Speciality separation methods: mechanical air classification, air classifier milling, screening, and more.


Custom Processing Services — bring us a challenge; we’ll show you the best solution

Our specialty separation services — mechanical air classification, air classifier milling, screening — and equipment match your unique particle separation needs. Our repackaging services allow for personalization of finished packages and direct shipment from our factory. Plus, lean on us for analytical lab, engineering, and logistical services.


Screening and Classification

We offer various particle separation methods — mechanical air classification and air classifier milling — as well as screening: single or multiple decks; stand alone or part of a sizing system; in conjunction with blending and/or repackaging (see below). Our technical staff helps you select the best equipment for your unique particle separation needs.



We’ll repack your materials in concert with our size reduction or blending work, or even on a stand-alone basis. This allows you to personalize your packages and facilitate direct shipment from our factory to your clients. Equipment and techniques include automated bagging equipment; paper or paper with polyethylene barriers; super sacks; drums; gaylord boxes; pails; stretch wrapping; customer- or CPS-supplied packaging; and stenciling and labeling to your specifications.


Surface Treatment

Using the same application, we can coat particles a low percentage with friendly oils to de-dust micronized materials. The most commonly used surface modifiers — silane coupling agents, or silanes — have the characteristic property to bond together both inorganic and organic dissimilar materials. Surface conditioning methods are used in conjunction with the silanization of filler particles, glass fibers, and ceramic surfaces, emphasizing the importance of the role of a silane coupling agent in the promotion of adhesion.


Logistical Services

Beyond particle technology, we also serve as your resource for moving product to where you need it. We maximize efficiencies and achieve optimal pricing with your bottom line in mind. Our Southeastern Pennsylvania locations are near major transportation routes to get your deliveries on the road easily and quickly. We also offer warehousing services, complete with warehouse agreements, at a competitive price point.


Engineering Services

Our experienced engineering team focuses on improving current processes as well as implementing new project initiatives. We’re with you, a guide from initial concept to pilot testing to implementation and evaluation. We can also engineer new processes complete with installation on- or off-site.
