Structure composition:

The machine group is made up of feeding device, power driving mechanism, mixing and extruding device, base, heating / cooling temperature control system, vacuum system, electric control system as well as down stream equipments.

Basic structure and characteristics:

1. Mixing and extruding devices
a， The mixing and extruding device is the core of this machine which is made up of the barrel and its bush， driving core shaft which is provided with the feeding section， screw of extruding section， millstones of mixing and plasticizing section and machine head.
b， The screw of feeding section is a single screw with large diameter and deep screw channel， it is applicable to material handling / extruding of high-torque and big power of high-pressure with high productivity.
c， The six pairs of auxiliary millstones of the mixing plasticizing section and their moving disk is in series disposed on the core shaft and the fixing disk is fixed on the barrel. On the working surfaces of moving disk and fixing disk are uniform distributed with grooves of different shapes and sizes. The moving disk is driven by core shaft and is synchronous rotated with the screws of feeding section and extruding section. The filling materials are conveyed by the screw of the feeding section and through the clearance of the working surface of six pairs of fixing disk and moving disk to be forced crush grinding， shearing， scattering， mixing and plasticizing with superior and good quality mixing.
d， The extruding screw is single screw with small screw distance and shallow groove， its diameter is less than the diameter of the screw for the feeding section. The flange at the end of the barrel is connected with the flange of the machine head by gemel structure and it is removed and installed quickly and conveniently.
     e， The materials of screw， millstones， barrel bush and machine head are made by alloy materials of high temperature and wear resistant that is applied to materials processing of rigid and high wear resistant.
f， The clearance of the millstones can be adjusted by adjusting nut， it is adapted to the requirements of different kinds of material formulations and process conditions.
     g， The configuration and the numbers of millstones surface， configuration and length- diameter ratio of the screw for extruding section can be particular designed according to physical and technical requirements  from the customers.
2. Feeding device
It adopts automatic metering method to control weight according to the characteristics of different materials formulations; feeding mode can be selected deadweight falling mode or forced feeding mode or to choose two ways for feeding different materials at the same time.
3. Heating / cooling temperature control system
Along the length of outside round of the barrel are provided with six parts of cast copper electric heater to heat the barrel， the conventional design for maximum temperature is 300 ° C (if any special requirements， it can be designed for 400 ° C)， customers can regulate the barrel temperature according to technology conditions; the barrel is provided with thermal resistance sensor， the machine head is installed with  high temperature melt pressure sensor， all above have adopted digital LCD control instruments to regulate temperature and pressure in order to meet the processing requirements of materials with viscous flow and high temperature.
The barrel and its connecting fixed millstones is a jacket hollow structure which can cool the barrel by forced circulating the guiding hot oil in order to balance temperature of the work region.
4. The exhaust and vacuum system
The central part of the barrel in the extruding section is provided with a barrier or a discharge hole which is connected with the pipe of the vacuum system for exhaust.
5. Power driving system
The power of the machine group is adopted with AC variable frequency motor， if customer needs， he can also choose DC speed control motor; the main driving is adopted with special decelerator for the screw extruder and itself is equipped with forced lubrication system.
6. Electrical control system
The machine group takes programmable controller (PLC) as the main control unit of the whole machine and auxiliary with touch screen control and AC frequency conversion control for central controlling the various parts of the machine and coordinating continuous mixing process of the whole machine. At the same time， it uses button operation and signal indicator light to monitor the safety operation and fault condition of the group.
7. Down stream equipment
The down stream equipment is special designed for the shape of the final products， properties of materials used and their processing requirements.
