The shaft portion 23 is provided so that the upper and lower portions thereof penetrate the upper and lower plates 21 and 22 and the lid 16 and the bottom portion of the case 10, respectively.

The hammer 24 is fixed to the upper and lower plates 21 and 22 through a hammer portion of a circular rod and a fixing rod 24a extending in the hammer portion at a smaller cross sectional area than the hammer portion and arranged in the vertical direction. . The hammer portion may be configured with one or more grooves (e.g., a shape in which both sides of the longitudinal direction communicate with the outside) on the head portion.

The hammer 24 is installed between the upper and lower plates 21 and 22 through one fixing rod 24a while being stacked along the longitudinal direction and the fixing rod 24a is disposed between the upper and lower plates 21 and 22, The upper and lower portions of the hammers 24 are fixed to the upper and lower plates 21 and 22 with a nut or the like. The hammer 24 is crushed by crushing the crushed material while rotating around the fixed rods 24a.

The roll type mill 25 is a cylindrical drum having a plurality of protrusions arranged in a vertical direction and having a plurality of protrusions formed along the circumferential direction on the circumference thereof.

The hammer 24 and the roll mill 25 are separated from each other by a transverse partition, and the partition is sized so as not to interfere with the pulverization of the pulverized material.

The hammer 24 and the roll type mill 25 may be installed in alignment with the edges of the upper and lower plates 21 and 22 and may be installed to protrude beyond the edges of the upper and lower plates 21 and 22.

When the hammer 24 and the roll mill 25 are arranged in a multi-stage, the hammer 24 and the roll-like mill 25 are disposed at the lower portion and have a large cross-sectional area, thereby efficiently crushing the pulverized material concentrated at the bottom portion.

The upper and lower plates 21 and 22 include a hammer means fixing portion for fixing the fixing rods 24a and 25a so that even when the hammer 24 and the roll type mill 25 are worn, And has two or more hammer means fixing portions to reduce the cost loss.

The hammer means fixing portion is in the form of a hole through which the upper and lower portions of the fixing rods 24a and 25a respectively pass, that is, two or more fixing holes 24-1 and 24-2 through which the fixing rods 24a and 25a pass, (25-1, 25-2).

The first fixing holes 24-1 and 25-1 and the second fixing holes 24-2 and 25-2 are provided at different distances with respect to the shaft portion 23 as the first fixing holes 24-1 and 25 -1 is closer to the shaft portion 23 than the second fixing holes 24-2 and 25-2.

Therefore, the hammer 24 and the roll type mill 25 are fixed to the first fixing holes 24-1 and 25-1 (fixed rods 24a and 25a are fixed) The fixing rods 24a and 25a are separated from the first fixing holes 24-1 and 25-1 and fixed to the second fixing holes 24-2 and 25-2 so that the hammer 24 And the roll type mill 25 are moved to the striking and milling positions of the pulverized material and used.

The hammer means is not limited to the combination of the hammer 24 and the roll type mill 25, and the hammer 24 and the roll type mill 25 may be used alone.

The drive means 26 is composed of a motor 26a and a power transmission means (belt or the like) 26b for connecting the rotational force of the motor 26a to the shaft portion 23. As shown in the figure, The drive shaft is disposed toward the bottom portion and the power transmission means 26b is installed to be wound on a drive shaft of the motor 26a and a pulley coupled to the shaft portion 23. [

As shown in FIG. 2 and FIG. 5, the particle size adjusting unit 30 adjusts the particle size of the coarse aggregate and the fine aggregate and the ratio of the coarse aggregate and the fine aggregate through the gap between the granulator 20 and the discharge port 12, A space adjusting plate 31 whose one side is rotatably connected to the case 10 and whose angle is adjusted through the space adjusting driving means, a separating plate 31 removably mounted on the inner surface of the space adjusting plate 31, And a particle size adjusting liner 32 for controlling the squeezing and rubbing degree of coarse aggregate on the opposite side.

The particle size control liner 32 is also formed in a concave-convex shape like the liner 14 of the case 10 described above and is assembled and detachably attached to the interval adjusting plate 31 through a fastener.

As the distance between the particle size adjusting liner 32 and the vertical mill 20 is changed according to the angle change of the particle size adjusting liner 32, coarse aggregates having various particle sizes are obtained.

The gap adjusting driving means is connected to a power transmission member such as an angle adjusting motor 33, an angle adjusting motor 33 and a belt 34 so as to rotate in one direction or both directions and is connected to the gap adjusting plate 31, And an eccentric shaft 35 that adjusts the distance between the vertical grinder 20 and the vertical grinder 20.

In addition, a supporting means may be applied for the restoring force of the angle regulating plate 31 and the size control liner 32.

