Description

Sieving Multi Mill operates on the principle of impact, shear, and attrition for size reduction, combined with mechanical sieving for classification. Material is fed into the chamber where high-speed rotating blades strike and propel it against the chamber walls and screens. This “top-down” approach disintegrates coarse particles into finer ones via mechanical energy. Particles smaller than the screen aperture pass through radially or tangentially for discharge, while larger ones recirculate for further milling. The process ensures a narrow particle size distribution (PSD) by controlling rotor speed, screen size, and feed rate.

Limitations: Not ideal for very sticky or oily materials; requires screen changes for different PSDs.

Customization: Options include vacuum feeding, jacketed chambers for cooling, or explosion-proof designs for volatiles.

Trends (as of 2025): Integration with continuous manufacturing lines and AI-monitored PSD for real-time adjustments.

Advantages of Sieving Multi Mill

Versatility: Handles wet/dry materials; supports granulation, shredding, chopping, and mixing in one unit.

Precision: Interchangeable sieves ensure narrow PSD and high uniformity, reducing downstream issues like segregation.

Efficiency: High throughput; 50% faster than conventional mills for low-density materials.

Compact Design: Small footprint suits cleanrooms; easy mobility and integration with lifting columns.

Safety/Hygiene: Low noise, easy disassembly for CIP, and GMP-compliant with minimal dust generation.

Cost-Effective: Low maintenance, energy-efficient, and scalable from lab (5 kg) to production (1,000 kg) batches.

Safety and Validation Considerations of Sieving Multi Mill

Safety: Enclosed chamber with interlocks, guards, and emergency stops; vibration dampers reduce noise and wear.

Validation: IQ/OQ/PQ tests for PSD consistency, throughput at 30-80% loads, and cleaning efficacy.

Maintenance: Inspect blades/screens quarterly; ensure oil-free operation to avoid contamination.

FAQ for Sieving Multi Mill

What is a Sieving Multi Mill and what is it used for?

The Sieving Multi Mill is a versatile, high-speed size reduction and sieving machine that combines milling with mechanical sieving for precise particle size control. It is designed for granulating, pulverizing, shredding, and classifying both wet and dry materials. It is widely used in Pharmaceutical, Ayurvedic, Herbal, Nutraceutical, Biotech, and Cosmetic industries to achieve narrow particle size distribution (PSD) for APIs, excipients, granules, and herbal powders while meeting cGMP standards.

How does the Sieving Multi Mill work?

Material is fed through the SS hopper into the milling chamber. A high-speed rotor with swing-type beaters (knife & impact edges) and scrapper blades subjects the material to impact, shear, and attrition forces. Particles are thrown against the perforated screen; those smaller than the screen aperture pass through, while larger particles continue to be milled until they achieve the desired size. The reversible rotor direction and variable speed ensure optimal performance.

Mirror-polished stainless steel surfaces and the absence of dead corners minimize residue. This enables quick product changeovers and supports strict GMP cleaning validation requirements.
