Conical twin-screw extruders are commonly used to modify polymers physically. They may also be employed to extrude moldable items while offering improved feeding capabilities and excellent mixing, venting, and self-cleaning characteristics compared to other screws extruders. Thus, this article will cover everything you should know about the conical twin-screw extruder.

Conical twin-screw extruders are primarily used to plasticize, mix, and extrude SPC or PVC powder. It can make PVC pipes, profiles, plates, sheets, films, and plastic granulation when equipped with auxiliary equipment. In addition, with the advancement of technology, conical twin-screw can now process various powders such as PE, PP, and SPC.

The first and foremost benefit of leveraging the conical twin-screw extruder is its high productivity. For instance, the conical twin-screw extruder can produce a high volume of outputs with fewer inputs and smart controls to achieve better productivity.

Basically, multiple factors improve the machine’s productivity, ranging from utilizing compatible raw materials to intelligent electronic control systems. To mention that, the daily extrusion rate of the 180 conical twin-screw extruders from Boyu, an expert in producing plastic extrusion machines, ranges from 80-100 tons per day, which will bring you a satisfying user experience with higher productivity.

If a machine produces products with varying output quality, it will be a waste of time to select and modify them so that the production costs are increased. A split twin-screw extruder, on the other hand, can overcome this problem due to its consistent performance. Not only that, but it also benefits in terms of cost-effectiveness with a lower failure rate and power-saving features.

While giving consistently high-quality output in large volumes with excellent efficiency, the conical twin-screw extruder has a wide range of applications. It can be applied to the processing of a variety of materials. Some of the significant applications of conical twin-screw production lines include the production of SPC, PVC, and WPC.

High torque and high speed are the overall development trends of conical twin-screw extruders. In this regard, the split twin-screw extruder falls into this category, and its revolutions per minute can reach rather high levels. As a result, it has a lot of advantages when it comes to handling materials with a lot of viscosity or that are heat-sensitive.

Now that you know everything about the conical twin-screw extruder, you should choose the manufacturer wisely. Accordingly, Boyu is a seasoned plastic extruder producer with over two decades of expertise.

1. Our conical twin screw extruder adopts side feeding technology, which improves the integrity of the material and greatly increases the output. The location and shape of the feeding inlet also have a great impact on the feed efficiency. Under the same parameters, the feed area increases, then the output increases. Under the same inlet area of the conical twin screw extruder, the rectangular section has higher feeding efficiency than the circular section. The use of side twin screw feed is also based on this consideration.

2. Kailite conical twin screw extruder has strong self-cleaning ability. Since the two screw sleeves are intertwined, the contact part forms a continuous space curve with uniform clearance. With the synchronous rotation of the two screws, the space curve moves accordingly, forming the self-control effect between the screws. At the same time, the glue on the screw surface is cleaned to ensure no residual material left.

3. The kneading block can mix materials inside. Increasing the number of kneading blocks in the conical twin screw extruder can increase the number of kneading and improve the quality of kneading. The increase of the pressure in the kneading zone increases the kneading resistance, the kneading strength, and significantly improves the kneading quality.

5. Our conical twin screw extruder has strong adaptability. For materials of high viscosity, a shallow groove screw with low shear rates can be adopted during processing. For materials with high shear rate or high screw speed, deep groove screw is more suitable for improving extrusion quality and output.

2. Turn on the host when turning on the host, pay attention to the current of the motor. If the current is too large, the speed cannot be adjusted at this time. Check whether the material in the barrel is softened or whether the extruder is faulty. After waiting for it to be normal, adjust the speed to the speed required to produce the product.

1. The conical twin screw extruder has excellent mixing capabilities because the intermeshing screws and a wide variety of professional screw designs allow precise adjustment of the degree of mixing to control the degree of mixing. On the other hand, the mixing capacity of a single screw extruder is very limited, and a special screw design of conical twin screw exturder is used to restrict the flow rate to enhance mixing.

2. The conical double screw pp extruder can handle a high level of process flexibility and the ability to handle multiple processes, such as melting, mixing, cooking, venting, cooling, etc. However, in the case of a single-screw extruder, the output and screw speed are dependent, and the screw design with multiple tandem processing functions is limited.

4. The conical double screw pp extruder has a relatively high price due to the complex nature of the machine, while the single-screw extruder has a simple structure and low price.

5. The plasticizing capacity of the conical double screw extruder is better and faster. In a single-screw extruder, the granular material stays in the extruder for longer, which slows down the production time.

6. The conical twin screw mixer has complex operation and higher process control requirements than single-screw extruders, simple operation and simple control process.

The different from single screw extruder is that twin screw extruder has two parallel screws put into the barrel. They can drive by the two screws. Usually the extruder close bite and opposite rotary which extrude profile.

Usually the extruder close bite and opposite rotary which extrude profile. The low speed is 10 r/min, the high speed rotary twin screws" is 300-600r/min, twin screw extruder for sales is different from the teeth style extruder, and is nearly to the single extruder principle.

Same direction teeth style conical twin screw mixer includes low speed and high speed. Opposite teeth style twin screws" gap is very small, so it can convey accurate.

Conical twin screw extruder design means conical shape of the twin screws, the work principle is similar. On the basis of the single screw, conical double screw extruder develops twin screw extruder, the low speed extruder has close teeth screw, one screw match the other close cooperation, conjugate screw shape.

Clean itself extruder, high speed extruder has close matched screw edge shape. It can design this screw into quite small screw gap. Make the screw qualify close self-clean function. It named closed same direction self-clean spiral twin screw extruder.
