Pulverizer Mills

Pilot mill series

Small batches of product (3g to 100kg) and all demands of laboratory needs can be grinded by the PilotMill series.

The PilotMill series provides maximum flexibility of use and complete scalability of the industrial process: it is the result of an optimization study that minimizes components and provides for connections between them in accordance with cGMPs so as to ensure fast and easy assembly, disassembly and cleaning.

All the Pilot Mills are available with volumetric or gravimetric feeder, cloth bag separation filter, manual control panel and data recorder compliant to CFR21 Part11.

PilotMill series can be easily integrated into FPS isolators to enable the processing of very active or sterile products. It is also available in an ATEX configuration. Special configurations, such as with PTFE or ceramic inserts and/or coatings, Hastelloy, etc., can be requested.

At FPS MEC Test Centre it is possible to perform technical trials with your products and FPS jet mills.

The FPS

PilotMill-2

The PilotMill-2 jet mill is designed for small batches of product from 1g to 3kg. Depending on this process condition, PilotMill-2 provides higher micronized product yield. It is available in a top discharge configuration with product recovery inside the filter bag to further maximize product yield.

The PILOTMILL-2 is the result of an unparalleled optimization study that involved the milling chamber, the nozzles and the classifier.

PilotMill-3

The PilotMill-3 jet mill is suitable for R&D activities and the micronization of product batches starting from 3g and up to about 10kg, ensuring extremely low product loss.

PilotMill-4

The PILOTMILL-4 jet mill is designed for product development’s needs, where batches from 5g to 60kg are considered. It is available in top and bottom discharge configurations.
