Twin-screw extruders can be further divided into: parallel twin-screw extruders and conical twin-screw extruders;At present,In Chiana  single-screw extruder is the most widely used, suitable for extrusion processing of general materials. Because the twin-screw extruder has more heat generated by friction, the shearing of the material is relatively uniform, the conveying capacity of the screw is large, the extrusion is relatively stable, and the material stays in the barrel for a long time, so the material is mixed evenly. 

Twin-screw extruder/granulator application

What is the application of twin-screw extruder? Twin-screw extruder is an important equipment in plastic processing machinery. It is not only suitable for extrusion molding and mixing processing of polymer materials, but its use has been expanded to food, feed, electrodes, explosives, building materials, Packaging, pulp, ceramics, chemicals, LED materials and other fields. The high-speed screw of the extruder also brings a series of difficulties to be overcome: the reduction of the residence time of the material in the screw will lead to uneven mixing and plasticization of the material, and the excessive shearing of the material may cause the material to rise sharply and thermally decompose. Difficulties in controlling the stability of the extrudate will cause fluctuations in the geometric dimensions of the extrudate. The accuracy of the related auxiliary devices and control systems must be improved. The increased wear of the screw and barrel requires the use of high wear-resistant and ultra-high wear-resistant materials. Problems such as how to improve its service life under running conditions all need to be solved. The electrical automation control of the extruder in the working process is also developing continuously. The traditional electrical control is realized by the stand-alone automatic instrument respectively. Now it has developed to the touch screen, PLC, Electrical control system composed of temperature control template, frequency conversion speed regulation, etc. Everyone knows that extruders are constantly developing and their uses will become more and more extensive.

Division of distribution (allocation) and dispersion mixing

1. Distributive mixing, so that the melt is divided and recombined, so that the spatial distribution of each component is uniform, mainly through separation, stretching (compression and expansion alternately produced), twisting, fluid flow reorientation and other stress displacement flow. the

2. Dispersion and mixing, to break the components into particles or to make the size of the incompatible two-component dispersed phase reach the required range, which is mainly realized by shear pressure and extension stress.

Conveyor element, threaded

1. Representation: such as "56/56" conveying block, the previous "56" refers to the length of 56MM, and the latter "56" refers to the length of 56MM.

2. Large lead, refers to the pitch of 1.5D~2D

3. Small lead means that the pitch is about 0.4D. the

4. Its usage rules: with the increase of the lead, the extrusion volume of the screw increases, the residence time of the material decreases, and the mixing effect decreases. the

5. The occasions where large lead threads are used, and the occasions where transportation is the main purpose, are beneficial to increase production; heat-sensitive polymers shorten the residence time and reduce degradation; the exhaust is selected (and shallow grooves are also used) to increase the surface area and facilitate exhaust. , volatilization, etc. the

6. In the case of medium-lead thread, the occasion is mainly mixed, with a combination of different working sections that gradually shrink, used for conveying and pressurization. the

7. In the case of using a small lead thread, it is generally gradually reduced in combination. It is used in the conveying section and the homogenizing metering section to increase the pressure and improve the melting; improve the degree of mixing and extrusion stability.
