It is hard and heavy, so many raw materials are pulverized. After putting 4 pieces in a 1.5 L ball mill container and turning at a rotation speed of 180 rpm, the container was broken into 4 pieces. Since there is no choice, the container is glued, and a gum tape is rolled and used.

Since one piece weighs 250 g, we were able to crush the raw material in a short time. I think load fluctuation to the rotating table and wear of the ball mill container are great. By the way, we are pulverizing peppers and marbles now.

I tried purchasing it experimentally I think that it is easy to use because it is a quantitatively exact quantity as it is used in the test

We are satisfied with using as water resistant and corrosion resistant parts. Accuracy is also reasonable.

Unfortunately I thought that it was an activated alumina ball I purchased it by mistake and I could not achieve my purpose. I thought that I would like to ask you to deal in the future if it was what I wanted.

I think that the quality is good but the price is a little cheaper. I purchased 1 mm, but the actual measurement was a mix of 1.16 to 1.26 mm. Since there is an error of 10% or more, I think whether it is better to add a hand to the notation.
