The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.
Prominer is experienced in choosing the suitable grinding mill to reserve high yield rate of big flake graphite. With the development of expanded graphite and anode materials industry, there is much requirement on high purity graphite product. It is very hard to reach the grade above TGC 96% just by the stage grinding and flotation processing.
Hypothermal deposits are formed at great depths and high pressures and temperatures.Temperatures may range from 300° to 500° Celsius during the formation of such deposits. Casseterite, wolframite and molybdenum veins; gold-quartz veins; copper-tourmaline veins; and lead-tourmaline veins provide examples of mineral associations which may occur …
The initial heat generation is virtually adiabatic leading to high grain contact temperatures approaching the workpiece melting temperature.Rowe [4]. This means the temperature of the grinding chips as they are produced is very much higher than the surrounding background temperature in the contact zone. It A, =
Due to the high steam temperature of over 300°C and due to the increase of the particle surface in the grinding process, the moisture contained in the particles is evaporated. Furthermore, S-Jet mills offer the possibility of drying or at …
