Description

The conical twin-screw extruder gearbox has two parts, the drive gearbox and the distribution box, the two conical twin-screw will be connected to the distribution box, the conical twin-screw extruder also uses a twin-screw feeder, it is more Stable and accurate.

We use aluminum ceramic and aluminum heaters on conical twin-screw extruders, all heaters have an external protective cover to avoid personal injury, and water circulation cooling is installed in the feeding area to prevent the PVC material from being blocked, because the heating power will Transfer from the screw barrel to the feed zone.

In addition, we have a vacuum system with good performance that can draw moisture and air from the barrel; it will improve the quality of plastic products; all cables have been selected with larger diameters to avoid unstable voltage and current. For special voltages, like 220V, we’ll use double-diameter cables because the current is much higher than the others. The details of our conical twin screw extruders will be considered as we have manufactured all voltage extruders.

The conical twin-screw extruder consists of the following parts:

-Barrel screw
-Gear transmission system
– quantitative feeding
-Vacuum exhaust
– Heating, cooling and electrical control elements, etc.
Although this is the basic structure of a conical twin screw extruder, there can be more or fewer components depending on the application requirements. Conical twin screw extruders are generally reliable and efficient machines for the manufacturing process.

How is the structure of a conical twin-screw extruder different from other types of twin-screw extruders?
The conical twin-screw extruder has two parts in the gear box, which are the gear box and the independent box of the two screws. In addition to this, the rotational speed of the conical twin-screw extruder is large. Therefore, the extruder can also work at low speed.

Since its twin screw is conical, which affects the high pressure of the die, we can use more caco3 in the recipe to reduce production costs.

Finally, there is also a vacuum system inside the conical twin screw extruder. This vacuum system can enhance the plasticization of PVC powder.

Conical twin-screw extruder is the most popular twin-screw extruder in China and even in the world.
