Rubber Extruders

Our rubber extruders (feeders), can ingest full or partial bales of a wide range of rubbers including natural & EPDM

Rubber Bale Feeders are used for pelletizing or directly feeding a compounding extruder where the high viscosity rubber is a component in the formulation.

In many plants a granulating system is currently used to grind the bale in order to introduce it into a compounding extruder. Utilizing a Bonnot Rubber Bale Feeder the entire bale is placed in the feeder, digested and accurately metered into the compounding extruder on a continual basis. The high cost and maintenance of a granulating system is eliminated. This also eliminates the need for additives such as talc.
