From previous highways and railways to the construction of highways, high-speed railways, and elevated bridges, China's transportation and road construction industry is gradually moving towards a new level. The construction of the Shanghai Hangzhou high-speed railway and highways in various provinces and cities fully proves this point. As the most fundamental and widely used raw material for road and bridge construction, construction sand and stone materials have received widespread attention. How to choose a good crusher and sand and gravel production equipment is a top priority for many investors.

For the road construction industry, choosing equipment for crushers and sand and gravel production lines is a crucial issue, and the quality of the equipment is related to the quality of engineering construction. There are also significant differences in the quality requirements for sand and stone materials according to the level of construction of highways and railways. Improving the quality of sand and stone materials as much as possible is an inevitable choice for sand and stone factories, among which the selection of crushers, sand making machines, etc. is crucial.

The general production process of sand and stone materials is as follows: after blasting and crushing the mountain stones, they are preliminarily crushed by a jaw crusher. Then, according to the hardness and production needs of the stones, a reaction crusher or a cone crusher is selected for moderate crushing treatment. Finally, they are processed into standard sand and stone particles by a sand making machine. Wet sand making also requires a sand washing machine to clean the sand and stone materials, ultimately forming clean and high-quality construction sand and stone materials.

Of course, depending on the situation in different regions, some regions can directly use river pebbles or pebbles in the river for processing. The equipment that can be selected based on the sand content and particle size of the stones is: jaw crusher, cone crusher, sand making machine, etc. The entire equipment also includes a vibrating feeder, conveyor belt (belt conveyor), vibrating screen, and sand washing machine.
