Information about the planetary ball mill and lead time, shipping way, warranty,etc

1. What is the smallest particle size the Planetary ball mill can mill down to?

The smallest particle size our mill can mill down to is 0.1µm. However, the final fineness varies greatly with different materials. The actual grinding result depends on mill speed, ball size, material, and grinding time. You will be able to find the best combination after a couple of tries.

 

2. How to choose the right jar material?

The general rule is the jar must be harder than the material being milled. Most times stainless steel is sufficient, if the material can react with metal, then agate is good. Otherwise, zirconia is common.

 

3. Is it necessary to use zirconia jars with zirconia beads?

It depends on why you are using zirconia beads as the grinding media. If the purpose is to avoid metal contamination, you should use zirconia, alumina, or agate jars. If the purpose is to use the hardness of zirconia to break up materials, stainless steel jars are fine. Although zirconia is much harder than stainless steel, these beads won't damage the jars.

 

4. How long will you deliver the goods after I place an order?

We will send the items within 7 days once your payment is completed. We do not guarantee delivery time on all international shipments due to differences in customs clearing times in individual countries, which may affect how quickly your products is inspected.


5. What's the warranty of the products?

For the ball mill machines, we offer you one year warranty. If any quality problems on our side occurred in this period, we will take on the shipping cost and replacement.

 

6. How can I choose a shipping method?

For small quantities, express of DHL/UPS/FedEx door to door service is the best; for bulk quantities, shipping by sea is the best but takes too much time. For urgent orders, we suggest shipping by Air to airport.
