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)

1st extrusion, 1st 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)

2nd extrusion, 2nd 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.
