Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to Tensile strength which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength

Crusher is to make bigger stone (30mm~1000mm) smaller (0mm~50mm); popular crushers have jaw crusher, impact crusher, VSI crusher (sand making machine) and so forth. Crusher can work separately or together with other equipments (like vibrating feeder, belt conveyor,vibrating screen etc.) to form a stone processing plant, the designed capacity
natural-shaped stone. It also means that the material resists movement under loads better and gives better strength or stability.This will vary throughout the country, but bank run gravels are nearly always improved through the crushing process. Quarry gravels are considered very good material since they are com-posed of virtually all fractured
