The optimal dimensions are about that of a basketball. There is also a crusher that crushes typically the rock into smaller measurements and feeds the killed material into another appliance called a rock screener. The job of the screener is to dimensions the stone into hemroids of different sizes. There are typically three sizes of gemstone produced.

There are a number of factors which influence the mashing process. Some of the factors affecting crushing ratio are firmness, material resistance strength, measurement, shape, density and wetness. There are some external factors also such as the interaction and syndication of materials when crushing is conducted.
In mashing, the external force needs to be great to overcome the particular binding force between the rock particles. The structure regarding crystals in the rock determines how strong the combination is in the rock.
There are 3 stages.
(1) Splintering period: where energy absorption develops and the rock is depressed in a few large pieces.
(2) Crushing stage, where huge pieces are further killed
(3) Compaction stage, where sheet pieces are damaged. This stage produces small chucks.
Rocks are killed on construction sites including quarries. Rocks are completely crushed on demolition and also recycling sites. Excavated boulders on jobsites that may usually be regarded as a waste materials product can be turned into benefit with crushing. Crushed natural stone can later be used in concrete, in the construction connected with roads, as fill material in building foundations, for erosion control, as entrée, to bed piping regarding underground utilities, in paved foundations under pavers, and landscaping.

If your product is used onsite, another highlight is no need to haul off the unwanted. It is also a more environmentally friendly to use onsite product.
There are several diverse machines which crush rocks. Some of the crushers include jaw line crushers, cone crushers, impact crushers and roller crushers.
