The Double Roll Extruder Machine (DRE) is a machine that extrudes polymers into continuous strands. It uses two rolls of different sizes to apply pressure on the polymer mixture, which helps in the formation of fibers and other products. DRE has been widely used in the production of various types of plastics such as polyethylene, polypropylene, and polyvinyl chloride.

The Double Roll Extrusion process begins with the mixing of raw materials and additives, followed by the introduction of the polymer melt into the first roll. The polymer melt is then pressed against the inner surface of the first roll, causing it to be pulled through the gap between the two rolls. This causes the polymer melt to flow into the second roll, where it is again pushed against the outer surface of the second roll.

During this process, the material being processed is subjected to high temperature and pressure, which results in the formation of fibers and other products. The size of the rolls can also affect the final product, so they must be carefully selected based on the desired characteristics of the finished product.

In addition to its ability to produce fibers, DRE can also be used for other applications, such as the production of films and films, as well as the manufacture of non-woven fabrics. However, it's important to note that the specific type of DRE required will depend on the particular application and the specific needs of the manufacturer or end-user.
