Diamond reserves and production of South Africa are in the front rank of the world. Large-scale development and utilization of diamonds result in production of a large number of diamond wastes. Resource utilization of diamond waste can turn waste into tre

The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Crushing value is a measure of the strength of the aggregate The aggregates should therefore have minimum crushing value 3 APPARATUS

Jan 04 2014 · Test Name Methods for determination of Aggregate Crushing Value ACV Code BS 812 Part 110 IS 2386 Definition of ACV Aggregate Crushing Value ACV gives an relative measure how the aggregate act under an gradually acting compressive load Sieve Size ACV is applicable for aggregates passing 140 mm sieve and retained on 1000 mm sieve For other size fractions methods

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 236 mm sieve when a sample of aggregate passing the 132 mm and retained on the 950 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN

The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of 13295mm aggregate so that 10 per cent of the total test sample will pass a 2 36 mm sieve

The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads Impact Value The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact The impact value of an aggregate is sometime used as an alternative to its crushing value

aggregate crushing value of coarse aggregate NOTE 1 The ‘aggregate crushing value’ gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load With aggre gate of ‘aggregate crushing value’ 30 or

The tests for Aggregate Crushing Value ACV and FACT 10 Fines Aggregate Crushing Test measure the crushing strength of broken rock These results do not necessarily relate to the flexural or compressive strength of concrete made with that aggregate but are a useful index of overall quality Normal values for ACV range from 14 to 30 and for

Optimization of a Final Crushing Stage This method applies to other crushers where a control variable is available The crushers are the last size reduction stage in the value chain Over crushing is common The connection between crusher setting and yield is often unknown The rock cannot be repaired We need to control the crusher
