Wet types steam extruder Main Features:
1. The main extruder adopts frequency speed controlling with high automation and stable per-formation.
2. The screws are made of the alloy steel and special craft, durable usage, high pressure, the screw life is longer. Adopting the building block structure and combining willingly according to the different demand.
3. The forced lubrication system, so that it can guarantee the equipment transmission life longer
4. Auto-temperature control system; Make the temperature controlling more direct viewing and the parameter more precise.
5. Self-cleaning, when stopping, it can be cleaned without disassembling
6. According to different screw design rate to Full different technology request.
7. This equipment has the wide material, multi-shape products and flexible collocations. We can produce the different products according to the different models and collocations.
SLG Series Double-screw Extruder is mainly composed by the following parts:
A Feeding System B Extruding System C Cutting System
D Heating System E Lubrication System F Driving System
G Control System
A Feeding System
Feeding system is fixed on distribution box, feeding raw material by screw rotation. The speed is adjustable. This system Is composed by screw, raw material hopper, mixer, driving part.
Motor model MBK07-Y0.55-C5
Screw diameter: Φ 65mm , Φ 70mm , Φ 85mm
Screw speed: 0~150rpm
B Extruding System
The main part of extruding system is two screws and barrel. The rotation directions of the two screws are same: anti-clock. During processing, the two screws scraping the materials stick on the other screws and pushed forward. The screws are composed by seven sections. During the raw material pushing forward, the raw material contact much more with the barrel, and easy absorb the heat energy from the barrel. At the last section of the screws, the raw material will increase inner energy and finished the extrusion. The screws are easy to replace.
C Cutting System
Cutting system is composed by motor, knife and belt. The knife frame is fixed on the mould part, driven by motor, the foods is cut by the knife. More than 20 shapes of moulds available for choice.
D Heating System
Heating system is divided to 2-5 section, every section has two infra-red heater. The power is 2kw for each heater. The temperature of each section is adjustable.
E Lubrication System
This system is composed by gear pump, oil tank, oil pipes. It's used for lubrication and
cooling for every rotating parts.
Model of gear pump: BBG-6
F Driving System
Attached drawing III is for SLG series double screw extruders. The power starts from main motor, after one pair of belt and I=9:1 reducer, it is then divided to two screws which rotate the same direction. Gear Z24 and Z50 are grawed outside, it belongs to belt driving system. The reducing ration of this driving system is: I=(Φ270×24/Φ250×50)×9=4.67. The speed adjustment is by frequency inverter, Reliable and wide range for adjustment.
G Control System
All the extruder is concentrated by console. Easy for operation, All extruders have self-protection device and habitus indication meter.
Protection grade: IP44
Safety protection: ground (less than 4Ω)
