RG-500 Additive Feeder

The RG-500 is Colourmate's larger additive feeder. This feeder is engineered to introduce higher volume additives such as reground plastics, and is capable of throughputs of up to 500 lbs per hour. The RG-500 is ideally suited for the feeding of reground plastics due to the large entry from the supply hopper to the widely spaced auger flights, this design reduces the risk of jamming by allowing larger additive particles to flow smoothly through the feeding chamber. 

Designed along the same functional lines as our standard colour additive feeder, the RG-500 exhibits many features which make it as durable, accurate, and easy to clean out between material changes. The large stainless steel hopper is equipped with a side mounted chute to facilitate quick draining, and the swing away motor allows the operator immediate access to Colourmate's exclusive integral auger/barrel cartridge. With the slackening of a single knob, the auger cartridge can be removed as a unit, for easy cleanout and quick alignment. The machined nylon auger sleeve along with the stainless steel hopper are easily cleaned, and provide durable non corrosive surfaces which keep the additives free from contamination.
