Case study: Circular vibrating separator for plastic pellets

Russell Finex helps a manufacturer of custom colour concentrate and additives to boost productivity with a vibratory round separator

Accurate Color & Compounding (ACC), a manufacturer of custom colour concentrate and additives for the plastics industry, reached new levels of productivity and growth by turning to the innovative separating equipment of Russell Finex.

Headquartered in Aurora, a suburb of Chicago (US), the company had relied on operator inspection and hand screeners to check the quality of their colour concentrate and additives.

ACC sought a more efficient solution, and as a final quality check before drying, the company trialled the 40” Finex Separator from Russell Finex. Pleased with the results, they purchased the machine along with six more.

Sieving efficiency

This vibrating separator was chosen as the unique rubber suspension system allows much higher forces to be put into the machine and focuses the majority of the energy on the screen itself.

The adjustable weight system of the vibrator assembly creates a more finely-tuned and vigorous action, significantly raising sieving efficiency and running as standard at 1800 rpm.

The new separators have boosted production uptime as well, as Jason Yelm, Plant Manager, commented. “They’ve eliminated stoppages in our dryer caused by oversize and reduced the need to change die heads by 30 to 40%, minimising downtime,” he said. 

Yelm added: “By setting up specific mesh sizes for customers, we provide the exact pellet size they want with every production run; and we let runs go longer since we reliably filter out any undesirably sized pellets.”
