The jaws of the jaw crusher
Here are the jaws of the jaw crusher Crocodile. Some improvements have been made to bring the smooth rocks down the jaws to be “eaten”. We may need or not these improvements, yet we are going to handle tens of tonnes of rocks by using this crusher.
These jaws are made out of manganese.
Manganese, Mn, atomic number 25 – a hard brittle grey polyvalent metallic element that resembles iron but is not magnetic; used in making steel; occurs in many minerals.
