twin-screw extruder
Product description

Parallel twin-screw extruder is a kind of high-efficiency compounding and extruding equipment. Its core section is composed of “00”type barrel and two screws, which mesh with each other. Parallel twin-screw extruder also has driving system, control system and control system, feeding system.It forms a kind of special extruding, granulation and shaping processing equipment.

Parallel Twin-screw Extruder

The parallel twin-screw stem and barrel adopts building type design principle to change the length of the barrel.It chooses different screw stem parts to assemble the line according to material characteristics, so as to get the best work condition and max function. Parallel twin-screw has good mixing, separating, dewatering and self-cleaning functions to avoid the materials wrapping the axle, caking in the extruding process. With the rotation of the screw, the surface of the materials continuously change, helps the volatile matter dewater, treat, and etc.

What is paralle twin-screw extruder?

Parallel Twin-screw

Parallel twin screw extruder is used extensively for mixing, compounding, or reacting polymeric materials. The flexibility of twin screw extrusion equipment allows this operation to be designed specifically for the formulation being processed. For example, the two screws may be corotating or counterrotating, intermeshing or nonintermeshing. In addition, the configurations of the parallel twin-screw themselves may be varied using forward conveying elements, reverse conveying elements, kneading blocks, and other designs in order to achieve particular mixing characteristics.

What benefits we can get from parallel twin-screw extruder?

1.High torque, high speed

The parallel twin-screw extruder machine has developed to new models with higher torque, higher speed and lower consumption, and the high-speed brings the high productivity. Therefore, it is special in processing materials of high viscosity and heat sensitive.

2.Increase labor efficiency

When repairing or in a maintenance of machines, just loosen some bolts on split parallel twin-screw extruder, turn on worm gearbox handle and lift the upper half of the barrel to open the whole barrel, compared to the ordinary parallel twin-screw extruders, which are required to remove heating and cooling systems first, and then pull out the whole screw, the split parallel twin-screw extruder can shorten the repair time and lower the labor intensity.

3.Know the wearing parts conditions timely

Parallel twin-screw extruder makes it easier to know the wearing conditions of screw components and barrel inner liner, so to repair or remove the worn parts in time, instead of causing problems on the extruded products, and resulting in unnecessary waste.

4.Reduce production cost

When in the manufacture of masterbatch, it often requires to change colors, or to change products if necessary. This can be simpler. Quickly opening the barrel of the split twin screw extruder to have manual cleaning instead of using detergent, so to save the cost.
