How much do you know about the classification of refractory clay factory? Let's have a simple understanding together!

The refractory clay factory is divided into four types: soft clay, semi-soft clay, hard clay and high alumina clay according to plasticity, mineral characteristics and industrial use. Soft clay is generally soil-like, easily dispersible in water, and can form plastic mud mass after mixing with liquid; semi-soft clay has poor dispersibility, and its dispersing part can also form plastic mud mass after mixing with liquid . These two kinds of clay are often used as binders when making refractory products. Hard clay is often in block or plate shape, generally does not disperse in water, and has high refractoriness. It is the main raw material for refractory products. High alumina clay has high content of Al2O3, high hardness and specific gravity, and high refractoriness. It is often used to manufacture advanced clay products.
The above is a brief introduction to the classification knowledge of refractory clay factory.
