Elongated And Flaky Particles In Aggregate

Generally, hard and brittle rocks are easy to produce elongated and flaky particles when they are broken. Crusher based on attrition crushing produce high content of elongated and flaky particles, and without inner crack, such as jaw crusher, cone crusher. Crusher based on assault crushing produce low content of elongated and flaky particles, such as sand making machine.

Study on Elongated And Flaky Particles

The influence of aggregate, which distinguish from the maximum dimension, the aggregate grading, different content of needle or plate to sand rate under different B and W/ B, has been investigated. The results show that there are optimum max. grain size, size distribution and acicular content as well as optimum sand percentage for coarse aggregate used for high strength and high performance concrete under the test conditions of this study. A maximum 4% of needle and plate particle content is certified.

How To Improve Elongated And Flaky Particles On Aggregate Crushing Plant

stable and continuous feeding of the crusher
Stable and continuous feeding will make the crusher full of feed, ensure the mutual extrusion between material and material in the crushing chamber, and make flat and long strip particles fractured along its thin section.
Adjust the ratio of the best discharge opening for coarse, medium and fine crushed
chieve a balanced production to reduce the content of needle-like crushed stone.
Reasonable crushing and screening process
If the stone is coarsely crushed or crushed by a crusher, it will be directly discharged to the finished product screen. Material smaller than the mesh size will directly become the final product, increasing the proportion of the needle-like content, and reasonably crushing. The screening process is also a way to reduce the content of crushed stone tablets.
