GENERAL ITEMS Answers to Questions Submitted

GENERAL ITEMS

Answers to questions submitted are as follows:

Q. Who is to supply the nitrogen supply system?

A. This will likely be ARGON and will be part of the facility (supply provided by customer).

Q. Who is to supply the containment of the classifier i.e glove box?.

A. There should be no container. The classifier should run with an internal inert (argon) atmosphere.

Q. The spec reads that the mill is required but then needs to operate as a pure classifier as Cuts are required to remove particles below 2μm and above 10μm which will require two passes through the classifier at 2 different classifier speeds.

We would need to trial the material to determine if we can achieve such a small particle range from D10 to D90 which is only 4.5μm but we do not have the facility to trial under nitrogen.

Would it be acceptable to present PSD (Particle Size Distribution) results from other materials run in the jet mill classifier?

A. This would be acceptable. Please specify if multiple passes would be required to meet the sizing in any proposal.
