The sand and gravel production line is a combination of stone production line and sand production line, which can simultaneously produce sand and stones. The complete set of equipment for the sand and gravel production line is a combination of various equipment specialized in producing construction sand and stones. It can make various rocks, ores, limestone, basalt, granite, pebbles, river pebbles, etc. into various sizes of construction sand and stones, with uniform particle size and regular shape, High compressive strength, far more in line with building requirements than natural sand and stone, and can better improve building quality.

For hard rocks with high hardness and abrasivity index, choose "jaw crusher+cone crusher+shaping machine (i.e. vertical shaft crusher)". The reason for choosing shaping machine is because the cone crusher has a high content of needle like aggregate after crushing, which does not comply with the standard GB/T 14685-2001;

For limestone, with moderate hardness and abrasion index, choose "jaw crusher+impact crusher" or "impact crusher+impact crusher".

It should be noted that hammer crushers are rarely used in the production of sand and gravel aggregates. Although the hammer crusher is a one-stage crushing process with a simple process, due to the low yield of large aggregates after hammering, easy crushing, and a large amount of powdery materials, the finished aggregates will produce microcracks and reduce compressive strength, which affects the quality of aggregates and sales.
