The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. 2.Apparatus Required Fig. 1: Balance Balance should be accurate upto 1 gm. Fig. 2: Sieve
(e.g. Crusher gap setting) in the mineral processing of aggregate products ( in this case granite from MountSorrel Quarry). 1.2 UK Aggregate Industry The aggregate industry is worth £3 billion per annum to the UK economy (Lafarge Aggregates 2006). This study will centre on granite production at MountSorrel Quarry owned by Lafarge/Tarmac.
The aggregate crushing value is defin ed as a ratio of the weight, of fines passing the specified sieve (2.36 mm) to the total weight of the sample expressed as a percentage.

mechanical processing such as crushing, washing, and sizing. • Some natural aggregate deposits, called pit -run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. • Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Figure 1. Natural aggregates & gravels : 4.1.1.2 Crushed rock aggregates • Crushed
crushing plant, it is imperative to optimize these structural and construction costs to suit the life of the operation. Perhaps a steel-supported, modular design will be best for short-term operations, since the equipment can be relocated and re-used; while for long-life mines, large concrete structures with fully insulated enclosures might be more economical. In conducting trade-off studies

Impact crushers usually will benefit the aggregate better than compression crushers, and they may generate more fines. Common types are the horizontal shaft (Figure 5-12), vertical shaft, and hammermill impactors. Figure 5-12. Horizontal Shaft Impactor The horizontal shaft single or double roto r may aggressively handle large and odd-shaped material. Large horizontal impactors sometimes are

crushing and screening in an aggregate plant. The production of crushed aggregate may include quarrying (drilling and blasting) from solid rock, or may start with selected secondary material from mines, building rubble or the metallurgical industry, etc. The sourced material is reduced into smaller particles by a primary crusher (, Symons). This material is moved onto an intermediary
Report the mean as the Aggregate Crushing Value, unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the Aggregate Crushing Value. A data sheet is given as Form 7.7.1. 7.7.2 10% Fines Value Test 7.7.2.1 Scope. The
