Ball mill for calcination alumina

Aug 31, 2020

Jan 01, 1995 (2) Elevation of calcination temperature increased not only the amount of reduced Na20, but also the induced amount of Si02 in calcined alumina. (3) It was found in wet ball milling of the calcined alumina that the agglomerates were broken down into the primary particle size up to 0.25 h and that the broken down primary particles were ground
