Hematite ore is an important mineral resource. With 70% iron content and the large iron output capacity, hematite is the most important iron ore. To improve the comprehensive usage efficiency of hematite, hematite beneficiation process is necessary. We ne
Gypsum powder plant is a kind of micronized line which turns natural dihydrate gypsum ore (raw gypsum) or industrial by-product gypsum (desulphurization gypsum, phosphogypsum, etc.) into construction gypsum (calcined gypsum) through crushing, grinding, he
Gravity separation is the main beneficiation method of chrome ore, and the equipment is jigger, shaking table, spiral classifier, centrifugal concentrator and spiral chute, etc. Sometimes it will also use weak magnetic separation or strong magnetic separa
Gold ore whose types of deposits are diverse and complex is the mineral assemblage of gold. With features of chalcophile affinity and high melting point, the gold ore includes conglomerate type, porphyry type, quartz vein type and volcanic rock type, etc.
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions
For determination of the aggregate crushing value of coarse aggregate which passes 125 mm IS sieve and retained on 10 mm IS sieve Calculation The ratio of the weight of fines formed to the total sample weight in each test is to be expressed as a percentage to the first decimal place Aggregate crushing Value W B W A
For example Weight of aggregate retained on length gauge of 10 mm to 63mmW2 150 gm and Total weight of aggregate sample 1000 gm Elongation Index 150 gm 1000 gm x 100 15 Result Percentage of flaky aggregate in the range of 10 mm to 63 mm is 15 IRC recommended the Flakiness Index Value
Using 200 mm sieves 8” is possible to test up to 1000 g of aggregates and 3000 g with 300 mm 12” dia The sieves specifications are clearly marked on the label comprising the serial number and other information for the identification and traceability of the product as
Then crushed aggregates are then sieved through 236 mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates

compressive load With aggregate of aggregate impact value AIV higher than 30 the result may be anomalous Also aggregate sizes larger than 14 mm are not appropriate to the aggregate impact test The standard aggregate impact test shall be made on aggregate passing a 14 mm BS test sieve and retained on a 100 mm BS test sieve
