The ridge 4A 'of the last row of the holding blades 4 (discharge port side) is formed higher than the other three rows of ridges 4A.
The raw material processing space between the 'and the inner peripheral surface of the rotary drum 1 is smaller than the raw material processing space of the other ridges 4A. This holding blade 4
Have peaks 4A, 4A 'and valleys 4B, 4B' formed alternately in the circumferential direction of the rotor 2. Yamabe 4A '
Is provided at a position located at the final stage side of the treatment of crushed stones, that is, at the discharge port side. The peak 4A is shorter than the peak 4A ', and is provided in three rows from the raw material inlet 6 side. Also, the peaks 4A, 4A in the axial direction of the rotor 2
Is divided by a plurality of valleys 4C, 4C '. The valleys 4C and 4C 'are formed so as to gradually narrow toward the bottom. Also,
The walls 10 of the valleys 4C and 4C 'are, as described later,
The rotor 2 is formed so as to gradually narrow the interval in the rotation direction. That is, it is formed so that the entrance in the direction in which crushed stones and the like are sent is wide and the exit is narrow. FIG.
In FIG. Since the ridge 4A 'is taller than the ridge 4A, the raw material input from the inlet 6 is forcibly consolidated by the step between the ridge 4A' and the ridge 4A, so that a product of even higher quality is obtained. Can be produced.

FIG. 2 is a longitudinal sectional view of the holding blade 4 provided with the low crest 4A in FIG. 1, showing the mutual positional relationship between the rotating drum 1 and the rotor 2 and the relationship between the scraping blade 3 and the holding blade 4. This shows the mutual positional relationship.

FIG. 3 shows a holding blade 4 having a low peak 4A.
1 shows a perspective view of one unit. The top surface 4D of the crest 4A is formed as a smooth surface, and a gentle slope wall 4E is formed from the top surface of the crest 4A at the front position toward the valley 4B with respect to the rotation direction. Toward the top surface 4D of the peak 4A, the valley 4B
A straight wall 4F is formed along a line that intersects the surface at a right angle. The valley portion 4B is partitioned by a rib 40 formed at a height up to the valley 4C in the axial direction.

FIG. 4 is a sectional view taken along line AA of FIG. 3, and a mounting hole 41 for mounting the holding blade 4 to the rotor 2 is provided in the valley 4B.

FIG. 5 is a front view of one unit of the holding blade 4, and FIG. 6 is a rear view thereof. From both of these drawings,
The shape of the valley 4C formed between the peaks 4A provided at predetermined intervals along the axial direction becomes apparent. That is, the valley 4C has a tapered shape in which both walls 10 gradually become narrower toward the bottom portion 11. Further, as described above, both walls 10 are formed in a tapered shape in which the distance between them gradually decreases in the rotation direction (see FIG. 5).
That is, in FIG. 5, the valleys 4 </ b> C have tapered shapes not only in the vertical direction but also in the direction that penetrates the paper from the front of the drawing. As shown in FIG. 3, the holding blade 4 is a single unit, and has two rows of peaks 4A, four peaks 4A in one row, and peaks 4A in the other row.
Are three, and one valley 4C is closed by the other crest 4A in the circumferential direction. This is because when the rotor 2 rotates, the raw material A such as crushed stone that has passed after being sandwiched between the valleys 4C at the front in the rotation direction collides with the straight wall 4F of the other crest 4A, and the raw material A This is in order to be able to apply sufficient pressure.

FIG. 7 shows a perspective view of the holding blade 4 provided with the high peak 4A '. In the holding blade 4, the ridges 4A 'and the valleys 4C' adjacent to each other in the circumferential direction are present on the same circumference. That is, unlike the holding blades 4 having the low peaks 4A, the peaks 4A and the valleys 4C are not alternately arranged on the same circumference.

FIG. 8 is a cross section taken along a valley 4C 'adjacent in the circumferential direction in FIG.
As in the case of the holding blade 4 provided with the
′, A straight wall 4F ′, and a rib 40 ′ and a mounting hole 41 ′.

FIG. 9 shows a plan view of the holding blade 4 having the tall ridge 4A '. The valley 4C 'of the holding blade 4 is also gradually narrowed in the direction of rotation, and the bottom 11
Is formed in a tapered shape so as to become narrower even toward.

FIG. 10 shows a state in which the raw material A is held in the valley 4C of the holding blade 4. FIG. 11 is an enlarged view of a state where a raw material A such as crushed stone is held in the valley 4C. This FIG.
4C, a large pressure acts on the raw material A, and the raw material A can be efficiently crushed and polished. That is, since the valley 4C has such a shape that the distance between the valley 4C is gradually narrowed toward the bottom 11 and also narrows in the rotation direction, the raw material A that enters the valley 4C.
8 is the location of the bottom 11 and the exit side of the valley 4C, that is, FIG.
At a location X and Y in (consolidation effect).

