Kinetics of fine wet grinding in a laboratory ball mill
Pumice, with low pozzolanic reactivity, was ground for 1, 3, and 6 h with a laboratory ball mill in dry conditions and it was ground for 1 h in wet conditions via an industrial-scale ball mill. Based on derivative particle distribution, grinding for longer periods led to the disappearance of bimodal distribution and the development of unimodal Bionics Scientific is a leading laboratory ball mill manufacturers in India and offers its customers a fair deal in buying ball mills with facilities of customized size and capacities up to 10 Kg.
