Features of Kailite Conical Twin Screw Extruder
1. Our conical China 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, 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.
4. The same direction rotation achieves the same distance gearing match which improve screw self-control and manufacturing ability.
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.
Conical Twin Screw Extruder Working Principle
1. Turn on the power. Adjust the temperature controller to a certain temperature and heat to temperature according to the process temperature controller to keep the material in the barrel soft for
3 hours, and then adjust the temperature controller for process temperature control.
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.
3. Turn on the auxiliary feeder, tractor, and cutting machine.
Difference Between Single Screw and Twin Screw Extruder
1. The 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 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.
3. Compared with single screw extruder, conical china double screw extruder can provide higher process productivity.
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 china conical dual screw mixer has complex operation and higher process control requirements than single-screw extruders, simple operation and simple control process.
What is Twin Screw Extruder
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.
Twin Screw Extruder Process
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, it's different from the teeth style
extruder, 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 for Sale
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.
The Kailite main products include plastic machinery series: extruder, plastic pipe production line, plastic sheet/sheet equipment, plastic pipe extrusion line, wood-plastic equipment, plastic
recycling granulator, plastic crusher, etc.
