Metamorphic rock
Metamorphic rock - Pressure, Heat, Transformation: The pressure experienced by a rock during metamorphism is due primarily to the weight of the overlying rocks (i.e., lithostatic pressure) and is generally reported in units of bars or kilobars. The standard scientific notation for pressure is expressed in pascals or megapascals (1 pascal is equivalent to …

Selecting the right crusher for your operations
Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...
