·The size reduction process of rocks in cone crushers is one of the most important issues particularly for the secondary and tertiary stages of crushing operations In this study 17 different rock types were considered for the evaluation of their size reduction variations that occurred in a laboratory scale cone crusher Based on several mineralogical physico
·The crushed aggregate is removed and sieved on a mm sieve The material passing through this sieve is collected and weighed The aggregate crushing value is obtained by the following expression Aggregate crushing value={W 1over W 2}times 100 Where W 2 = Total weight of the dry sample
·The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load It is expressed as the percentage by mass of the crushed or finer material obtained when the test sample is subjected to a specified load under standard conditions
·aggregate crushing value of coarse aggregate size is not available other sizes up to 25 mm may be tested but owing to the noIlchomo geneity of aggregates the results will not be comparable with those obtained in the standard shall consist of aggregate passing a mm IS Sieve and retained on a IO mm IS Sieve and shall be

·To prepare a sample for sieve analysis one must Obtain an aggregate sample; Mix the sample to ensure homogeneity; Reduce the sample to a testable size; Determine the total sample mass; Reducing the aggregate to an appropriate size for testing in sieve analyses is necessary to ensure that the sample can effectively pass through the sieves
·Remove the crushed aggregate from the cup and sieve using mm sieve The fraction passing the sieve is weighed M2 The fraction retained on the sieve is also weighed M3 If M2 M3 differs from M1 by more than 1 g discard

This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load The method is applicable to aggregates passing a 14 0 mm test sieve and retained on a 10 0 mm test sieve For other size fractions a recommended method is described in Annex A
·Aggregate crushing test values indicates the strength of aggregate and hence it is very significant Similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loads Sieve Size of mm 10 mm and mm; Aggregate crushing value test apparatus Aggregate crushing Test
·Also weigh the fraction retained in the sieve • Compute the aggregate impact value The mean of two observations rounded to nearest whole number is reported as the Aggregate Impact Value • Aggregate impact value = W2/W1 x 100 Where W1 is total weight of dry sample W2 is weight of portion passing through mm sieve
Sieve analysis of Aggregates of Dense Bituminous Macadam DBM Grading II Nominal maximum aggregate size mm Grain Size Analysis of Aggregates Particle Size Distribution Test Test for grain size analysis or sieve analysis of aggregates are done to determine its particle size distribution fineness modulus effective size and uniformity coefficient
Objective 1 Determine the aggregate crushing value of coarse aggregate 2 Assess suitability of coarse aggregates for use in different types of road Theory The " aggregate crushing value " give a relative measure of the resistance of
·The test results did not show a clear trend which might be attributed to the aggregate distribution and particle size However values in Table 4 were in the range of % of the cube compressive strength which is close to the range predicted by Eq 1 6 7 % Split tensile results calculated using Eq 2 were different from those of
The aggregate sample undergoes a specified load under standardized conditions producing a percentage mass of fines which is then calculated as a ratio of the weight of fines passing through specified sieves to the total weight of the sample to determine the crushing value of the aggregate The lower the crushing value the stronger the aggregate
·determining the percentage of the material crushed finer than a specified size Definition The aggregate crushing value ACV of an aggregate is the mass of material expressed as a percentage of the test sample which is crushed finer than a 2 36 mm sieve when a sample of aggregate passing the 13 2 mm and retained on the 9 50 mm sieve is
