How to pre-process ceramic raw materials?
In the production process of ceramic products, it is first necessary to pre-process the raw materials used, and then to prepare the ceramic products for the raw materials. The main raw materials used in the production of general ceramic products are clay, in the pre-processing process. What do you need to do with ceramic clay?
If the soft clay enters the factory, if there are too many impurities, it needs to be selected in advance. The selection generally uses a precipitation elution method and a hydrocyclone method. The former uses a clay wash basin; the latter uses a hydrocyclone. If there are not many impurities in quartz or feldspar, or only organic matter, the ore can be used directly without treatment.
How to pre-process ceramic raw materials: weathering of clay raw materials:
Weathered clay has the following main functions:
1. Conducive to the crushing of clay;
2. Increasing the dispersion of clay is beneficial to improving the plasticity of the clay;
3. Make the water in the clay uniform. Generally, the weathering period is more than half a year, at least three months.
How to pre-process ceramic raw materials: drying of clay raw materials:
Drying the ceramic raw clay mainly has the following effects:
1, remove excess water, can improve the accuracy of the ingredients,
2. The prepared mud has good fluidity and can shorten the pouring time.
Generally, it is dried by a mantle and a chain plate dryer, and the drying temperature is 100 °C.
