Productive process of Symons cone crusher:
The cone moves in the prejudiced returning along the inside surface of the fixed cone. At the part of the moved cone closes to the fixed cone, the materials among this part become crushing cavity after being pressed, knocked and bended by the moved cone. At the place where the moved cone deviates from the fixed cone, the crushed materials get out from the cone bottom under the gravity.
