The gravel production line is a production line equipment for producing sand and stone for construction. The products produced include stone and artificial sand, so it is also called a gravel production line. It is equivalent to the combination of a stone production line and a sand production line. The gravel production line equipment can meet the needs of producing stone and artificial sand together. It not only has a high degree of automation, low operating cost, and high crushing efficiency, but also energy saving, high output value, and less pollution. The machine-made sand produced meets the standard requirements for construction sand, and the production particle size is uniform and the configuration is reasonable. In the process flow of the gravel production line, due to the reasonable configuration of crushing equipment at all levels and the spatial cross-planning, it occupies a small area, has a reasonable and economical investment, and is equipped with electronic control operation, making it easy to operate and efficient and energy-saving.

How to judge the performance of the sand and gravel production line? There are two indicators for judging product performance: "the ratio of needle-like particles" and "powder content". If the needle-like particles of sand and gravel exceed the specified specifications, it is considered unqualified. Now the construction material specifications for high-speed railways, highways, etc. are very strict. A reasonable production line can effectively prevent the increase of needle-like fragments. What are the equipment to prevent the increase of needle-like particles? Jaw crusher, impact crusher, cone crusher, etc. The country also has requirements for powder content. If the powder content is too much, it is also considered unqualified sand and gravel and cannot be used in engineering construction.

Many large stone factories are specialized in supplying stone materials for high-speed rail construction, highway construction, etc. If the output value cannot meet the needs of engineering construction after the production line is put into operation, such a production line is considered an unqualified production line, which is very harmful. Therefore, when choosing a production line, users must open their eyes, watch, listen and compare more, and choose a production line that meets the requirements. For our beautiful tomorrow, we must configure reasonable and standardized production equipment.
