Industrial rubber extruder machine with two motors, metal frame, and rollers mounted on a platform with caster wheels. The unit is labeled “Bonnot” and features yellow safety covers on various parts for enhanced operator protection.

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.
