Applications & Case Studies
- Specialty Coatings
- A large company supplying specialty coatings for government aeronautical applications needed to have their (Epoxy Resin) granular powder reduced to 95% < 25 or better. The raw material was in the form of 1/16" to 1/2" chunks from their supplier and was pre-crushed at their facility then sent to us for jet milling. We were also asked to perform the pre-crushing prior to jet milling, which we were able to do. However, we took it one step further and fed their raw material in chunk form into our jet mill without pre-crushing and found that our mill could make specification without the pre-crushing, thus saving the customer the costs for the pre-crushing step. Finished product size results were 9.16 avg, 95% < 17.94, and 100% < 27.38, which far exceeded their best expectations.
- Unusually Fine Alumina
- Various grades of alumina are regularly processed with particle size results ranging from 1.5 Avg to 3.5 Avg and top sizes ranging from 5 to 20 . One of our customers needed a special grade that required a much finer specification that the standard jet mill would have trouble reaching economically. Our Engineering Department took on the challenge, resulting in a new design improvement that consistently and economically produced particle sizes of 1.1 - 1.3 Avg with a top size of < 4.
- Moisture Sensitive Materials
- Moisture sensitive materials obviously require dry air during the jet milling process which is easily accomplished with the use of an in-line dryer system. One product was particularly sensitive after jet milling with dry air and sitting for long periods of time. It was determined that the addition of a flow agent would extend the shelf life of the product without affecting product quality. This was accomplished by co-feeding the flow agent with the product at a specified percentage during the jet milling process, thus producing an evenly blended homogeneous material that eliminated the agglomeration problem with minimal additional cost.
- Processing Precious Metals
- Minimizing losses during production is particularly important when processing precious metals and other valuable materials. While jet milling is inherently very efficient in minimizing losses, the control of setup, processing, packaging, and clean up, is an integral part of the milling system. Additional procedures were developed for various customers to even more extensively control and minimize losses to the degree that typical losses were reduced to 0.5 to 1%.
