3. Applicable for wet and lightweight material
4. Below 5% moisture, suitable to extruder

Ⅱ. Rigid plastic flakes granulating recycling machine line detail list:

Cold-strand granulating way, die-face cutting way also available with rich experience, based on raw material condition.

Ⅲ. Detailed description for rigid plastic flakes granulating recycling machine line:

Less power consumption cost per kilogram, high output, reduced floor space occupation and operator attendance

1. Screw loader uploads the raw material by timer
2. Single screw extruder is controlled by inverter
3. Different L/D for different material
4. Nature degassing, vacuum degassing adopting for moisture
5. Water-ring/cold-strand/die-face cutting for perfect pellets shape

Rigid plastic flakes granulating recycling machine line’s technical parameter

Machine list

Screw loader

• U-type screw feeder
• Frequency conversion speed regulation ensures that the feeding amount is consistent with the extrusion amount and no blocking occurs.
• Part of contacting material: stainless steel 304
• Quantitative feeding to ensure stable feeding
• Adopt material limit device

Single screw extruder (First stage)

1^st extrusion, 1^st filtering

1）Gearbox: high quality Chinese brands or based on customer’s request

2）Frequency inverter: Siemens brand

3) Screw & barrel: 38CrMoAl, Nitride with thickness 0.4 ~ 0.7 mm, Polish

4) Heater: Ceramics + stainless steel cover

5) Vacuum pump exhaust, double exhaust

6) Self-protective system:

Over current protective of motor

Over pressure protective of screw

Over temperature protective of motor

Low & over temperature control of extruder

Screw & barrel are specially designed by our engineer according to decades years’ experience for good plasticizing effect & capacity.

Screen changer

Multiple choices for different materials.

• Material for mold body: 40Cr
• Nitriding and polishing of runner surface
• Pressure and temperature control
• When pressure is nearly reach alarm value, hydraulically change to another station.
• High filtering effect, realizing non-stop screen changing
• No leakage, automatic gap compensation

Single screw extruder (Second stage)

2^nd extrusion, 2^nd filtering, to achieve better granule quality

Water ring cutting system

Quantity of Blade: 2-4, SKD-11

Speed controlled by inverter

Material of die head: 38CrMoAlA

Material of water ring cover: Stainless steel 304

Horizontal design with linear guide, easy operation and maintenance.

Pneumatic adjustment, to make cutting blades and die-face soft touch, in order to achieve 100% contact between the blade and die head, to avoid die face damaged.

Dewatering Vibrator

1.Linear vibrating screen uses vibrating motor as the vibration source, so that the pellets are thrown up on the screen, and move linearly forward. Several sizes of screens are equipped for pellets discharging from their respective outlets.

2.Linear screen fully enclosed structure, no dust and overflow, automatic discharge, etc., more suitable for 24-hour assembly line operation.

3.Linear screen by low energy consumption, high output, simple structure and easy maintenance.

4.Combination of filtration and dehydration, high efficiency and power saving.
