The results show that TEA is more effective in ball mill than in vibrating disk mill It increases the Blaine specific surface area of the mixtures of 95 % clinker and 5 % gypsum by 16 and 7 6 % in ball and vibrating disk mills respectively compared to the blank test The cement samples produced from the two mills were then tested for their initial and final setting times spread diameter as

Continue ReadingEnergy consumption for ball mills is a function of many factors: the physical properties of the ground material – its specific gravity and hardness the degree of drum filling by grinding balls the number of drum rotations etc Ball mills have low efficiency – no more than 15% Energy is mainly consumed on the wear of grinding balls and mill housing friction heating the material etc
