Crushers . JAW CRUSHERS. Jaw crushers are primarily used for crushing minerals and rocks with a compressive strength that is not higher than 320MPa, such as limestone, sandstone, shale, gypsum, coal, and clay. The jaw crusher is used in a variety of industries, including mining, smelting, building material, highway, railway, hydraulic engineering, chemical engineering and more.

Compressive strength refers to the ability of a certain material or structural element to withstand loads that reduce the size of that material, or structural element, when applied. A force is applied to the top and bottom of a test sample, until the sample fractures or is deformed.. Materials such as concrete and rock are often evaluated using a compressive strength test and in these cases

Compressive Or Crushing Strength Compression across the grain is very closely related to hardness and transverse shear. There are two ways in which wood is subjected to stress of this kind, namely, (1) with the load acting over the entire area of the specimen , and (2) with a load concentrated over a portion of the area.

So, compressive strength is the highest load per unit area borne by the stone without giving in. A higher compressive strength between1,800 psi (12.45 MPa) and 19,000 psi (131 MPa) means the stone can endure an upper crushing load. Dry or wet conditions as per load determine the compressive strength of the stone. Bending strength test

Testing the compressive strength of the aggregate particles is not normally carried out to determine its strength or suitability. This property is normally determined by a simpler method such as the Aggregate Crushing Value (ACV) or the Los Angeles Abrasion test which also gives a measure of the abrasion resistance and "toughness" of the aggregate.
