aggregate crushing value can be determined by using a simple formula: this test is repeated once or twice and the average crushing value of the aggregate is determined. the average crushing value in the different tests is the actual crushing value of aggregate. important points to remember.
acv 100 2500 20.4 result: aggregate crushing value 20.4% result analysis: the value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality.
the aggregate crushing value test set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod. all parts of the apparatus are powder coated or galvanized steel, heat treated and ground

gyratory and cone crushers have advantages such as relatively low energy consumption, a reasonable amount of control over the particle size of the material and production of low amounts of fine particles
both gyratory crusher and jaw crusher can be used as coarse crushing machinery. compared with the two, the advantages of gyratory crusher are: the crushing process is carried out continuously along the circular crushing chamber, so the production capacity is large, the unit power consumption is low, the work is stable, suitable for crushing sheet materials, and the particle size of crushing products is more uniform.
advantages of gyratory crusher: big depth of the crushing chamber, continuous work, high production capacity and low unit electricity consumption. stable working condition, light vibration and small basic weight. generally speaking, the
when compared with jaw crusher, gyratory crusher has the following advantages: deep crushing cavity, continuous operation, high production capacity, low unit power consumption. It has the same It has relatively stable working state, less vibration and less weight of the equipment
