Sep 12 2015 Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material W2 is expressed as percentage of the weight of the total sample W1 which is the aggregate crushing value. Aggregate crushing value W1W2100. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates. Also Read Crushing Test Procedure of Aggregate. Also read Crushing Value Test Procedure of Aggregates.
Dec 19 2019 The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement aggregate of higher crushing strength i.e. low crushing value should be

StonemontQC is designed for producers of crushed stone sand and gravel frac sand golf sand lime and cement and any other construction material that requires management of particle size analysis
Screening is another technique to control both quality and gradation of the aggregate product. PRODUCT QUALITY If deleterious material exists at undesi rable levels after crushing and may be identified as being predominantly in one size range that is not needed for product size the material may be screened out namely fines or top size.

Dear Ishwar kindly specify exactly the desired quality in order to get a specific answer. However and generally the crushed sand should follow the acceptance procedure of any fine aggregate type..
to test the aggregate before placing it on the road.Also if the tests fail you can work with the crushing contractor to try to blend and improve or reject the material. This becomes even more critical in producing material for pavement or base. Sampling Another issue critical to testing aggregate is

Apr 13 2021 The cone crusher adopts laminated crushing so the material is crushed by squeezing. It is suitable for crushing hard rocks such as granite basalt tuff river pebble etc. but the content of needle-like flake particles in the aggregate is high. Impact crushing adopts the principle of impact crushing.
Jaw crusher can be put at the first crushing sector primary crusher process the material 500mm. Impact crusher has a higher crushing ratio suits for the material which dont need repeatedly crushed. Cone crusher can produce a good shape particle. The gyratory crusher is used for shaping thus produce good quality gravel.
