High-containment system with an integrated mill
Frewitt
This company’s new containment system with an integrated mill (photo) is mounted on a mobile base consisting of an isolator, a continuous liner system (CLS) and a Fredrive-Lab mill. The Fredrive-Lab is mounted on a lifting column, forming the core of the system. Using this flexible mill, heat-sensitive, hard, crystalline and fibrous products can be pulverized, de-agglomerated, calibrated and milled (D90 to 10 µm). Depending on the milling process and the material to be processed, the operator can choose between six different milling heads, which are easily interchangeable on a single flange. The milling heads can be introduced and taken out using a CLS mounted on the side and on the bottom of the isolator. This is also used for changing the individual screens and rotors, as well as for feeding the products to be processed. A frequency-regulated fan permanently controls the negative pressure in the isolator. Hall 3.1, Stand D27 — Frewitt AG, Granges-Paccot, Switzerland
