The type and output of aggregate are determined by the capacity of the crushing and screening machine, the maximum capacity can be 1000t/h. if want a higher output, only by increasing the crushing production line. take a three crushing aggregate processing plant as an example.
The average crushing value in the different tests is the actual crushing value of aggregate. Important points to re. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for
Calculation of Aggregate Crushing Value. The ratio of weight of fines formed to the weight of total sample in each test shall be expressed as a percentage, the result being recorded to the first decimal place. Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve

The aggregate process consists by progressive stages of crushing, screening, and washing. Aggregate production line manufactured by aims for producing crushed stone aggregate. Crushed stone aggregate is produced from many natural deposits including: limestone, granite, trap rock and other durable mineral resources.
“Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load” In situations, when aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined and used instead.
Concept and significance of the Aggregate crushing value test. The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under
The cone crusher (a compression type) simply crushes the aggregate between the oscillating cone and the crusher wa ll (Figure 5-9). Clearance settings on this equipment are required to be checked and maintained as part of standard operating procedure. Figure 5-9. Cone Crusher

Facebook; Twitter; and making sure all guards and safety devs are in place, secured and functional before operating the crusher. It is important to ensure that operators review and follow all lock out, tag out and try out (LOTOTO
Significant degradation may take place when the aggregate is weak. Thus, an aggregate complying with a specification at the production site may fail to do so when it is in the pavement. The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load.
Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surface-dry sample
Apr 08, 2017· The aggregate crushing value provides a subjective measure of the resistance of the aggregate crushing in the pressure of the progressively smeared compressive load. When the aggregate crushing value is 30 or greater the outcome can be irregular and in those kind of circumstances the ten percent fines value has to be assessed in its place.
construction, is the ability of the aggregate to resist crushing. The Aggregate Crushing Value gives a relative measure of the resistance of the aggregate to crushing under a gradually applied compressive load. 220.127.116.11 Scope. The particular purpose which an aggregate is meant to serve requires the aggregate to have a particular strength.
Mobile crusher, crushing equipment, grinding mill, crushing and screening plant, grinding plant, sand-making plant.There is a leading place for us in global mining machinery because of high efficiency, low costs, and good environmental effect.
This implies that different practs may be taking place in one agency, depending on what pavement application that aggregate source is used for. 3.2.1 Quality Tests Conducted on Virgin Aggregates Chapter 2 introduced the major tests used to check the quality of virgin, recycled, artificial, and byproduct aggregate materials used in various

Jan 07, 2019· How Concrete Is Recycled . Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate.
May 08, 2013· 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) × 100 Record. The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material.
The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength. After sieving aggregates, a cylindrical measure is taken and find the empty weight of cylindrical measure(We).It is then filled with aggregates in three layers with 25 blows to each layer using a tamping rod.
