Jaw crushers offer reduction ratios of up to about 61, while cone crushers can reduce material size up to a maximum of 81 ratio. The finer the crushing, the smaller the reduction ratio. As a basic rule, jaw crushers are the primary crusher taking the mined aggregate and reducing it to a size that a cone crusher can accept.

Jan 01, 2019 The coarse aggregates obtained by different crushing mechanisms jaw and impact crushers show very similar characteristics in terms of binder content assessed by acid leaching 27.5 and 26.6 wt., water absorption 8.76 and 9.75 wt. and porosity 18.6 and 20.2 vol..Thus, it is not possible to conclude that any of these mechanisms are more efficient in removing the cement paste
Oct 03, 2019 The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the ten percent fines value should be
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes 12.5mm, 10mm and 2.36mm Procedure to determine Aggregate Crushing Value i The aggregates passing through 12.5mm
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
