Manufacturing Process
Production process of porcelain clay
We manufacture each product by specific formulation and and proportions.
We mainly use the two manufacturing methods.
Stamper manufacturing
Ball mill manufacturing
These two types of manufacturing methods are introduced here.
The manufacturing method differs slightly depending on the product.
Manufacturing method by stamper
The stamper uses a pestle and mortar to crush the ceramic stone into small pieces to make white porcelain clay.
Ceramic stone grinding
Remove dirt from the ceramic stone and blend it to make it smaller.
This will be blended according to our own harmony and distribution. It is then crushed as it is a joke crasher.
The coarsely pulverized ceramic stone is further refined.
The coarsely ground pottery stone is further refined using a stamper. It takes about 11 hours to become a powder.
The powdered ceramic stone is sucked up by a blower, pneumatically transported, and stored in a hopper.
Sedimentation
The difference in settling speed in water is used to sort coarse to fine particles in stages.
Stirring
Mix the powdered ceramic stone with water using an agitator.
Remove the rough particles.
Further sorting
Extract the finest and cleanest grains of sand.
Precipitation
This fine powder becomes porcelain clay.
It takes two weeks to a month for the fine powder to fill the sedimentation tank.
This is the next step in the process.
Dehydration
Sieve the mud to remove the iron content.
Impurities are removed through a vibrating sieve (75-90 microns). The mud is then passed through a de-ironing machine (electromagnet) to remove the iron content.
Make it into a sheet of clay.
The water is removed by the pressure of the filter press machine, and the clay is made into a plate.
Mix and Concoct
Shape it into a cylinder and pack it.
Remove the air from the clay with a vacuum clay kneader and adjust the hardness to shape it into a columnar shape. We will wrap the product and ship it.
Manufacturing method by ball mill
We use raw materials from all over Japan and the world, such as pottery stone, feldspar, frog-eye clay and kaolin, to make a variety of porcelain clays.
The raw materials and water are placed in a ball mill, and by rotating the mill, the boulders are rolled and the raw materials are ground.
Mixed grinding, in which water is added together, completes the muddy water.
Mixing and grinding
Raw materials such as pottery stones are weighed and put into a ball mill according to the mixture of each product. Water is added and the mixture is crushed into small pieces.
Discharge
The finished muddy water is pumped out and pumped to the tank.
