Cushion. The material remaining in the barrel, in front of the screw, after the mold filling and pack stages of the injection process is called the cushion. Having a cushion ensures that the screw does not bottom out against the front of the barrel, thereby preventing control of packing. Cushion is critical for most parts to assure they can be ...

There are two wellknown modes in which the ball charge moves inside the mill: cascading and cataracting. The cascading motion of ball charge forms a compressive zone inside the mill where particles may break under slow compression. The cataracting motion, on the other hand, causes the particles to break under highimpact forces.

4 Enhances Color. The facets of the cushion cut are great at retaining color which means that it's an excellent cut for colored diamonds and gemstones. The cut's larger facets emphasise the color of the stone. While this is excellent for colored gemstones, it's bad news for colorless diamonds (more on this in the cons section).

As you increase the volume of the through put, the time that the ore has to react to the grinding media is lessened. As you add ore to the mill you are also adding WATER and changing density which affects the slurry rheology and workings of the grinding action inside that mill. This water is one of the main controls that you have over your grind.
