Whether it is to build railways, highways, or build buildings, or cast dams, a large number of sand and stone materials are indispensable. The main sources of sand and stone are natural sand (mountain sand, river sand, sea sand) and artificial sand (machine-made sand). Natural sand and stone materials have long been in short supply. In addition, in order to protect the ecological environment, after the regulations of prohibiting the excavation of river sand were issued, the sand and stone aggregate was in sharp shortage. The emergence of energy-saving sand making machines and sand production lines has brought hope to the sand industry.
VSI sand-making machine is a new type of energy-saving sand-making equipment developed and improved by SMMVIK Machinery after issuing the regulations prohibiting the mining of river sand. It is widely used in the infrastructure construction of roads, railways and other places. The use of the supporting sand and stone production line is even more powerful, providing a large number of sand and stone aggregates for various large-scale projects and improving the originally tense supply and demand of sand and stone.
The quality requirements of sand and gravel in construction projects are increasingly high, and it is also necessary to improve the quality of machine-made sand. High-performance sand and stone production line is adopted because of the high degree of automation of process configuration. The produced machine-made sand and stone has uniform grain size, good grain shape, and reasonable grading. It is an ideal sand and stone aggregate for highways, railways, high-rise buildings, municipal, hydropower dams, and concrete mixing stations. It is also the main source of sand for aerated concrete brick production.
As the core equipment for crushing in the machine-made sand production line, 5X impact sand-making machine plays an irreplaceable role in the machine-made sand production line and is the main source of artificial sand and stone. It is widely used in road construction due to its high crushing ratio and output, multiple use of one machine, and simplified process flow.
Gravel materials used in road engineering mainly include gravel and sand. Crushed stone is the orthopedic of various mud and concrete. Generally speaking, gravel with particle size of more than 2mm is called gravel, and sand with particle size of 2-0.074mm is called sand. Sand is the main raw material of cement mortar, cement lignite, asphalt concrete and asphalt sand. The sand-making machine has become a very popular dual-use equipment for sand and stone due to its adjustable discharge size. When making sand, the one-time finished product rate of less than 5mm accounts for more than 85% of the discharge, and its adjustable discharge range is 5-20mm. In addition to high production and energy saving, it is also a powerful equipment for producing 5-20mm stone.
