Particle size conditioning and screening
Milling, Sieving & Delumping System
Milling, sieving and delumping systems for pharmaceutical powders before blending, granulation, compression or packing.
Short Answer
A milling, sieving and delumping system conditions powders before downstream processing by reducing lumps, controlling particle size and screening oversized or foreign material.

What Information Is Needed For Quotation
A clearer URS and layout package helps the engineering team confirm equipment scope, capacity assumptions, containment expectations and documentation needs.
Product name, powder properties, bulk density, particle size range and flowability notes.
Required capacity per batch or per hour, target transfer distance and elevation.
Process layout, room classification expectations and upstream/downstream equipment interfaces.
Containment, dust extraction, cleaning, material contact and documentation expectations.
Utilities, control preference, automation scope and FAT/SAT/IQ/OQ support requirements.

FAQ
Frequently Asked Questions
How is a mill or sifter selected?+
Selection depends on particle size target, powder behavior, heat sensitivity, capacity, containment need and cleaning method.
Can milling and sieving be combined in one route?+
Yes. A line can combine delumping, cone milling, sieving and transfer when the process flow requires sequential conditioning.
Can the solution be adapted to an existing production room?+
Yes. Layouts can be reviewed around existing rooms, ceiling height, operator access, utilities and equipment interfaces before a final proposal is prepared.

How To Choose a Pharmaceutical Vibro Sifter
Choose a pharmaceutical vibro sifter by confirming the screening purpose, mesh size, capacity, powder behavior, containment level, feeding method and cleaning expectations.
Read guideCone Mill vs Hammer Mill
Cone mills are often used for controlled delumping and granule sizing, while hammer mills are used for more aggressive size reduction. Selection depends on target particle size, heat sensitivity, containment and cleaning needs.