The support means includes a support rod 36 which is installed around the angle regulating plate 31 in a forward and backward direction along the angle adjusting direction of the angle regulating plate 31 through a guide means and has one side rotatably connected to the angle regulating plate 31, And a coil spring 37 as an elastic member for elastically supporting the support bar 36 in one direction.

The angle adjusting motor 33 can be driven temporarily by the operation of the manager or continuously driven during the production of coarse aggregate, and is controlled so as to match the distribution of particle sizes of the recycled aggregate.

The method of manufacturing the vertical dry coarse aggregate and fine aggregate according to the present invention is as follows.

1. Feeding pulverized material.

And a pulverized material (for example, a particle size of 40 mm) is introduced into the inlet 11.

2. Grinding.

When the driving means 26 of the vertical pulverizer 20 is operated, the vertical pulverizer 20 rotates clockwise with reference to Fig.

The pulverized material charged into the case 10 through the charging port 11 according to the positions of the charging port 11 and the discharging port 12 and the rotating direction of the vertical pulverizer 20 moves one wheel, ).

The liner 13 of the case 10 opposite to the vertical crusher 20 supports the crushed material and the hammer 24 of the vertical crusher 20 strikes the crushed material and crushes the crushed material into a small particle size And the roll type mill 25 is crushed into small pieces.

Since the hammer 24 and the roll type mill 25 are alternately disposed along the circumferential direction, the hammer 24 is crushed to a small size by hitting the crushed material, and the physical properties of the surface are weakened, The crushed material is controlled to be scraped and the ratio of coarse aggregate to fine aggregate is adjusted.

Since the interval between the vane 14 and the vertical mill 20 becomes narrower as the hammer 24 and the roll mill 25 approach the discharge port 12 and the discharge port 12 is closer to the discharge port 12, The pulverized material is concentrated and the grinding efficiency is improved.

In addition, since the linear envelope 14 is arranged in a hexagonal shape and the vertical grinder 20 is circular, a space is widened at a portion where the envelope 14 is connected. Therefore, the case 10 has a narrow space It is possible to maximize the crushing efficiency because the crushed material is crushed in a narrow space and then moved to a wide space and mixed.

3. Emissions.

The coarse aggregate (for example, 10 mm to 20 mm) and the fine aggregate (for example, 10 mm or less) are discharged to the outside of the case 10 through the discharge port 12 and the size of the coarse aggregate To produce coarse aggregates of various sizes.

At this time, a fine powder (0.02 mm or less) which can not be recognized as a fine aggregate (sand) is included. The present invention is configured as follows to select a fraction of 0.02 mm or less for quality certification as sand.

The composition for the selection of the differential is as follows.

As shown in FIGS. 6 to 8, the suction device 200 and the suction device 200 connected to the vertical dry coarse aggregate and the fine aggregate manufacturing device 100 of the present invention, And a cyclone 300 for sorting the inhaled differential.

The suction means (200) and the cyclone (300) are fine powder removing means.

The suction means 200 connects the suction pipe 210 to the upper portion of the case 10 and the blowing pipe 220 to the cyclone 300.

A net (a grating is also possible) through which the aggregate can not enter the hole of the case 10 to which the suction pipe 210 is connected but the fine particle passes can be applied.

Here, a differential scattering wing is configured to efficiently select the differential in the case 10.

The differential scattering wing is formed on one side of the upper portion of the upper plate 21 and the lower portion of the lower plate 22 so that the upper side differential scattering wing 27 and the lower side differential scattering wing 28 can be configured have.

The upper side differential scattering fins 27 are formed on the upper surface of the upper plate 21 so as to have a curved shape with a plurality of axes centering on the shaft portions and the lower side differential scattering fins 28 are formed on the bottom surface of the lower plate 22, (In the same direction as the upper side differential scattering blade 27).

The upper side differential scattering blade 27 and the lower side differential scattering blade 28 increase the sorting efficiency by scattering the fine powder and prevent the crushed material from accumulating between the upper and lower plates 21 and 22 and the case 10, It also protects the system.

According to this configuration, the coarse aggregate and the fine particles (mixed state of the fine aggregate and the fine powder) are present in the case 10 through the vertical dry coarse aggregate and the fine aggregate manufacturing apparatus 100. At this time, (27) and (28) to the suction pipe (210), and the fine powder is sucked without interfering with the aggregate.

The fine particles sucked by the suction means 200 pass through the blowing pipe 220 and then flow into the cyclone 300 and are collected.

Through the above process, coarse aggregate and fine aggregate from which fine particles have been removed are produced. In the subsequent process, fine aggregate and fine aggregate are screened by screen to finally produce fine aggregate (sand).
