Interchangeable augers and barrels. No matter what throughput you need, we have a metering auger that’s right for the job. Just swing away the motor and the auger slides out. Release a retainer and remove the mating barrel. And the unique, single end bearing design gives you the rigidity necessary for precise, repeatable shot volumes, cycle after cycle, or continuously.

Set up is simple and quick using the sampling outlet provided for feed rate calibration. The .75 cu. ft. bin comes with sight glass and slide gate, and is clamp mounted for convenience. A rapid drain port is provided, too. And up to four feeders can be swing locked into place on one machine throat adapter. Standard variable speed 110 volt controls are remote mounted.

These series of crammer feeders are force feeding devices that are designed to compact fluffy materials at the extruder screw to provide a uniform density and relatively consistent head pressure.

Our crammer feeders employ the use of a Flux Vector drive, a true torque device which enables the system to feed up to a 50% fluff/pellet blend with a consistent material density at the extruder throat. The benefits of this crammer feeder include true cramming action which provides relatively constant head pressure throughout the range of normal extruder needs.
