| 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 with out 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%. |
