Frewitt develops and manufactures milling systems used in the milling, crushing and sieving of powders and bulk solids in the defence industry.

The company also provides expertise in powder transfer, de-agglomeration, dosing and filling solutions, in addition to high-tech particle classification and homogenisation.

Milling solutions for R&D and analytical laboratories in the defence sector

Frewitt has created a wide range of lab mills for research and development (R&D) and analytical laboratories in multiple industries, including pharmaceutical, fine chemical, food, and defence.

Frewitt produces milling systems for food processing powders and granulates.
Our multilingual service engineers are on-hand to take care of client questions.
Efficient customer service is our primary focus throughout all industries.

This development enables the company to provide an innovative machine platform, supporting six different milling processes.

The FlexMill-Lab features a revolutionary design, accommodating six diverse, milling processes in a single system, enabling users to produce a range of particle sizes, including a lower particle size distribution spectrum of D90 < 10μm.

FlexMill-Lab offers unequalled, process scale-up enhancement, enabling for batches of 50g to 1kg for small-scale, laboratory applications, while ensuring the flexibility of a 30 kg/hr to 50 kg/hr light production rate for pilot-scale quantities.

Crucially, FlexMill-Lab guarantees true scale-up from lab size batches to pilot-scale and to high-volume industrial production levels.

The sixth and newest milling process, the FlexMill-NW, is a high-performance bead mill on our FlexMill-Lab platform, which allows wet nano-milling down to 50nm, providing customers with an additional dimension to particle size reduction.

The global system enables users to alternate between diverse milling processes swiftly and efficiently. Detachable heads can be removed and replaced with other heads within seconds, sealed for cleaning and sanitising.

Powder sizer reduction technologies

To supply a wide range of production solutions for use within the numerous industries, while providing perfect scalability with our labs’ machines, Frewitt have a production scale line of machinery.

As an industry leader in powder size reduction technologies, we offer FlexMill-Prod, a innovative solution that unites multiple milling processes in one milling system, designed and scaled for industrial production levels.

These units enhanced by a factor of 5: FlexMill Prod proves its capabilities with the same degree of flexibility across the entire range of your processing needs, from small batch to large-scale production.

FlexMill-Prod also enables the implementation of milling platforms to suit current and future production requirements.

Turnkey solutions for military organisations

At Frewitt, we recognise a growing requirement for ‘turnkey’ solutions. We have developed several modules that are perfectly adapted to our machines. The modules permit the end-user to improve the usage of the machines in terms of dosing, cleaning, conditioning, gas management, N2 Inerting, and O2 monitoring.

Engineering and testing services

As well as being a renowned machine manufacturer, Frewitt offers a number of additional services to its clients, including engineering and testing services.

We also offer an after-sales service and analyses in our laboratory, as well as on-site process audit, process development, machine upgrades, logistical support, and leasing.
