本文根据赛得瓦兰杰(Sydvaranger)大型球磨机的使用经验,建议大型球磨机的设计可遵循以下原则:1)按比例扩大因素以D~(2.5)为主,使用转矩臂模型,在实际工作状态下,该模型公式的难点主要为确定操作条件下磨机负荷的合适休止角.2)避免过分扩大试验数据,否则将导致休止角的估计值不准确.3)因为最大矿粒需缓慢磨碎,故对于处理粗给矿的大型磨机,磨矿时间是一个重要因素.
Based on the experience of using Sydvaranger’s large ball mill, it is suggested that the design of the large ball mill should follow the following principles: 1) Proportionally expanding factors are mainly D 2.5, and using the moment arm model, State, the difficulty of the model formulation is mainly to determine the appropriate angle of repose for the mill load under operating conditions.2) Avoid over-enlarging the test data otherwise the inaccurate estimate of the angle of repose will be inaccurate.3) Because the maximum ore needs to be slowly milled Broken, so for dealing with rough to the large mill, grinding time is an important factor.
