| One twin screw extruder | |
| Production volume | According to the raw material process formula |
| Screw diameter | Φ20 |
| Aspect ratio | 1: 40 options available |
| Screw rotation | Parallel and in the same direction |
| screw speed | 0-120rpm |
| Screw | The core shaft is made of 40CrNiMoAIA chromium molybdenum alloy tool steel, and the threaded components are made of W6Mo5CR4V2 wear-resistant alloy steel with a hardness of HRC60. It has conveying blocks, mixing blocks, shearing blocks, mixing blocks, kneading blocks, counter current blocks, and modular series components that can be combined according to any material ratio. To meet the needs of different extrusion processes. |
| Cylinder body | The 5-section material cylinder is made of 38CrMoAlA nitride steel forgings, lined with wear-resistant alloy sleeves, with a hardness of HRC60. It has been treated with nitriding, quenching and ultra precision grinding processes, and the surface roughness is Ra ≤ 0.4 μ m, which is wear-resistant and corrosion-resistant. |
| Heating zone | Cast aluminum heater in zone 5 of the cylinder, heater in zone 1 of the machine head, with a heating power of 1kw per section, covered with a safety hood. |
| Cooling zone | The entire cylinder adopts a soft water circulation cooling system, and the flow rate of cooling water in each section can be adjusted. It is equipped with a self-priming circulating water pump, a 304 stainless steel water storage tank, inlet and outlet pipelines, and electromagnetic valves and other components. Each segment of the cylinder unit can be independently temperature controlled and cooled. |
| Vacuum zone | The water circulation vacuum degassing device is equipped with components such as a water ring vacuum pump, vacuum gauge, and regulating valve, forming a non clogging main exhaust system. |
| Feeding machine | Adopting twin-screw forced feeding, equipped with a horizontal mixer, the feeding is uniform and stable, not easy to bridge, and the feeding speed is adjustable by frequency conversion from 0-50rpm. The feeder is connected to the main unit in a sliding manner, making it easy to clean the screw |
| Head pressure | The working pressure of the machine head is monitored by high-precision temperature and pressure sensors to detect changes in the temperature and pressure of the molten metal in the machine head, and the operation of the host is interlocked and controlled, with overpressure protection function. |
| Granulation mold head | 38 CrMoAlA chromium molybdenum alloy head, with a nitriding hardness of HRC60. The number of strips and granulation diameter can be selected, and there is a built-in fast hinge screen changing device. |
| Gearbox | High speed heavy-duty hard tooth surface gear transmission, integrated structure of gear reduction and torque distribution box, with imported bearings and oil seals for internal transmission components, and oil immersion splash lubrication. |
| Drive motor | Precision heavy-duty gear reduction motor with constant torque power output control. |
| Main frame | The overall frame is welded with steel sections, with a sturdy structure that is not easily deformed. The bottom of the frame is equipped with movable and brake casters, which are easy to install and move. |
| Safety protection | The protection function includes: interlocking of melt pressure with the main engine, providing overpressure alarm protection; The melt temperature is interlocked with the main engine for startup and shutdown protection; The feeding is interlocked with the main engine to protect the starting sequence. |
| electronic control system | PLC programmable color touch screen, human-machine interface operating system, extrusion process can be dynamically displayed and monitored, including temperature control, drive, pressure, and interlocking control functions. |
