在我们的工作中,对一些近年来引进的国外的齿辊式破碎机及新的资料进行了分析研究,对以往的设计计算公式作了一些修正。一、功率计算传统经验公式(公式) N=0.1iQ (千瓦)式中:i——破碎比; Q——生产率,吨/小时。根据赫基(Hukki)1961年所作的能量输入与粒度的关系图分析,齿辊破碎机属于常规破矿范围,宜用基克(Kick)的破碎理 In our work, some foreign countries introduced in recent years, roller crusher and new data were analyzed and studied, the previous design and calculation formula made some amendments. First, the traditional empirical formula for power calculation (formula) N = 0.1iQ (kW) Where: i - broken ratio; Q - productivity, t / h. According to the analysis of the relationship between energy input and particle size made by Hukki in 1961, the roll crusher belongs to the range of conventional rockbolt mining and should be broken by Kick’s crushing theory
