Nowadays, with the economic development, requirement on infrastructure project has also increased. At present, many hydropower construction converted all concrete roller compact into concrete dam in thehydropower construction, and the RCC months pouring intensity reached around 200,000 m. Sand and gravel aggregate in roller compacted concrete has a requirement on stone powder content. Part sand and gravel aggregate commonly produced by artificial sand production can’t meet stone powder content sometimes, so, when it failed to meet the requirements of stone powder content, you can increase or decrease a raymond mill production line to deliver the stone powder content.
The quartz sand production line has features of high degree automation, low operation cost, big crushing rate, energy saving, high yield, less pollution, simple maintenance, mechanism sand conform to the national standard of building sand, uniform particle size, good granule shape and reasonable distribution and so on.
After modification construction of hydropower station for the dam concrete, through the corresponding transformation for sand system has been made, but the whole process has not changed, so choose Raymond mill powder production line in roller compacted concrete sand in the production of sand stone powder content is the helpless choice when it can’t reach the requirements. In order to ensure the powder content and stability of finished products sand stone, after the analysis and comparison, we should introduce raymond grinding powder production line. After adding stone grind in raymond grinding powder production line, sand stone powder content can meet the design requirements.
