Single Screw Extruder

<br /> Nanjing Gorray has developed single screw extruder with some new features, most of which are targeted for energy-saving, high productivity and easy control. <br /><br /><br /> u00b7Advanced screw design to optimize the output and keep melt at lower temperature;<br /><br /><br /> u00b7Overload protection by reliable flexible coupling;<br /><br /><br /> u00b7Accurate temperature control system;<br /><br /><br /> u00b7Convenient erection & adjustment<br /><br /><br /> Single screw extruder is one of the core extrusion equipments in polymer processing and is also a key component in many other processing operations. The preliminary aim of a single screw extruder is to build pressure in the polymer melt. With sufficient pressure the melt can be extruded through a die or injected into a mold. A single screw extruder brings in solids in either pellet or powder form and melts them as well as building the pressure.<br /><br /><br /> Thus a single screw extruder is widely used for direct extrusions such as sheet extrusion, film extrusion,pipe extrusion, tube extrusion and profile extrusion.<br /><br /><br /> In some cases, those pro-water polymers such as PET, PMMA, PC need venting or vacuum. So a high efficiency venting system will be furnished. In plastic recycling process, venting of a single screw extruder turns out to be a necessity.<br /><br /><br /> A single screw extruder can be a good match for twin screw extruder, which is herein referred to as dual stage extrusion anjing Gorray, a new experienced extruder supplier in China.<br /><br /><br /><br /> Single Screw Extruder without Venting<br /> Product Specification / Models Specifications <br /><br /> <br /> <br /> <br /> <br /> Model<br /> <br /> <br /> <br /> <br /> Screw Diameter(mm)<br /> <br /> <br /> <br /> <br /> L/D Ratio<br /> <br /> <br /> <br /> <br /> RPM<br /> <br /> <br /> <br /> <br /> Motor Power(kw)<br /> <br /> <br /> <br /> <br /> Capacity (kg/h)<br /> <br /> <br /> <br /> <br /> <br /> <br /> SJ20<br /> <br /> <br /> <br /> <br /> 20<br /> <br /> <br /> <br /> <br /> 28-32<br /> <br /> <br /> <br /> <br /> 150<br /> <br /> <br /> <br /> <br /> 3<br /> <br /> <br /> <br /> <br /> 3-10<br /> <br /> <br /> <br /> <br /> <br /> <br /> SJ30<br /> <br /> <br /> <br /> <br /> 30<br /> <br /> <br /> <br /> <br /> 28-32<br /> <br /> <br /> <br /> <br /> 150<br /> <br /> <br /> <br /> <br /> 11<br /> <br /> <br /> <br /> <br /> 10-30<br /> <br /> <br /> <br /> <br /> <br /> <br /> SJ45<br /> <br /> <br /> <br /> <br /> 45<br /> <br /> <br /> <br /> <br /> 28-32<br /> <br /> <br /> <br /> <br /> 120<br /> <br /> <br /> <br /> <br /> 30<br /> <br /> <br /> <br /> <br /> 30-60<br /> <br /> <br /> <br /> <br /> <br /> <br /> SJ65<br /> <br /> <br /> <br /> <br /> 65<br /> <br /> <br /> <br /> <br /> 28-32<br /> <br /> <br /> <br /> <br /> 93<br /> <br /> <br /> <br /> <br /> 55<br /> <br /> <br /> <br /> <br /> 40-120<br /> <br /> <br /> <br /> <br /> <br /> <br /> SJ90<br /> <br /> <br /> <br /> <br /> 90<br /> <br /> <br /> <br /> <br /> 28-32<br /> <br /> <br /> <br /> <br /> 93<br /> <br /> <br /> <br /> <br /> 90<br /> <br /> <br /> <br /> <br /> 120-280<br /> <br /> <br /> <br /> <br /> <br /> <br /> SJ120<br /> <br /> <br /> <br /> <br /> 120<br /> <br /> <br /> <br /> <br /> 28-32<br /> <br /> <br /> <br /> <br /> 93<br /> <br /> <br /> <br /> <br /> 132<br /> <br /> <br /> <br /> <br /> 200-450<br /> <br /> <br /> <br /> <br /> <br /> <br /> SJ150<br /> <br /> <br /> <br /> <br /> 150<br /> <br /> <br /> <br /> <br /> 28-32<br /> <br /> <br /> <br /> <br /> 75<br /> <br /> <br /> <br /> <br /> 220<br /> <br /> <br /> <br /> <br /> 400-600<br /> <br /> <br /> <br /> <br /> <br /> <br /> SJ180<br /> <br /> <br /> <br /> <br /> 180<br /> <br /> <br /> <br /> <br /> 28-32<br /> <br /> <br /> <br /> <br /> 75<br /> <br /> <br /> <br /> <br /> 315<br /> <br /> <br /> <br /> <br /> 500-800<br /> <br /> <br /> <br /> <br /> <br /> <br /> SJ200<br /> <br /> <br /> <br /> <br /> 200<br /> <br />
