gneuß Knoss screw extruder

gnousKnoss screw extruderGenerally, it is a single screw extruder with a special degassing section. The polymer melt is fed into a large single screw drum. The drum contains 8 or 10 (depending on the model size) small extruder barrels, parallel to the main screw shaft. In the small barrel is the "satellite" screw, which is driven by the ring gear in the main barrel. When the "satellite" screw rotates around the screw axis, it is in the opposite direction to the main screw. This asymmetric operation design can increase the surface exchange of polymer melt. Meanwhile, avoid the meshing issues in traditional multi axis or multi screw designs.

Due to its surface area exchange rate, the MRS extruder can provide excellent transfer in most cases, with a vacuum of only 30 mbar. This allows for the use of simpler and more robust water ring pumps, reducing daily maintenance at least. Under normal circumstances, the MRS extruder operates with a 25mbar low maintenance liquid ring vacuum system in standard applications, through enhanced surface area exchange combined with deeper vacuum (such as 0.5-2mbar).

In traditional PET processing technology, the PET drying process is complex, with high maintenance costs, high investment costs, large factory area, and high operating costs. However, the use of MRS extruders can directly process PET particles without the need for pre drying. The factory's footprint can be reduced by 25%, and energy efficiency requirements can be reduced by 25%.

The energy consumption of MRS technology is 15% -25% lower than traditional technology, and it does not require a dryer or high vacuum system, reducing maintenance.

Because there is no need to pre dry PET,gnousKnoss screw extruderIt can quickly convert from PET to PP, and vice versa. This customer can produce a large number of different products on the same production line and achieve short conversion time. Greatly improve production efficiency.
