Thankfully, the performance of the vertical mill was still better than the ball mills, which reinforces the use of this technology.
DetailsBall-mills are used widely for secondary grinding. Loveday 2010 reported on laboratory tests in which small pebbles 7-25 mm were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.
DetailsMar 26, 2021 If the grinding product is too coarse, the monomer dissociation degree of the mineral is low if the grinding product is too fine, it will easily cause the material to be over ground, which will not only increase the energy consumption of the ball mill and the consumption of the grinding medium, but also reduce the productivity.
