nihil molestiae consequatur

Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

The brightness of a kaolin is an important property because it determines the potential uses and prices. In general, the higher the brightness of the kaolin the more value the kaolin has. Standard brightness values are measured at a wavelength of 457 nm, and a common standard against which the samples are compared is smoked magnesium oxide. As

Different Types Of Clay Used In Making Ceramics African

The poor plasticity of kaolin is chiefly due to its relatively large particle sizes. Consequently, pre-fired kaolin ceramics can easily tear when bent, if in a moist unfired state (i.e. moisture levels are suboptimal). Of all classes of clay, kaolin has the highest temperature maturity levels (high-fire clay) with temperatures as high as 1,800 °C.

Calcined kaolin diminishes the weak zone between slurry during mixing [24]. Lecomte et al.

Kaolin has poor pore structure and thus leads to lower hardness performance than calcined kaolin.
