By definition, basalt is an aphanitic (fine-grained) igneous rock with generally 45-53% silica (SiO 2) [] and less than 10% feldspathoid by volume, and where at least 65% of the rock is feldspar in the form of plagioclase. This is as per definition of the International Union of Geological Sciences (IUGS) classification scheme.

The application depending on whether you are working in quarrying, mining or recycling, determines the most suitable jaw plates - and ultimately the right crushing chamber. M1 is the standard alloy, offering high resistance to shock and impact. It also work hardens well with hard rock. Our M8 and M9 alloys offer higher resistance to abrasive ...

The cross-sectional area is a geometric property of structural elements such as beams, columns, slabs, etc. and it is used to calculate the axial stresses in Cross-sections. In general it can be said that the greater the dimensions of a cross-section under a given load, the greater the Cross-sectional area and the smaller the axial stress.
