根据辊面的冲击纵剖面图的恰当通式,分析了单矿粒在固定安装的辊磨机中的破碎。该模型使得人们可以估价不规则矿粒的等效矿粒-啮角直径,它们约有90％符合标称格筛的直径。与模型一致,单粒石英、白云石、石灰石和赤铁矿破碎所需的能量消耗与等效直径和辊隙间的差紧密相关。根据测试的给矿粒度和辊隙的各种组合,破碎比指
According to the appropriate general formula of the impact longitudinal profile of the roll surface, the fragmentation of single ore particles in a fixedly mounted roll mill was analyzed. This model allows one to evaluate the equivalent grain-nodal diameter of irregular grains, about 90% of which meet the nominal mesh size. Consistent with the model, the energy consumption required for crushed single quartz, dolomite, limestone and hematite is closely related to the difference between the equivalent diameter and the nip. Broken ratio refers to various combinations of grain size and nip to be tested
