1 structure characteristics
Split direction parallel twin-screw extruder is: are the distinctive features of barrel can be split At the same time, the screw and barrel lining can combine casual sex.
2 advantages
1, wear
Because open is convenient, so can find screw elements, barrel inner bushing wear degree, thereby effectively repair or replacement. Not discovered during extrusion products appear problem, cause unnecessary waste.
2, reduce the production cost
Manufacturing masterbatch, often need to change the color, if it is necessary to replace the product, in a few minutes time to open open processing area, also can by observing the melt on the screw profile to analyze the mixing process. Now common twin-screw extruder in changing color, need to use a lot of cleaning machine material cleaning machine, is both time consuming and inefficient, and waste of raw materials. And split casing double screw extrusion machine can solve the problem, change the color, as long as a few minutes can quickly open the machine, manual cleaning, so that it can not use less or cleaning materials, save the cost.
3, improve labor efficiency
In equipment maintenance, common twin screw extruder is often the first to remove the heating, cooling system, then take out the screw as a whole. And split casing double screw is not, as long as loosen several bolts and lift the upper rotation of worm gear box handle device extension tube then open the barrel, and then for repair. Shorten the maintenance time already so, also reduces the labor intensity.
4, high torque and high rotational speed
At present, the world is the development trend of twin screw extruder to high torque and high rotational speed, low energy consumption, high speed effects is high productivity. Split twin-screw extruder which belong to this category, its speed can reach 500-600 revolutions per minute. So in terms of processing and high viscosity, heat-sensitive materials has a unique advantage.
