DESIGN AND ANALYSIS OF A HORIZONTAL SHAFT IMPACT
Impact crushers involve the use of impact rather than pressure to crush materials. Here the material is held within a cage, with openings of the desired size at the bottom, end or at sides to allow crushed material to escape through them. This type of crusher is generally used with soft materials like coal, seeds or soft metallic ores.

Cone Crusher an overview ScienceDirect Topics
Cone crushers were originally designed and developed by Symons around 1920 and therefore are often described as Symons cone crushers. As the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory crushers.
