Now, in some rods the resin comprises only 25% of the material. Scott President Jim Bartschi says that the biggest "leap forward" in the new Centric fly rod series is due in large part to a new modified epoxy resin that adheres better, so there is less of it. The result is a lighter fly rod with greater carbon fiber density, and less ...

A model for rod milling is proposed which states that the top sizes present in the distribution are broken preferentially. For the small mill used in the tests the enhancement of specific rate of breakage is about, that is, when a particle is in the top 15% by weight it breaks times as fast as when it is in the bottom 85% by weight.

Stamp mills use a vertical crushing mechanism to break down ores, via a set of battery pads. The number of crushing pads varies between models, and those with more pads will generally come with a greater crushing capacity. Stamp mills are less sophisticated than ball mills, but affordable and effective for basic rock crushing.
