Two-stage stochastic programming with recourse is a natural modeling framework for applications in which a here-and-now decision needs to be made, followed by the realization of random param-eters. For such two-stage models, the recourse action consists of additional decisions to be made after observing the random parameters.

Shear and compression forces occur as the feed material is pulled between the crushing plate and/or crushing rolls. Depending on the feed size, material is fed into the crushing chamber and encounters a single or a pair of rotating rolls. If a two-stage reduction is required, either a Triple or Quad Roll configuration can be used.
