Sand Production Line
Sand production line is generally divided into dry process and wet process sand sand two production processes, equipment and working principle of these two different production processes required .
Late in the legal process of dry sand wet sand the legal process , the legal system is based on the traditional wet sand production line further launch . Legal wet sand production line mainly mining machinery equipment vibrating feeder, belt conveyor , crusher , VSI crusher , vibrating screen , sand washing machine.
Dry process production line of sand mining machinery and equipment vibrating feeder , belt conveyor, sand making machine, vibrating screen , crusher, high efficiency sand powder separator machine.
Dry sand have legal advantages :
1, the dry process is more environmentally friendly energy sand , eliminating water waste ;
2, dry sand to remove the legal content of mud powder sand , building sand to reach the standard ;
3 , at the same time removing mud powder , leaving the right amount of powder on the work of improving the low intensity level of concrete have more help , almost no effect on the strength of concrete .
But note that, when high dust content , have an adverse impact on the preparation of high strength concrete strength. As can be seen from the technical requirements , the general did not sand production line system of the modulus, dust content for effective adjustment control technology, it is difficult to make a stable quality and meet the requirements of the gravel .
However, with respect to a wet sand, dry sand more legal advantages:
1, dry sand to get rid of the legal environmental constraints , are not affected by water and the environment. Water scarcity in place , but also the implementation of dry artificial sand . The traditional method of wet sand needs to be carried out in water-rich regions, and in the northern winter as too cold to produce .
2 , compared with the traditional method of wet sand , dry sand legal system more cost savings. First, water resources , saving a huge amount invested .
3 , dry sand section Another advantage lies in the legal environment, can not only save water , is still some way to save the mineral resources, the rational utilization of the production process powder .
In the stone processing, stone dust is generated due to the impact so that ,
in the production of artificial sand will inevitably contain a certain amount of powder and clay powder. The presence of mud powder sand will seriously affect the distribution, but rather the presence of powder can make up the gap caused by the artificial sand in concrete big , big water demand , poor liquidity shortcomings . Sand washing machine played a key role in addressing this problem through the sieve sand washing machine to wash gravel , mud powder volume greatly reduced , so that the artificial sand building sand to reach the standard .
The following is an advantage of the wet artificial sand :
1 , produced by a wet sand aggregate, sand the surface clean, perception and texture are better ;
2, using plenty of water , no dust production environment will not cause air pollution.
