Contract Manufacturing Experience

Why Is Sieving Important for Excipients? Pharmaceutical manufacturing demands high precision and consistency. Excipients are typically sized to meet tight particle specifications—often below 180 microns—to promote reliable flowability, compressibility, and uniformity in tablet and capsule formulations. Oversized particles can result in dosing inconsistencies, while excess fines may interfere with disintegration or clog tablet press tooling. Static-prone, hygroscopic, or irregularly shaped powders can cause screen blinding in conventional sieving systems.

Elcan Industries works with pharmaceutical companies to sieve a wide range of sensitive, low-bulk density excipient powders. Our Hi-Sifter screening machine uses vertical energy to deliver sharp particle size cuts—commonly down to 44 microns or finer—without screen blinding or throughput issues. This method is particularly effective for excipients like MCC, maltitol, and mannitol, which are prone to agglomeration and poor flow.

For finer separations or when screen limitations exist, our Elbow Jet Air Classifier allows for classification down to 10 microns. When product purity is critical, our CG Electromagnetic Separator removes trace ferrous contamination, meeting the demands of pharmaceutical and cleanroom-grade applications.
