Mechanical Crushing Of Rocks

•Bed of rock gives smoother operation. •The rocks are gradually crushed as they are transported through the crushing chamber. •The entire chamber is utilized for crushing. •The rocks falls slides through the chamber until they are crushed directly between the concave and mantle. •The rocks are crushed in one strike which yields big forces.
