First, when a stone (stone or Masato and other pieces of rock) is put into the hopper 11 and then moved to the lower vibration feeder 12, the soil powder 120 is separated through the grizzly of the vibration feeder 12, and then the soil powder 120 discharges to the conveyor belt 60h. Then, the stone is first shredded to a size of 100 mm or less in the jaw crusher 10 and transferred to the conveyor belt 60a to be put into the cone crusher 20 to crush second to 50 mm or less.

The stone crushed by the cone crusher 20 is transferred to the conveyor belt 60b and introduced into the upper first metal mesh 31 of the vibrating separator 30. At this time, the first metal mesh 31 is installed so that the stone passes only through 0-19mm, and the stone that does not pass through the first metal mesh 31 is transferred to the conveyor belt 60c and introduced into the impact crusher 40. . The stone passing through the first metal net 31 is introduced into the lower second metal net 32. At this time, the second metal mesh 32 is installed so as to pass only up to 0-4.75mm, and stones that do not pass through the second metal mesh 32 are transferred to the conveyor belt 60d and introduced into the jet crusher 50. . At the same time, the sand particles of 0-4.75mm passing through the second metal net 32 of the automatic sorting machine 30 are dust that can inhale dust and foreign matter (paper, vinyl) generated in the process of falling into the lower hopper as air. It is sucked through the suction chute (AIR INTAKE SHUITE) 70 and transferred to the cyclone (CYCLON) 90 through the corrugated pipe (81). The foreign matter 130 in the cyclone 90 is discharged downward by the specific gravity. The dust is collected by the dust collector (DUST COLLECTOR) (100) through a corrugated pipe 82 to collect in the dust pack 140.

As described above, the sand particles having passed through the second metal net 32 are transported by the lower conveyor belt 60e to remove the dust and foreign matter by the dust suction chute 70 by the lower conveyor belt 60e, and to the stock pile. It's being a beast.

The impact crusher 40 is again crushed into the stone less than 19mm by the conveyor belt 60f and the conveyor belt 60g again through the conveyor belt 60b and re-inserted into the vibrating separator 30 and repeatedly The crushed sand is transported to screen the crushed sand 110.

The jet crusher 50 breaks the injected stone back to 4.75 mm or less and transfers it to the conveyor belt 60g through the conveyor belt 60f and re-inserts it into the vibrator 30 through the conveyor belt 60b. And it will be able to screen the crushed sand 110 by vibrating separator (30).

The stone powder generated when the jaw crusher 10, the cone crusher 20, the impact crusher 40, and the jet crusher 50 are operated are dust suction suits 70 installed at the bottom of the equipment, respectively. Scattered dust and foreign matter sucked through is transferred to the cyclone 90 through the corrugated pipe 80, the foreign matter by the specific gravity is discharged to the lower side and the dust is dust-collected to the dust collector 100 through the corrugated pipe 82 To pack 140.

The present invention as described above can produce a large amount of crushed sand that can cope with the demand of the sand required in the construction site. In addition, by using stones (stone or masato and sculpted rock) to produce crushed sand, it does not use sand from the river or the sea, thus protecting the ecosystem and protecting the air and water environment.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but it will be apparent to those skilled in the art that various modifications are possible without departing from the scope of the present invention.

As described above, the present invention, unlike the conventional aggregate production method as a system configuration for producing high quality sand, can produce only a large amount of sand, and various stones, which are unnecessary fragments discharged from raw stones or Masato and other stone factories. It can produce sand by recycling the dust, and also it can process and produce high quality sand by preventing the scattering dust and removing foreign substances by using the suction power of the air (wind power) without using the wet or water washing method. It does not pollute the environment, and because it produces crushed sand using stones (stone or masato and sculpted rock), there is an indirect effect of protecting the ecosystem since it does not use sand of river or sea.
