Исследование зависимости качества природного скрытокристаллического графита от режимов подготовки

The research revealed how activation time, type and amount of surface-active additives influenced on an average size and total surface area of crystalline and cryptocrystalline graphite particles, taken from different deposits, and carbon bearing waste materials, during the process of activation in a planetary centrifugal mill, АGО-2. It was shown that the maximum dispersion degree of graphite and carbon bearing waste was achieved within 20 minutes of activation without surface-active additives. The most efficient surface-active additives are additives containing sulfo groups in their structure. The amount of such additive should not exceed 3%.
