Powder screening and classification
Pharmaceutical Vibro Sifter
Pharmaceutical vibro sifter for safety screening, grading and powder conditioning before blending, granulation, compression or packing.
Short Answer
A pharmaceutical vibro sifter screens powders to remove oversize particles, support particle consistency and protect downstream equipment.
Process position
Process Position
The sifter is placed after bag dumping, dispensing, milling or drying, and before blending, granulation, tablet compression, encapsulation or packing.

Quotation input
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 screen mesh selected?+
Mesh selection depends on target particle size, powder behavior, capacity, deblinding need and acceptable product loss.
Can a vibro sifter be used inline?+
Yes. Inline feeding and discharge can be arranged with vacuum conveying, flexible connectors or gravity transfer.
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.
