Description of the Related Art Conventionally, clay roof tiles have been manufactured from raw clay, which is mainly residual clay and sedimentary clay obtained from the production area, and at present, there is little adverse effect on the quality of products and the overall manufacturing process. Because of the low-grade raw material mixed with foreign substances such as silt, sand, and stone, which need to be crushed and crushed with the depletion of high-quality plain raw material, mainly by a roll crusher. After crushing and crushing the mixed raw material,
It is kneaded with a screen feeder and the waste is extruded with a vacuum clay kneader.

磨耗が激しく耐久性が低い欠点を有している。However, since the roll crusher is crushed by compression, shearing, etc. when passing between two rolls, the crushed product has a rectangular edge shape as shown in FIG. 15 and a knife edge. Therefore, at the time of kneading with a screen feeder or extruding with a vacuum clay kneader, the former screen feeder has an arm for kneading and extruding raw materials, and the latter vacuum clay kneader has a screw and a die die are worn. It has the drawback of being extremely poor in durability.

ある。Regarding the crushing mechanism by the airflow type crusher 1, the raw materials collide with each other in the processing space region X of a constant volume formed by the high-speed swirling vortex airflow in the airflow type crusher 1 and the inner surface of the casing main body and the raw material. Crushes raw material lumps, large stones, minerals such as sand by collision with.

間領域Ｘは形成されない。Regarding the formation of the processing space region X, even if the air is supplied from the air supply pipe 10 to the main swirling vortex space 11 with the damper 8 of the upper casing 4 being fully closed, the inside of the casing main body is still in such a condition. As a result of the increase in the static pressure, the air flow is exhausted from the raw material charging cylinder 14, and at the same time, most of the air supply amount is exhausted from the processed material discharge port 12 while swirling in the lower casing 6, and The processing space region X is not formed in this area.

Ｄが形成される。When the damper 8 is opened and the opening amount of the exhaust port 7 of the upper casing 4 is adjusted, a part of the air supply amount is exhausted from the exhaust port 7, so that the static pressure in the casing body is lowered. , The inner ascending flow path U that rises while swirling between the inner pipe 9 and the processed material discharge port 12 of the lower casing 6.
And the outer descending flow passage D that descends while swirling is formed between the inner ascending flow passage U and the inner peripheral surface of the lower casing 6.

される。At the same time, the air flow sent to the main swirl vortex space portion 11 becomes a main swirl vortex and descends to collide with the raw material feeding cylinder 14 and the lip piece 15 projecting downward from the inner pipe 9. However, since an ultra-high speed vortex flow is generated from such a collision point and the vertical static pressure of the casing body is adjusted by the damper 8, the processing space region X is located in the lower casing 6.
The raw material W, which is formed in the upper portion of the raw material and is charged from the outside by the ejector action of the ultra-high speed vortex, is sucked into the processing space area X by negative pressure suction from the tip end of the raw material charging cylinder 14.

It moves in all directions at high speed along the vortex, and is repeatedly crushed and crushed by mutual collision to be subdivided into pieces. During that time, the adhered water is dried by water repellency or impact heat, friction heat and the like.
【００２２】尚、原料Ｗの自転軸は本体中心線ＣＬに平

経て回収する。Then, after being taken into the main swirling vortex in the processing space region X and processed for a certain period of time, those having a large particle size are moved toward the outer downward flow path D by the centrifugal force toward the inner peripheral surface side of the lower casing 6. The vehicle descends and is guided to the exhaust port 7, and is discharged to the outside by the downward inertial force, and those having a small particle size and mass approach the center side and are collected from the inner ascending flow path U through the exhaust port 7.

And reprocessed.

るため、破砕力、処理密度を調整できる。The damper 8 of the upper casing 4 has a function of adjusting the static pressure itself of the casing body and also adjusting the static pressure above and below the processing space region X, and the upper and lower surfaces of the processing space region X by the lower casing 6 are adjusted. It is possible to stably set the upper and lower positions by utilizing the area difference between the two, and to change the vertical thickness and diameter of the processing space region X by shifting the upper and lower positions to control the centrifugal force due to the main swirling vortex flow. Therefore, the crushing power and the processing density can be adjusted.

Crushing efficiency is improved.

１０％となると放出するメカニズムを繰り返す。Further, the processing space region X is formed by the balance between the air supply pressure on the upper surface thereof and the air pressure flowing into the inner return passage, and the amount of the raw material W which can be retained in the processing space region X is constant, and the retention thereof. Since the crushed particle size changes with time, it is possible to adjust the particle size by changing the input amount. Specifically, when about 100% receives the raw material supply and becomes about 110%, about 20 to 30% of the processed product is released. To about 80-90%, continue to accept the raw material W until the next release,
When it reaches 10%, the release mechanism is repeated.

によって維持する。The processing space region X is formed near the upper portion of the lower casing 6 and is related to the diameter reduction angle of the lower casing 6. If the upward acceleration of the centrifugal acceleration of the main swirling vortex is too large, the processing space is increased. The region X rises and disengages from the upper portion of the lower casing 6, and the processing space region X is destroyed and loses its function. Therefore, it is maintained by adjusting the air supply speed and the static pressure by the damper 8.

It was confirmed that the corner disappeared and the corners were rounded.

With respect to the durability of the vacuum clay kneader due to wear, conventionally, maintenance such as repair and maintenance was required in about 3600 hours, but according to the present invention, it was about 4000 hours. Regarding shrinkage deformation (strain) during drying and baking, conventionally, the shrinkage during drying was about 5.5% and the shrinkage during baking was about 4.5%. Was about 5%, and shrinkage during firing was about 4%. Regarding other factors such as water absorption and bending strength, in the past, the water absorption was about 5.5% and the bending strength was about 2800.
However, according to the present invention, the water absorption rate is about 4.8%,
The bending strength was about 3000N.

ものと思われる。The reason for the above is that since the particles move smoothly along with the movement of water in the present invention, the stress in the substrate becomes small and the free water during drying and the contraction when adsorbed water during baking are removed. It is believed that this is due to the difference in the amount of movement of particles due to the original uniformity or non-uniformity of the orientation of the particles.

In a method for producing a clay roof tile, which comprises a step of kneading and extrusion molding to form a clay roof tile body, in a hollow casing main body of an air flow type crusher 1, an air flow is formed into a swirling vortex flow to form a processing space region X of a constant volume. And the raw materials W are crushed by colliding the raw materials W in the processing space region X, the shape of the pulverized product is flat, and the corners are rounded, so that the arms of the water mixing machine generated at the time of kneading or extruding The wear of the screw, die and the like in the vacuum clay kneader can be reduced, so that the durability of the water mixer 2 and the vacuum clay kneader 3 can be improved, and the corners of the pulverized product are rounded, so that the orientation of the particles can be improved. Since the property is good (uniform), the internal stress (stress) of the substrate is small, the shrinkage during drying and firing is small, and the dimensional accuracy can be improved.

The effect is enormous.
