3. Fine crushing The crushed stone from the coarse crushing equipment is transported through the belt conveyor to the fine crushing machines for secondary crushing. The secondary crushing equipment mainly includes an impact crusher and a cone crusher, which are responsible for the middle and fine crushing in the stone crushing process.

taken from the conveyor that feeds the screen. Silt content of the stone as sampled (wet) was negligible, and the average silt content of the sample after drying was 3.35 percent. The relatively small amount of silt particles (<75 µm) present in the raw material suggests that the potential for PM-10 emissions from the
Silt Content in Sand As Per IS 383:2016, uncrushed sand (natural sand) can have a maximum silt content of 3% by weight, while crushed sand (manufactured sand) can go up to 15% by weight. Figuring out how much silt is …

Percentage of Silt Content = (V1/V2) x 100. V1 - Volume of silt layer V2 - Volume of sand layer. For example, for a given sand sample, if V1 comes out to be 9 and V2 is 130, the % silt content would be 6.9 %. The permissible value of silt …
The presence of excess quantity (> 8%) of silt in sand reduces the bonding capacity of raw materials and affects the strength and durability of work. It is recommended to conduct silt content test for every 20m 3 of sand.
The fine aggregate could be natural sand or crushed stone sand. The aggregate retained on a 75-micron sieve and passing through a 4.75 mm sieve is called sand. The coarser sand that has 4.75mm and 2.36mm particles is generally …
of silt content to fine aggregate exceeds 5%. The compressive strength, however, when silt fine content is small than 5%, increases only 1 MPa. But decreases from 3 MPa to 5 MPa when the silt content increases from 7% to 9%. These results could serve as a reference in concrete production as well as quality control of fine aggregate

A combination of 3/8 Crushed stone and washed sand. It is a replacement for river sand in a concrete building. Crushed Sand possesses balancing physical and chemical properties that can withstand harsh climatic conditions.
Silt particles are smaller than sand particles but larger than clay particles. High silt content in sand can lead to numerous issues, including reduced strength, high compressibility, and low permeability. Test for Silt Content in Sand: Silt content test is a simple test to that helps determine the percentage of silt present in the sand sample.
