, a diverter valve being provided between the melt charger and the processing head for discharging the melt past the processing head, and including a splitter for splitting the discharged melt strand flowing out of the diverter valve into melt portions, the splitter including a movable splitter head with a plurality of melt channels that, by moving the splitter head, are each brought cyclically into flow connection with a discharge channel coming from the diverter valve, the plurality of melt channels of the splitter head at least having a step-like cross-sectional enlargement in their inflow portion, a cross-sectional shape different from the outlet cross-section of the discharge channel, and an open orifice region out of the splitter, each of the plurality of melt channels having an open circumferential portion without walls on its circumference.
