By the system of the present invention configured as described above will be described in sequence the manufacturing process of the sand using the Masato stone.

First, when the raw material Masato is injected into the hopper 110 of the grinder 100, only the gemstones having a predetermined size (5 cm) or less are filtered by the screen 111 and are introduced into the hopper 110. As such, the Masato stored in the hopper 110 starts to be crushed by colliding with the crushing rods 127 of the pulverizing drums 125 and 126 rotated at high speed by a starting motor (not shown). As the crushed masato is moved from the upper mill 100 to the lower side, the crushed particles become smaller to obtain predetermined crushed particles having a size of sand particles. At this time, Masato is completely destroyed by the cracks such as quartz, silica, feldspar and mica. The crushed particles not crushed to below a certain size are separated and removed on the screen 112 at the bottom of the crusher 100.

The crushed particles pulverized in this way are guided through the chute 113 and introduced into the separator 214 of the separator 200, and the crushed particles introduced into the separator 214 are rotated by the motor 219. As the rising vortex is generated by the rising vortex fan 222 of the sand, the crushed particles of the sand size do not rise to the bottom of the separation vortex 214 and the light particles which are not suitable for the fine particles and sand are separated by the rising vortex. It floats above the water surface of the top of 214.

The fine particles floated on the water surface of the separator 214 is guided by the plate-shaped fixing fan 225 together with water to the sludge treatment plant 130 through the chute 211 and the screen chute 129 of the separator 214. Particles that are transported and then trapped and larger than these particulates continue to be transported along the screen chute 129 to be trapped in the mass processing plant 131.

The crushed particles settled to the lower part of the separator 214 of the separator 200 are more rapidly generated by the torsion fan 223 and the cone-shaped screw 224 under the rotating shaft 216 and into the chute 215 of the lower part. Push out. In this way, the crushed particles guided by the chute 215 are introduced into the inner surface of the polishing drum 310 of the polishing machine 300, and thus the crushed particles introduced into the inner circumferential surface of the polishing drum 310 are rotated as the polishing drum 310 rotates. It is transferred upward along the screw 313 of the inner circumferential surface.

As such, the sharp edges of the crushed particles are polished in a continuous process of dropping and collecting by the triangular pyramidal protrusion 315 and the collection piece 316 formed between the screws 313. The first abrasive particles thus polished are continuously transported upward along the cylindrical screen 314, which is a rising separator connected to the top of the polishing drum 310, and then stored in the lower hopper 401.

When the water passes through the cylindrical screen 314, water is sprayed in the sprayer 327, so that the particles attached to the abrasive particles are washed, and particles smaller than the particle size of the screen are drawn out of the bottom of the screen 314, so Separate with abrasive particles. The abrasive grinder 300 grinds the crushed particles, and the cylindrical screen 314, which is an upward separator connected to the abrasive grinder 300, separates and sorts by the size of the abrasive grains. In the cylindrical screen 314, sludge which is not separated in the separator 200, which is a second stage, is separated. Particles and small particles exiting the cylindrical screen 314 are collected in the supporting container 329, and the mass processing plant 131 is disposed. Transported to

As described above, the abrasive particles primarily polished and separated by the rising abrasive 300 and the cylindrical screen 314 are again ground by the vibratory polishing machine 400 to be 80% compared with the crushed particles crushed in the grinder 100. The above grinding process is performed.

Referring to the process of grinding by the vibratory polishing machine 400, the eccentric shaft 414 installed inside the hollow rotating shaft 418 is rotated at a high speed by a separate high speed motor (not shown) hollow rotating shaft 418 Vibration is imparted and rotates at a low speed by a low-speed motor (not shown) in a state in which the air tire-type roller 402 continuously attached to the outer side of the hollow rotating shaft 418 in this state is elastically contacted. have.

In this state, when the abrasive particles are introduced from the hopper 401 between the air tire type rollers 402, the abrasive particles are polished again due to the action of the air tire type rollers 402 rubbing the abrasive particles. As such, when the pair of rollers 402 contacted with each other are rotated in the same direction and rotated with a slight difference in rotational speed, or rotated in different directions, the abrasive particles can be more effectively polished.

As such, the secondary abrasive grains are guided through the chute 409 and introduced into the separator 214 of the separator 200, and thus the abrasive particles introduced into the separator 214 have the same operation in the second step. The detailed description is omitted. At this time, the sludge and mica generated in this process due to the rising vortex generated by the rising vortex fan 222 of the rotating shaft 216 are floated on the upper surface of the separating container 214, and the fine fine yarn is separated. The chute at the top and the screen chute 129 outside the tank 210 are carried along.

