1 structural characteristics
To split with the remarkable characteristics of parallel twin-screw extruder is: thebarrel can be split at the same time, the screw and barrel inner lining can be freelycombined.
2 advantages
1, wear
Because of easy opening, so can always find the wear degree of screw elements,barrel bushing, thereby effectively repair or replacement. Not found in the problemof extrusion products, resulting in unnecessary waste.
2, reduce the cost of production
Manufacturing masterbatch, often need to change the color, if necessaryreplacement products, open the opening processing area type in a few minutes, it may also be observed through the melt profile throughout the screw carries on theanalysis to the mixing process. At present, double screw extruder in the replacement of ordinary color, need a lot of Qing machine cleaning machine, which is time-consuming, costs of electricity, and the waste of raw materials. The split typedouble screw extruder can solve this problem, change the color, as long as a few minutes cylinder can be opened quickly, artificial cleaning, so that it can be used without or less cleaning materials, saves the cost.
3, improve labor efficiency
In equipment maintenance, twin screw extruder are often common to put theheating and cooling system is removed, and then the whole out screw. And splitdouble screw is not loosened, as long as a few bolts, turn the handle device of gear box lifting the upper half part of barrel can open the entire machine barrel, and then repair. So as to shorten the maintenance time, reduces the labor intensity.
In 4, Gao Niuju, high speed
At present, the development trend of the world of twin screw extruder is developing to high torque, high speed, low energy consumption and high speed direction,bring the effect is high productivity. Split type double screw extruder which belongs to this category, its speed can reach plus 500-600 rpm. It has unique advantages in the processing of high viscosity, heat sensitive material.
