What's The Difference Between Crushing And Pressing Grapes ...

Crushing is what's done before the fermentation. It's what changes the plump grapes from something you pop into your mouth to something you can slop around in a fermenter. Crushing the grapes is a very straight-forward task. It's simply a matter of bursting the skins so that all the inner solids can be exposed to the fermentation.

Cone Crusher - an overview | ScienceDirect Topics

These crushers are designed so that the head-to-depth ratio is larger than the standard gyratory crusher and the cone angles are much flatter and the slope of the mantle and the concaves are parallel to each other. The flatter cone angles help to retain the particles longer between the crushing surfaces and therefore produce much finer particles.
