Frewitt
Milling & Sizing Equipment
Pharmaceutical Milling from Lab to Production Scale
Frewitt is a Swiss manufacturer of precision milling, sizing, and micronizing equipment for the pharmaceutical, chemical, and food industries. Their product range covers the full spectrum of size reduction – from laboratory screening mills through high-capacity production systems and inline delumping solutions.
MHS Pharma represents Frewitt across the Northeast United States, supporting pharmaceutical manufacturers and CDMOs with equipment selection for size reduction applications from development through commercial manufacturing.
Why Frewitt
Swiss Precision Engineering
Frewitt mills are designed and manufactured in Switzerland with tight tolerances and high-quality materials. Consistent, reproducible particle size reduction across the full product range.
Lab-to-Production Scalability
The same milling principle at every scale – lab results translate directly to production output, simplifying process development and reducing scale-up risk.
Containment-Ready
Full containment options available across the product line for high-potency compound processing. Integrated glove port access, continuous liner discharge, and validated OEB4/OEB5 configurations.
Flexible Technology Platform
Conical screen mills, hammer mills, and pin mills available in interchangeable configurations. One drive unit can accommodate multiple milling heads for maximum process flexibility.
Applications
Frewitt equipment is used across a broad range of pharmaceutical applications:
- Size reduction of granulated and dried pharmaceutical powders
- Wet and dry milling for solid dose formulation development
- Delumping and deagglomeration of compressed or caked materials
- High-potency compound milling with full containment (OEB4–OEB5)
- Particle size classification and controlled size reduction
- Inline milling between process steps (post-drying, pre-blending)
Equipment Range
|
Conical Screen Mills Precision calibration mills for controlled particle size reduction. Available as FlexMill CW (premium) and EasyMill CM (production) in lab and production scales. Throughputs from 0.05 kg/h at lab scale to 5,000 kg/h in production. |
|
Oscillating Mills Gentle size reduction using patented oscillating and rotating sieve technology. Ideal for friable granules and shear-sensitive materials. FlexMill OW series from lab (up to 100 kg/h) through production (up to 2,000 kg/h). |
|
Hammer Mills High-energy impact mills for coarse to fine size reduction. FlexMill HW (premium) and EasyMill HM (production) series, lab through production scale. Throughputs up to 5,000 kg/h with the PowerMill MFH-15. |
|
Pin Mills High-speed pin mills for fine grinding and micronization down to 5 microns. FlexMill PMC series with two milling processes in a single system. Batch sizes from 100g to continuous production up to 1,000 kg/h. |
|
Crush & Delump Systems Inline crushers and delumpers for breaking up agglomerates, compressed blocks, and caked powders. Cone crushers and delumpers with throughputs up to 20,000 kg/h. Designed for installation between dryers, containers, and downstream equipment. |
|
Cryo Milling Cryogenic milling systems for temperature-sensitive, elastic, or waxy materials. Integrated cryo modules cool material to -100C, enabling brittle fracture of otherwise unmillable compounds. Available with pin mill and hammer mill heads. |
|
Rotary Sifters Inline sifting equipment for classification, safety screening, and deagglomeration of pharmaceutical powders. Integrates with Frewitt milling systems for closed-loop size reduction and screening workflows. |
