Conair Group Inc. has developed high-heat models of its TrueBlend gravimetric batch blender, so processors can now blend resins like ABS, nylon, polycarbonate and PET after they are dried.
High-heat versions of the TrueBlend 100, 250, 500 and 900 blenders offer throughput as high as 3,500 pounds an hour.
Pittsburgh-based Conair will introduce larger models, with throughputs as high as 10,000 pounds an hour, soon.
Until now, processors had to blend the material before drying, but, according to Conair, that meant they ran the risk that some ingredients could separate from the mix during the drying and conveying process.
Conair offers several high-temperature packages, depending on the application. All include components like load cells, level sensors and air cylinders specifically designed to stand up to temperatures of 375°F and higher. Electronic components are isolated from the high temperatures.
The blenders also can be equipped to blanket the material compartments and mixing chamber with dry air, to prevent moisture from coming back during blending.
