Compounding extruder BP series

parallel twin-screw

BP Twin Screw B&P Littleford’s sustained focus on offering proven compounding and mixing technology that is reliable, flexible to operate, and easy to maintain resulted in the enhanced BP series extruders. The BP series extruders have larger free volume per unit length for a given diameter twin screw extruder. Owing to their inherent deeper channel screw geometry, their mixing operation is characterized by narrow residence time distribution, high rate of melt surface renewal, low gas speeds and low shear energy input. They are therefore widely used for highly filled compounds, TPE preparation, and in the reaction, concentration and residual degassing of various polymers. BP Series Extruder Features In addition to all the conventional advantages of twin-screw systems – including a more homogenous melt, efficient mixing, and continuous operation – the BP Series Extruders feature: Intermeshing, self-wiping screw design for reliable, efficient mixing operation. Unique OD/ID ratio for deeper flights and high free volume availability, resulting in higher output. High torque capability of the entire drive train for enhanced specific torque availability. Optional hinged clamshell barrel design for easy access during maintenance, changeover, and cleaning. Wide range of configuration options and supporting ancillary equipment such as high speed side feeders, vacuum vent stuffers, and customized control system to suit the demands of your application.
