Industries we work with
Frequently Asked Questions (FAQs)
What types of plastic materials can VibraScreener's pellet classifiers process?
Our pellet classifiers handle commodity resins like polyethylene, polypropylene, and PVC, engineering plastics such as nylon, and legacy materials including Bakelite and celluloid. Contact us if you’re working with a resin not listed here.
What's the difference between dewatering and check screening for plastic pellets?
Dewatering removes residual water from pellets after a wet cooling or cutting process, while check screening runs sized plastic pellets through a final pass to catch stray fines or clumps. Many customers run both applications on the same line.
How does VibraScreener's suspension technology increase pellet screening capacity?
Robust support housings paired with modern suspension technology let us apply higher force to the screening area without needing a larger screen diameter. That means a plant can often increase screening capacity on an existing footprint instead of upgrading equipment.
Can plastic pellet screening equipment remove fines and dust from resin before molding?
Yes, screening plastic pellet powders is one of the core applications, designed to separate fine dust and undersized particles from good pellets before molding. Fines left in the feed stream can cause inconsistent melt flow and surface defects.
What accessories help prevent screen blinding when running plastic pellets?
Deblinding accessories, including bouncing ball assemblies that sit beneath the mesh, knock loose material out of the screen openings during operation. Ask your VibraScreener representative about adding one when you order a classifier.
Do you offer free testing to find the right screen mesh for my plastic pellets?
Yes, our Charlotte, North Carolina test lab analyzes your actual material at no cost to determine average pellet size, oversize percentage, and material behavior. That testing step is what lets us match you with the right plastic pellet separator equipment the first time.
Can plastic pellet classifiers also remove metal contamination before molding?
Our plastic pellet classifiers are engineered for size-based separation, sorting pellets and oversize material by mesh aperture rather than detecting metal. Metal contamination removal is typically handled by a separate inline metal detector installed alongside the screening equipment.
What's the difference between a plastic pellet classifier and a plastic pellet separator?
In practice, both terms describe the same core function, and VibraScreener uses plastic pellet separator and classifier interchangeably depending on machine configuration. See our Dynamic Screener™ and Ranger Separator™ product pages for the equipment behind these classifications.
