SOLID CROSS - SECTIONS

Solid Cross -

1. A Typical Die Design for extruding a solid rod is show in figure.
2. In the figure, DD is the diameter of die orifice,  DB is the diameter of bore of extruder barrel, α is the lead -in angle,  and  P is the die land.
3. Because of the screen pack and breaker plate assembly,   the pressure in the extruder (PE)  is reduced by the pressure loss across the assembly (PL).
4. Since the die outlet is at atmospheric pressure,  the working pressure is the die pressure (PD)   given by the difference :
PD = PE -- PL

Breaker Plate & Screen Pack :

Breaker Plate - 1. This is performed metal disk,  with a multitude of small diameter holes. 2. The breaker plate is placed in between the screw and the die assembly. 3. It's principal function is to provide support for the screen pack . 4. The breaker plate helps also to convert the spiral flow of the polymer melts leaving the screw into a linear, axial one. Screen Pack - 1. Screen Pack is usually a multilayered,  nearly symmetrical sandwich of metallic wire screens.  2. It is placed between the screw and the breaker plate,  using the latter for physical support. It's  role is to eliminate the particulate contaminants.  3. The screen pack composition is always based on trade-offs, there is need to eliminate particulates using screens with high mesh,  but at the same time this create flow restriction,  it reduced the throughput, thus low mesh would be preferred.  4. Decision should be made as for as the maximum tolerabl...

Barrel & Hopper Cooling System (Elements) :

                    : Barrel Cooling : 1. Barrel cooling is needed to prevent overheating that may cause degradation. 2. For small extruders fans that blow air over or around the barrel are used. 3. Other cooling system used include . 4. Cooling channel inside the barrel wall. 5. Find on the barrel or on the heaters to speedup that transfer. 6. A watet-fog spray over barrel. 7. Continuous, controlled vaporization of liquid (water) 8. Copper tubing carrying cold water is sometimes used.               *Hopper Cooling Systems* • Water-cooling is used to cool the hopper throat to prevent bridging and to protect the rubber parts present in the screw support  assembly.
