The Complexity Of Structural Design And Machining Of Twin Screw Barrel Extruder
Twin Screw Barrel extruder structural design and processing of the complexity of the theoretical development is not perfect, but with the Twin Screw Barrel extruder modular design, a variety of geometric shape of the threaded components and barrel components are arranged in combination, according to Experience - theory - practice - inspection, which can be optimized for different mixing requirements, to optimize the design to meet the needs of different process formulations, so that the same twin screw extruder has a strong adaptability. Mainly in the following areas:
1) Mixing performance: Since the two screws are engaged with each other and various thread elements such as a back-threaded element, a meshing disc element, a toothed disc element, Twin Screw Barrel and the like can be added as necessary to precisely adjust the shearing / mixing So that the mixing strength and the mixing quality (whether distributed or mixed) can be effectively controlled. This is a single screw extruder can not match.
2) Processing flexibility: The same Twin Screw Barrel extruder is usually used to measure the amount of starvation feeding, the yield depends on the amount of feeding, independent of the screw speed, is an independent control of the variable, which can be flexible in a machine to deal with more Processing functions such as melting, mixing, venting, reaction and so on.
3) controllability of process parameters: the same time to the Twin Screw Barrel extruder residence time distribution is narrow, better convection heat transfer and precise control of the temperature curve, in the extrusion can get a better shear - time - temperature course , In a wider range of input mechanical energy, which can get better product quality stability.
4) The efficiency of the production process: Twin Screw Barrel the positive displacement of the screw can be used to deal with more diverse raw materials and mixed formula, and the downtime is short.
5) Higher economy: Due to the high process flexibility and productivity, a wider range of end products can be produced and a highly consistent product quality can be provided, Twin Screw Barrel and screw wear can be compensated for by screw speed adjustment.
