How To Increase The Quality Of The Aggregates In The Crusher

Separation processes to improve the quality of recycled ...

2013-1-1  Abrasion resistance is an important property of aggregates and is often used as a general measure of the aggregate’s quality to resist being worn away or shattered through rubbing, friction and impact under loading or during handling, stockpiling and mixing. RCA are acknowledged to have on average lower abrasion and impact resistance (Los Angeles abrasion loss > 30%) than NA.

How to maximize the productivity of cone crushers (10

In order to maximize the productivity, the actual power of the cone crusher should be kept between 40%-100% of the rated power, and 75%-95% of the rated power during operation is the best choice. Operation beyond the rated power will affect the service life of the cone crusher and cause various problems.

Fig. 7 clearly shows that for a fixed value of sand-to-cement volume ratio, the inclusion of coarse aggregates caused an increase in both the rheological parameters (i.e., yield stress and plastic viscosity). For instance, when the sand-to-cement volume ratio is equal to 2.2, the yield stress moves from 251.59 Pa to 696.46 Pa by including ...

2014-1-8  increase in aggregate size results in a decrease in the compressive strength of concrete. Cook (1989) showed that, for compressive strengths in excess of 69 MPa (10,000 psi), smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used
