  • The importance of crushing in aggregate processing

    As to the crushing methods, there are two most common types: compression crushers and impact crushers. Compression crushers adopt the theory of squeezing or pressing between rigid surfaces, such as jaw crusher, cone crusher, dual-roller crusher, etc., while impact crushers employ impact, such as impact crusher, vertical shaft impact crusher, super-fineness energy-saving crusher, etc.

    The gravel is then sprinkled with water and enters the tertiary crusher (secondary impact crusher); which is the last crusher used in the chain.After this the crushed stone is conveyed to a separator having three decks.(32mm, 12mm, and 5mm top to bottom) The aggregates greater than 32mm will be taken on the top sieve and cycle back to secondary

  • Aggregate Crushing Value Test Determine Aggregate

    Concept and significance of the Aggregate crushing value test. The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under
