Evaluation of blast fragmentation effects on jaw crusher
The findings of this paper prove that P 50, P 80, and P top sizes of a blasted rock size distribution have a direct effect on crusher throughput. The empirical relationship between crusher throughput and each fragmentation parameter is derived Introduction Aggregates or crushed rocks with different lithology (rock types) are used widely as construction materials [1], [2]. It is believed that aggregate shape characteristics have an important role in the behavior of aggregate materials e.g., [3], [4], The effect of rock crusher and rock type on the aggregate

The effect of rock crusher and rock type on the aggregate shape
The results indicate that the rock type has important effects on the aggregate texture and crusher type has significant effects on the aggregate form characteristics. The rock aggregates produced with JC are mainly blade and disc form, Obviously, increasing water content in the mixture will adversely affect the quality of concrete. Crushed rock dust acts as a filler and helps to reduce the total voids content in concrete. Consequently, this contributes to improve the quality of concrete.Effects of crushed stone dust on some properties of concrete

Advanced comminution modelling: Part 1 Crushers
Discrete element modelling of a rock cone crusher. Powder Technol. (2014) P.W. Cleary et al. Simulation of particle flows and breakage in crushers using DEM: Part 1 Compression crushers on the structure of slurry pools and mill discharge and on the adverse effect on grinding of increasing mill speed. Modeling and Improving the One possible source of construction aggregate is sand that has been manufactured from the surplus material (crusher dust) that results when coarse aggregate is produced in hard rock quarries. Coarse aggregate production typically yields 25% to 45% crusher dust depending on the parent rock, crushing equipment and crushing conditions . An Investigation into the Use of Manufactured Sand as a

How can metal mining impact the environment?
In some cases, bioavailable metals are absorbed by plants and animals, causing detrimental effects. Although current U.S. mining and reclamation practices guided by environmental regulations minimize or prevent waste rock erosion into streams, disposal of waste rock in places where it could erode into surface drainages has occurred Mining and quarrying for minor minerals impart significant economic, environmental and social impacts in and around the affected areas. The problem is severe in the small river catchments as the effective area available for assimilating negative impacts of the activity is minimal, compared to large river basins. To address these issues, an Environmental impact of quarrying of building stones and
