Artificial sand, gravel and other aggregates have become the mainstream way of engineering construction at home and abroad. Many people who want to enter this industry are very concerned about the investment in sand and gravel plants, how much money is needed to build a gravel plant? What procedures are required? How to select the crusher equipment?
According to the different grades of road and railway construction, there are also great differences in the quality requirements of sand and stone. It is the inevitable choice of sand and stone factory to improve the quality of sand and stone as far as possible, among which the selection of gravel crusher, sand making machine and other sand and stone production equipment is very important.
The general production process of sand and stone material is: After blasting and crushing, the rock is preliminarily broken by the jaw crusher, and then according to the needs of stone hardness and output, the impact crusher or cone crusher is selected for medium crushing treatment, and finally, the sand and stone particles are processed into standard sand and stone particles by the sand making machine. The wet sand making machine is also required to be equipped with a sand washing machine for cleaning and processing the sand and stone, and finally the clean and high-quality building sand and stone are formed.
Of course, according to different situations, some areas can directly use the river pebbles. According to the sand content and particle size of the stone, the optional equipment is: jaw crusher, cone crusher, and sand making machine, etc. According to the actual material situation, the complete set of equipment also includes vibrating feeder, conveyor belt (belt machine), vibrating screen and sand washing machine. Generally, crusher production companies will carry out product collocation according to the actual situation of customers to achieve the working efficiency of crusher equipment. At the same time, choose a good gravel machine equipment enterprise can also save a lot of maintenance time, which provides a stable operation premise for the profit and income of sand and stone factory.
