Twin Screw roller head extruder represents a significant advancement over the sheeting mill and dump mill technique used in traditional mixing lines that consumes more energy and does not produce half the required quality. With a twin screw roller head extruder, the mixed compound is transferred directly from the internal mixer into the machinery to be converted into high quality smooth, seamless rubber sheets that are then fed into the batch-off cooling machine. It is also far safer than the traditional mill apparatus and also far more reliable.
Once the compound is fed into the twin screw roller head extruder, it is heated up with the help of screws and heaters present in the machine. Heated rubber is then molded into specified shapes and extruded onto the cooling line. It comprises of a highly specialized twin screw extruder with an inclined roller-head and is widely used in manufacturing processes related to the production of industrial rubber goods, belts and hose as well as tire manufacturing.
Twin Screw roller head extruder offers many advantages over traditional dump mill rubber production. It has a more diverse application portfolio and can be used for industries as diverse as tire production and industrial rubber production. But its biggest advantage lies in the fact that it offers a significant energy saving over traditional machinery. By avoiding the use of double machinery for the mixing and cutting of rubber into shapes twin screw roller head extruder enables organizations to reduce energy consumption by more than 15%. Also the use of twin roller extractors helps reduce labor costs as it eliminates the need for manually performing rubber sheeting function. Reduced labor leads to fewer accidents and less wage cost which all adds upto lower production costs and ultimately lower rubber cost.
One reason why twin screw roller head extruder is so popular is the fact that is produces higher quality rubber by reducing exposure of rubber to air and dirt. In a traditional production environment, rubber travels from the internal mixer onto the sheeting machinery and there is the risk of contamination due to the exposure of the rubber to outside air and the dirt, moisture and pollutants present therein. In a twin screw roller head extruder, since the mixing and sheeting process is performed by a single piece of equipment in a closed environment, there is no contamination due to exposure leading to a higher quality output of rubber.
