Batch-wise or continuous Processing?
Mixing and compounding are among the most widespread technological processes. Whenever planning equipment for a mixing process, the first decision for the user to take is which processing principle should apply: Batch-wise or continuous processing.
Traditionally, the starting point is batch processing. But especially mixing tasks are often designed as continuous processes. Ingtec Technik offers solutions for both categories, also for special applications like energetic materials.
Some basic criteria, which may help to decide which technology is suited best for a given task:

Raw Material Supply + Simple - Complex
Large Scale Production - More difficult with scale ++ Excellent
Slow Processes + Suitable - Difficult (short residence time)
Set-up Time - For each batch + Only once per run
Processed Volume - = Batch Size + Small
Application of Energy - Low + High
Investment + Low - High
Manpower - High + Low
Process Automation + Low Level feasible - High Level mandatory
Start-Up/Shut-Down Procedure + Short - Complex
Maintenance + Relatively simple - Complex
Process Safety - More difficult with scale + Excellent

Complex mixing and compounding equipment requires sophisticated control systems:
• Managing of Process Procedures: Weighing, Dosage, Mixing, Thermostatting, Vacuum, Manual Process Steps, etc.
• Optimising of Plant and Equipment Utilisation – Administration of multiple batches in a production line -> Campaign Management
• User Interface: Process Visualisation, Setting of Parameters, Formula Administration
• Consistent Data Recording of all Process Parameters
• Statistical Analysis
• Production Planning and Monitoring
• Interface to superior control systems

When processing energetic materials, there is also demand for continuous equipment. Ingtec Technik provides two major technologies for continuous processing of energetics: • Atextruder and • Twin Screw Extrusion
The outstanding advantage of continuous processing is the comparatively low amount of material inside the equipment at a particular time, dramatically reducing the risk potential. The residence time of the product on the machine is very short.
Energetic Materials
When processing energetic materials, the mechanical sensivity of the material against impact and friction is a critical factor in process design.
Typically, compounding of PBX materials is performed batch-wise on vertical kneading machines of the PKV type.
Advantages of the PKV: • Small but well defined distances of the mixing blades, hard contact of mixing tools or vessel is impossible • Product does not get in contact with shaft sealings of the kneader • No dead zones – The entire useful volume is worked by the mixing blades • Amount of shear is well controlled by the torque, applied • Vacuum degassing • Ingtec Technik exclusively uses hydraulic drives in environments, where explosive atmospheres may occur.
Nevertheless, with increasing batch size, perspective may change: • The increasing potential risk of large batches needs to be taken into consideration • Heat exchange is getting slower with increasing kneading vessel size

Atextruder ATE
• Very low hazard potential, owing to the open construction (no confinement) and Small amounts of energetic material present on the
device during processing • Continuous operation, suitable for remote control • Flexible process design, not limited by the rigid position of
ports, arranged on a fixed barrel • Homogenisation of the processed material by shear in the
gap of the roller, the rollers never touching • Variable but very precise adjustment of the distance of
the rollers (roller gap), gradients possible • Shear applied to product by rollers, gap small but well
defined, hard contact of rollers is impossible • Reproducible, constant product quality
The Atextruder has many special advantages:

Twin Screw Extruder
In some applications not only the continuous compounding is required, but also a subsequent forming of the product is desired. In this case, conventional extrusion is the method of choice, because it can provide the necessary pressure on the product for forming. Ingtec Technik offers also Twin Screw Extrusion Technology, especially adapted to the requirements of energetic materials. • Co-rotating screws to limit shear and friction on the products • Folding half barrel design to enable emergency pressure relief • The extruder is operated below the maximum technically feasible feed rate of starting materials to reduce the degree of
filling and hence mechanical stress on the product. Pressure is only generated towards the output zone of the extruder. • If no pressure for forming is required in the process (only compounding), we can offer bearings of the screws on both ends.
In this case the product is exposed only to very gentle pressure during processing.
