Live bottom extruder for processing sealants and mastics
When processing entire batches of butyl, sealants, and other mastics, traditional methods often require pre-sizing of batches and careful material handling to achieve optimal results. This results in added costs and complexity in the manufacturing process.

Efficiently process entire loads with dual control
The Live Bottom Feeder Extruder by The Bonnot Company streamlines the processing of large material batches directly from mixers, eliminating the need for pre-sizing. Featuring dual drives for separate feed and extrusion control, the extruder is equipped with multiple temperature zones, including controlled temperature screws. Customizable feed beds align with specific batch sizes, and the machine can be configured for either right or left-hand facility layouts. Optional hydraulic batch loading further simplifies operation. Models such as the RS 6 Series LB and RS 8 Series LB offer outputs ranging from 1,000 to 4,500 lbs/hour. The extruders are powered by high torque motors—25 HP for feeding and 75 HP for extrusion in the RS 6, and 40 HP and 100 HP respectively for the RS 8.
