Key Blending Considerations in Wood-Plastic Composites

With the diversity of organic components used in wood/plastic composite processing, there is no single answer to reliably handling these potentially difficult materials.Pre-purchase testing helps tiles in the terrace design determine the optimal combination of bin design, agitation and other flow aid strategies for the specific material in use.Coperion K-Tron's fully-equipped testing facilities are available to evaluate your materials and determine the optimal combination of equipment components to assure the highest level of accuracy and reliability. Computerized performance test reports document equipment performance.Feeder design and how to waterproof a wall from outside wood agitation solutions are also key to handling difficult bulk materials. Coperion K-Tron offers over 30 years of experience in material handling technology.As the illustration at right shows, lengthy performance timescales permit a given blending accuracy to be attained with a low performance weighing system.However, to achieve the same accuracy in the short interval characteristic of compounding wood over concrete stair and extrusion operations, a much higher weighing performance is required. Additional important blending system considerations in wood/plastic composite processing include control and weigh system insensitivity to environmental disturbances, and the ability to reliably handle/control difficult organic components.
