| 1. |
What type of material is suitable to process in the Powderizer mechanical impact type mills?
|
| |
Material should be:
Non-sticky
Somewhat friable
Mildly abrasive
No harder than 3 mohs
Feed material should not be hotter than 100dF. |
| 2. |
How much free silica can be in my material? |
| |
If Tungsten carbide internal impact and wear parts are used (optional abrasion resistive package), 3 to 5% silica may be tolerated. This option should incorporate a metal detector upstream to the mill to protect these Tungsten Carbide parts. If Tungsten Carbide is not selected for internal wear protection other type abrasion resistive parts can be offered. The silica limits on these are 0.2% for the Powderizer.
|
| 3. |
How fine can I mill my material? What are the top and bottom size constraints? |
| |
The Powderizer typically can mill down to a range of 50uM to 10uM dependant on the feed rate, the feed material size (PSD) and the friability of the material.
|
| 4. |
How much horsepower, KWH use is needed to process my material and for what capacity/feed rate?
|
| |
The Powderizer complete system can have a maximum of 525 installed hp for about 5 to 9 tph depending on material type.
|
| 5. |
Will the process heat up my material excessively?
|
| |
The Powderizer is an air swept type mill, therefore typically the exiting material in the exiting air stream will be 90 to 120d F, material dependant.
|
| 6. |
Can we blow through these type mills and what auxiliary equipment will I need, what will be included?
|
| |
No. The Powderizer is an air swept mill designed to work with negative pressure or a suction of product through the mill.
|
| 7. |
How often should I clean the mill? Are the internal parts easily accessed? |
| |
Depending on the material, cleaning the mill can range from once a month to never. Some models offer an optional water wash system. The internal parts can be accessed by removing only a few to a dozen bolts. Some models come with quick disconnect clamps and hinged clamp type designs.
|
| 8. |
Do you offer wash-down or stainless steel designs?
|
| |
Yes. We offer mild carbon steel design with either enamel or epoxy paint as an option and also have 304 and 316 Stainless Steel designs available.
|
| 9. |
How quick can we expect delivery? |
| |
Delivery under normal circumstances is 12 to 14 weeks after the design and drawings are agreed upon.