The abrasive particles settled below the separator 214 of the separator 200 are vortexed by the torsion fan 223 and the cone-shaped screw 224 under the rotating shaft 216 and further into the chute 215 below. Push out quickly. As such, the abrasive particles guided by the chute 215 are generated by the rising vortex fan 222 of the rotating shaft 216 rotated by the motor 219, so that the inner surface of the polishing drum 310 of the lifting polisher 300 is raised. The abrasive particles introduced into the inner circumferential surface of the polishing drum 310 are transferred upward along the screw 313 of the inner circumferential surface as the polishing drum 310 is rotated.

As described above, the edges of the abrasive grains are polished again in a continuous process of dropping and collecting by the triangular pyramidal protrusion 315 and the collection piece 316 formed between the screws 313. The secondary abrasively polished particles are stored in the hopper 501 installed under the upper side of the polishing drum 310.

As described above, the abrasive grains stored in the hopper 501 at the upper end of the polishing machine 300 are introduced into the orbital polishing machine 500 to be polished once again. Referring to the above polishing process, a plurality of support plates 510 elastically installed on the bottom of the endless track 502 and the roller 505 of the air tire type for each of the endless tracks 502 of the support plates 510 include a motor 509a. Is linked with low speed.

In this state, when the abrasive particles are loaded on the crawler 502, the abrasive particles are pressed and rubbed between the upper surface of the crawler 502 and the roller 505 to polish the abrasive particles by friction.

The abrasive grains passing through the caterpillar 502 of the orbital polishing machine 500 are washed once again as they flow along the uneven chute 132 along with the water sprayed from the hopper 501 of the orbital polishing machine 500. And smooth grinding of the abrasive particles.

As such, the abrasive grains polished along the uneven chute 132 are again introduced into the separator 214 of the separator 200, and the abrasive particles introduced into the separator 214 are rotated by the motor 219. Rising vortex is generated by the rising vortex fan 222. At this time, the sand-sized abrasive particles win the rising vortex and do not sink to the lower portion of the separation vessel 214, and the light particles that are not suitable for the fine particles and sand float on the surface of the upper portion of the separation vessel 214 by the rising vortex.

The fine particles and lightweight particles floated on the water surface of the separator 214 are guided by the plate-shaped fixing fan 225 together with the water and discharged through the chute 211 so that the fine particles and the light particles are separated. While passing through the screen chute 129, the mass and sludge is screened again.

The abrasive particles settled to the lower part of the separator 214 of the separator 200 are more rapidly moved to the chute 215 of the lower part by vortexing by the torsion fan 223 and the cone screw 224 below the rotating shaft 216. Push out. In this way, the abrasive particles guided by the chute 215 is introduced into the inner surface of the polishing drum 310 of the polishing machine 300, and thus the crushed particles introduced into the inner circumferential surface of the polishing drum 310 are rotated as the polishing drum 310 is rotated. It is transferred upward along the screw 313 of the inner circumferential surface.

In this way, the abrasive grains are polished by a continuous process of dropping and collecting by the triangular pyramidal protrusion 315 and the collection piece 316 formed between the screws 313 while being moved upwards, so that they fall from the polishing drum 310 and are stored in sand. It is accumulated at 133.

Listing the uses that are generated in all the stages of the present invention, the sludge is used as a mixture of internal / exterior bricks with silica sand, quartz and feldspar residue composed of clay, sesa is used as sand for industrial paper, Plastering is used as a finishing sand for building, sand is produced in the highest amount, and is widely used in all fields such as ready-mixed concrete and separate poison.

As described in detail above, according to the sand manufacturing system using the masato of the present invention, the crack state of the crushed particles can be completely eliminated by crushing, grinding and separating the raw masato into the size of sand particles. In addition, by grinding the sharp edges of the crushed particles made of quartz and silica sand, which are the main components of the sand particles, there is a unique effect of producing sand particles having a good and even particle size distribution in a round state such as natural sand.

In addition, the present invention is to crush the masato while sprinkling enough water over the full width of the crusher can be shredded to the size of the sand particles without dust as an environmental pollution source and to wash the foreign matter attached to the crushed particles by the water to obtain relatively clean crushed particles There is a distinctive effect.
