In addition to the benefits of height gains and dismantling ease, the innovative design allows dust extraction to be provided by a continuous circular channel on the spiral's outside circumference with a compressed air in-feed from the center channel.
This circular channel was attached to a control gate and a discharge tank through another direct channel which was 5.
The working volume of the loading unit was simplified assuming it as a parallelepiped with a cross-section corresponding the size of moving plate in hydraulic loading unit (55x60 mm), and consisting of two 100 mm length chambers, separated by the diaphragm having a changeable diameter circular channel (from 3 to 12 mm).
Figure 8 shows a cross-section cut of polystyrene taken near the end of the circular channel.
To avoid discretization of the circular channel along the circumference, which would require a lot of small triangular shell elements, and thus save a substantial amount of computer memory, the so-called line source (sink) approach first developed by Barone and Caulk [24] and further extended by Rezayat and Burton [25] for cooling channel simplification in three-dimensional parts was implemented.
Five different die channel geometries were used in this study; a square channel, a rectangular channel, a teardrop shaped channel, a circular channel, and a rectangular manifold channel.
Since the circular channel is radially symmetric, very little layer rearrangement was expected to occur.
Extrudate swell from the square channel approaches its limit much more rapidly with increasing surface tension than does that from the circular channel.
This range includes: trenchless renovation of circular channels with a diameter of dn 300 - 600 mm and channels eggshaped with dimensions 200/300 - 400/600 mm with a total approximate length l = 1641.
