Product Details

1. Gentle moulding design of SJSZ Conical Twin Screw Extruder guarantees the quality of the matter.

2. Dependable and valid design theory guarantees the dependable operation of extruding. The special big torque drive system, gear tooth and shaft are high-intensity alloy steel which are treated by the cementite and tooth grinding.

3. The fresh development screw may be applicable to the dispensation that has a great amount of padding and guarantee the degree of filling up and the optimum stuff distributing of material in a screw.

4. Screw with core temperature regulation unit and well barrel cool guarantees the exact control of technology temperature of the material.

5. Matched with a different standard of pipe die, the auxiliary device is used to extrude different pipe, plate, profile and soft and rigid PVC granulation.

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 conical twin screw extruder china 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 twin screw extruder china 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, twin screw extruder can provide higher process productivity.

4. The twin-screw 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 twin-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 twin-screw extruder has complex operation and higher process control requirements than single-screw extruders, simple operation and simple control process.
