Is Custom Processing
Right For You?
|
| |
| What services do you offer? |
 |
|
|
Jet milling, inert milling, hammer milling, blending, and cryogenic grinding. |
| |
| What size mills do you offer at your facility? |
|
|
|
Jet mills are available in sizes from 2", 4", and 8" for laboratory work, and 12", 15", 20" and 24" for production milling. In addition, crushing, hammer milling, and blending equipment are all available in
full production scale. |
| |
| What types of materials do you process? |
|
|
|
Abrasives, pigments, cosmetics, heat and moisture sensitive materials, food additives and non-sterile cGMP materials. We have handled a large number of dry materials in our 30+ years of custom grinding. Test and Production quantities can range from grams to truckload campaigns. |
| |
| What types of materials
don't you process? |
|
|
|
Known carcinogens, extremely hazardous materials and environmental toxins (PBT’s).
We require an MSDS of all materials for our pre-evaluation, prior to processing.
|
| |
| Are there any limitations on the size of the feed materials? |
|
|
|
For our laboratory size jet mills, we prefer 30 mesh or less and 8 mesh or less for production sizes. The feed
stock can be pre-crushed at our facility; however, our production crushing equipment can work with material as large as 6 inches in diameter. |
| |
| What particle size can you grind to? |
|
|
|
The majority of our jet milling is to less than 10µ with the averages ranging from 1µ to 5µ. Sizes down to 0.5µ average is achievable on many products and coarser sizes are simply a case of adjusting operating parameters. High speed crushing equipment can produce material as fine as 200 mesh but typical sizes are 120 mesh by down. |
| |
| How is particle size measured? |
|
|
|
Horiba LA-950, Coulter Laser, Coulter Multisizer, microscope, screen (sieve)analysis, Fisher Sub Sieve Sizer, and grind gages. |
| |
| How
do you keep my material contamination free? |
|
|
|
The first step is to run a clean facility with the absence of airborne contamination, which is prevalent in many other grinding operations. The second step is to thoroughly clean the equipment and inspect it before starting a job. Our jet mills are ceramic lined where the product contacts the milling surfaces. There is no direct impingement on milling surfaces but the encapsulation of the grinding action with ceramic eliminates contamination or discoloration. For softer materials, stainless and resilient liners are available. |
| |
| What
can I expect the losses to be? |
|
|
|
Losses on production work are usually well under 1%. Everything
is collected in a dust bag or bag house dust collector. The initial
coating on the pulverizing equipment and collection device accounts
for the majority of any loss. |
| |
| How much does this service cost? |
|
|
|
Small jobs are billed on a hourly/daily basis. Larger production is priced on a per pound basis. Packaging and freight charges is additional. |
| |
| What sets Jet Pulverizer apart? |
|
|
|
Scrupulous supervision, clean facilities, and a work force that has
not experienced any turnover in over 15 years. We promise a 100%
effort on every job and work ethic that does not compromise on
quality. |
