What Is Silicon Carbide? We then have silicon carbide, which is also referred to as carborundum. This is a very hard chemical compound that contains mainly silicon and carbon. In nature, it occurs naturally as a rare mineral known as moissanite, but is generally mass produced as a crystal or powder, and has been since the late 1800s.

The BM2200+ Planetary Nano Ball Mill operates with two grinding bowls in the sizes 20 ml, 45 ml or 80 ml, which turn with a transmission ratio of 1 : –2 relative to the Sun Wheel. The grinding Jar is arranged on the sun wheel of the Planetary Nano Ball Mill off centred.
2. What is the capacity of milling we want? The Planetary Mill PULVERISETTE 5 premium line provides two stations of grinding bowls with 500 ml volume (largest capacity on the market). Each grinding bowl can be filled 1/3 part of the volume (± 170 gr sample). So, if we use two grinding bowls, the optimum capacity is about 170 x 2 = 340 g per milling process.

IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).
