How to choose the cutting method of different modified granulation #granules making machine

In December, at the end of the year, there are still machine delivered to different countries,to clients’ factory. Our engineer is busy installing the compounding machine.

From Iran

Machine name: Mixing machine single screw color master granulation line
Capacity: 500kg/h
Usage: PE Color masterbatch

From Turkey

Machine name: TPE Twin-screw underwater cutting granulation line

Capacity: 400kg/h

Usage: TPE roadblocks, road cones

From Libya

Machine name: PET Twin-screw water cutting granulation line

Capacity: 800kg/h

Usage: PET sheet and packaging material

When the pure resin encounters "modification", the more suitable cutting method usually changes.

Fill in

In particular, high filling usually allows LLDPE or LDPE pelleting to be switched by water ring to an air-cooled die heat. Not only increase stiffness, but also save electricity (save after drying); The grain shape is beautiful and reduces the consumption of edge powder.#pelletizing equipment

Enhance

Because of the presence of glass fiber or carbon fiber, let some air-cooled hot resins (HDPE, ABS, etc.) fall back to the traditional strip (water) cold cut. "Universal", "engineering" (plastic), can not be excluded.

Toughening

For example, TPV bumper exclusive material (PP+EPDM+POE dynamic vulcanization), because the dispersed phase of rubber powder fills in the PP continuous phase, the water ring heat becomes the first choice. Both beautiful and cost saving.

Reactive extrusion

(1)Chemical crosslinked wire and cable (XL-PE) the first choice is air cooled die heat. In many wire and cable factories, twin-screw/single-screw double-stage machine + air-cooled heat (or eccentric heat) is SPVC and XLPE compatible production and processing standard.

(2) In the production and processing of high melt strength polypropylene (HMS-PP), water ring hot grain can be simply carried out after the reaction extrusion of PP.

Cut grain type selection case

1. SPVC cable insulation material or transparent body medical exclusive material, the first choice is all air cooled die surface heat. So is RPVC, but in smaller quantities. #pvc compounding machine

2. Polystyrene, regardless of HIPS or GPPS, the majority of the cast belt (inclined water cooled) cutting line.

3. ABS exclusive material, most of the selected rod (water) cold cut (thin and long grain shape is the most sought after). People have tried air-cooled heat or water ring heat can be, the grain shape is also beautiful and generous (positive spherical). When the output exceeds 3-4t/h, it is natural to change the underwater heat or strip casting machine.

4. Shielded or semi-shielded wire material, small water selection ring, large underwater selection (hot).

5. Silane cross-linked cable material, small line choose water ring, large (such as 96/250 line) choose underwater (hot).

6. HFFR (low smoke halogen-free cable material) production processing and cutting, compatible with XLPE equipment, but the screw configuration to change.

7. Copolymer formaldehyde (POM) sealing end, can choose water ring or underwater (cut).

8, TPU (thermoplastic polyurethane elastomer), multiple selection of underwater heat, but the extrusion metering section of the same direction must be adjusted for pressure construction.

9. PET filament masterbatch, can be cold cut with drawbar (water) or cast strip cold cut.#compounding twin screw extruder

10. Energy saving and emission reduction PPC (polypropylidene carbonate), can be blended with almost every kind of degradation resin (TPS, PLA, PBAT, PBS, PHBV, PHA, PVA, PCL, PGA) and combined granulation.
