Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a porcelain aggregate which is laid on the surface of a road and used as a color code for the road surface or as a slip stopper.

[0002]

2. Description of the Related Art A conventional method for manufacturing a porcelain aggregate is SiO 2.
₂ , Al ₂ O ₃ , Na ₂ O, K ₂ , porcelain matrix composed of metal oxides and the like is compacted into a block, which is first fired at high temperature to form a brick, and the brick is crushed, for example, 5.5
~ 3.3mm, 3.3-2.0mm, 2.0-1.0mm, 1.0
The particles were sorted into 0.5 mm sized particles.

[0003]

Generally, in the manufacturing process of the porcelain aggregate, a considerable amount of grains finer than 0.5 mm are generated. However, the fine particles generated by the conventional manufacturing method cannot be reused as the porcelain aggregate, and there is a problem that there is much waste. In other words, if fine particles below the specified value are collected and baked again on the brick, the porcelain body will be baked twice, and the color of the finished porcelain aggregate will not change without using such regenerated particles. It is not the same as the manufactured porcelain aggregate.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, in which an unsintered porcelain base is compacted into a lump , which is naturally or
Is the first step of forcibly drying , the second step of crushing the lumpy porcelain body produced in the first step before firing, and selecting the grains of any size, and the porcelain produced in the second step a third step of firing a particle of greenbody consists, first Engineering said second generated in step prescribed value or less fine grain
It is intended to provide a method for producing a porcelain aggregate that is returned to a normal state and reused .

[0005]

[Operation] The lumpy porcelain body made in the first step is dried
It's hard and hard, so crushing it into grains with a square surface.
It If the particles are baked at high temperature in the third step, the road surface will not slip.
A good quality porcelain aggregate that can be used for on the other hand,
In the second step, fine particles below the specified value are generated, so
Fine particles are collected by shaking off in the process of selection. This rule
Fine grains below a certain value have not been fired yet, so
Since it is the same as the porcelain base used in one process,
The fine particles generated in the two steps are returned to the first step for reuse.
You can

DESCRIPTION OF THE PREFERRED EMBODIMENTS The manufacturing method of the present invention will be described below with reference to the block diagram showing the manufacturing process of FIG. First, in the first step, the porcelain body is pressed into a block and solidified. The porcelain matrix used is, for example, SiO ₂ , Al as in the prior art.
It is a mixture of ₂ O ₃ , Na ₂ O, K ₂ and a metal oxide, but this porcelain base may be any one suitable for a porcelain aggregate. In addition, means for compacting the porcelain frugal place to massive, making the mud by grinding the porcelain raw materials in a mill, this
The sludge is dehydrated with a filter press and then dehydrated and solidified.
The porcelain base that has become trapped is dried naturally or forcibly.

Next, in the second step, the lumpy porcelain green body produced in the first step is crushed in an unfired state, and from there, for example, 5.5 to 3.3 mm, 3.3 to 2.0 mm, 2 0.0-1.0m
Grains with a size of m, 1.0 to 0.5 mm are selected. Specifically, for example, a porcelain greenbody bulk was pulverized so as to rub the wire mesh plates, we sorted toward crushed grains further vibrating screen machine that has passed through the wire mesh plate. The grains thus made are porcelain
Since the organic base is dry and hard, crush the fired brick
There is almost the same squareness as conventional grains that can be made.

Then, when the particles of the porcelain green body are fired at a high temperature in the third step, as shown in FIG.
A certain porcelain aggregate 1 is created. When firing,
Ideally, the grains of the porcelain base material should not touch each other , but if this is done, the amount of porcelain aggregate 1 that can be fired at one time will be extremely small and the productivity will deteriorate. Therefore,
Actually, a certain amount of porcelain base particles are put in a box-shaped sagger and then baked. Then, the grains of the porcelain porcelain aggregate 1 may stick to each other in the casket with a slight bonding force, so that a process of loosening and breaking them apart is supplementarily added. In this step, the lumps of the porcelain aggregate 1 are rubbed on the mesh plate, and the grains that have been separated and passed through the mesh are further passed through a vibrating screener. Needless to say, this step is not essential, and it is not necessary if it can be fired in the third step in a state where the grains of the porcelain body do not stick to each other.

[0009] Therefore, below the specified value generated in the second step.
The fine grains below are returned to the first step and reused. This rule
Fine grains below a certain value are new because they have not been fired yet.
It is the same as the porcelain base material. Therefore, the fineness below the specified value
Porcelain aggregate 1 made by mixing paddle grains
Completely the same quality as porcelain aggregate 1 made without mixing granules
Is.

The porcelain aggregate 1 can be laid on a paved road surface and used as a color code for the road surface or as a slip stopper for the road surface. In addition, it has a wide variety of uses, such as being able to be mixed with a wall material of a building or used as a stone to be planted in a garden.

[0011]

As described above, in the method for producing a porcelain aggregate according to the present invention, the porcelain base that has been solidified in a lump form and dried is crushed into granules before firing.
You can easily create certain grains. Therefore, the road surface
When it is laid on the floor, it should exhibit sufficient anti-slip function.
You can Also, the fineness below the specified value generated in the second process
Since the grains were returned to the first process and reused,
High quality porcelain aggregate with low price
There is an excellent effect such as being able to provide.