FIG. 12 is a perspective view showing one unit of the scraping blade 3. In the scraping blade 3, ridges 31 and valleys 32 are alternately formed in the direction of the inner peripheral surface of the rotary drum 1, and a small valley 33 is formed on the top surface of the ridge 31.
Partition walls 34 having substantially the same height as the ridges 31 are provided along the inner peripheral surface at predetermined intervals in the axial direction of the scraping blades 3. The one unit of the scraping blade 3 has a valley 32 formed between two rows of ridges 31, and two partition walls 34 are provided so as to partition the valley 32. By providing such a partition wall 34, the raw material A such as crushed stone can be transferred to the valley 3
2 is prevented from moving from the input side to the discharge side more quickly than necessary, and is temporarily stored in the space of the valley 32 surrounded by the partition wall 34 and the peak 31, and crushed stones are formed at the stagnation point. The raw materials A such as are sufficiently collided with each other so that polishing and crushing are surely performed. In FIG. 12, reference numeral 35 denotes a mounting hole. A large number of the scraping blades 3 of one unit are mounted on the inner peripheral surface of the rotary drum 1 through the mounting holes 35. At this time, the peaks 31 and the valleys 32 of the plural units are arranged on the same straight line in the axial direction.

The scraping blade 3 has a steeply inclined wall 31A of the hill portion 31 on the rotation direction side of the valley portion 32 and a moderately inclined wall 31B on the opposite side. The number of the partition walls 34 may be one in one unit, or may be three or more.

FIG. 13 shows an example of the arrangement of the scraping blades 3. In the input side, the direction of inclination of the peak 31 and the valley 32 with respect to the axis is the direction in which the raw material A is sent from the input port 6 side to the discharge port side. (With a feed angle). The outlet side has an opposite slope, ie, a stop or return angle. The inclination angle of the peak 31 of the scraping blade 3 on the discharge port side may be parallel to the axis.

By using such a scraping blade 3, the raw material A such as crushed stone can be scraped up to an optimum upper portion at the valley portion 32, and the valley is formed by the gentle inclination of the wall 31B opposite to the rotation direction. Smooth metabolism of the raw material A in the section 32 can be achieved. Also, instead of grinding and crushing the raw material A at the peak portion 31, the raw material A such as crushed stone between the surface of the raw material A held at the valley portion 32 and the small valley portion 33 and the rotor 2 side is polished and crushed. Therefore, abrasion of the top surface of the peak portion 31 is significantly reduced, and it can withstand long-term use. Further, by forming the small valleys 33 and the valleys 32, the pressure applied to the raw material A increases at the small valleys 33 and decreases at the valleys 32. Thus, the raw material A such as crushed stone can be sufficiently polished and crushed by changing the compressive force.

FIG. 14 shows the pressure action exerted on the raw material A by an arrow, which is sufficiently crushed and polished, and in particular, the retaining blade 4 having the last tall peak 4A 'and the partition wall 34. Is carefully treated at the place where the scraping blade 3 is provided.

In the embodiment shown in FIG. 1, the case where the holding blades 4 in the fourth row are also short (peak portions 4A) (Example 1) and the embodiment shown in FIG. 1 (Example 2) Table 1 below shows the results of comparison of the processing capacities of the above.

[0022]

[Table 1]

FIG. 15 shows an embodiment in which the holding blades 4 are arranged in six rows, and the crests 4A of the center two rows of holding blades 4 are shown.
Are parallel to the axis (that is, there is no angle), from which the two rows of holding blades 4 on the inlet 6 side have a feed angle, and the two rows of holding blades 4 on the outlet side have a stop angle. In addition, the holding blades 4 on the discharge port side are adjacent to each other in the circumferential direction.
A and the valley 4C are on the same circumference.

FIGS. 16 to 18 show the means for driving the rotation of the rotor 2. That is, the rotation shaft 5 of the rotor 2 is connected to the output shaft 21 by the universal joint 20, and the output of the motor M is transmitted to the output shaft 21 via the reduction gear 22. V pulley 23 of motor M and V of reducer 22
A V-belt 25 is stretched between the pulley 24. Compared with the method of rotating the rotor 2 by the chain method, when the universal joint 20 is used, the loss in the transmission of the rotational force of the motor M is greatly reduced, and the direct drive method is used. 132KW for chain type motor and 90KW for this type motor.
Further, since the universal joint 20 is always free in the vertical direction, when the raw material is clogged inside the machine, it can escape upward, so that the universal joint 20 absorbs the impact on the rotor 2 and the shaft. The rotor 2 can be protected. When the position of the rotor 2 in the rotary drum 1 is changed, it is not necessary to move the drive motor base and the setting can be easily performed. When the pressure is not applied to the raw material A due to the consumption of the holding blades 4 and the quality deteriorates, the quality can be maintained by changing the set position. In the conventional machine, when the position of the rotor set is changed, it is necessary to move the drive motor base by the same dimension to check the tension of the chain, which is very time-consuming.
