利用半值磨矿能法(half-valuegrindingenergy)可以得到关干粉磨和所需能量的磨矿实验的综合评价。对各种类型的衬板进行了研究。由于选择了不同的磨矿条件,就需要不同的衬板。可以发现,对于这些材板,半值磨矿能具有较大范围。在研磨<5mm水泥熟料的情况下,对于所研究的各种类型的衬板,可以得到同样数值的半值磨矿能。在颗粒粒度>160um时,磨矿的条件应该这样选择,以使应力足够大到可以破碎粗颗粒的物料。在粒度≤160um时,能量的最佳利用(即最小的半值磨矿能)发生在其它磨矿条件。因此工作参数必须要使每种衬板适应于要研磨的物料,适应于给料粒度的分布和所要研磨产品的细度。这就意味着应考虑一段磨矿。
The use of half-value grinding energy (half-valuegrindingenergy) can be related to dry grinding and grinding energy required for the comprehensive evaluation of the experiment. Various types of liner were studied. Due to the choice of different grinding conditions, different linings are required. It can be seen that for these boards, the half-value grinding can have a wide range. In the case of grinding <5 mm cement clinker, the same value of half-value grinding energy can be obtained for each type of liner studied. When the particle size is> 160um, the conditions of grinding should be chosen so that the stress is large enough to break the coarse particles. At particle sizes <160um, the best use of energy (ie, minimum half value grinding energy) occurs in other grinding conditions. Therefore, the working parameters must be such that each liner is adapted to the material to be ground, adapted to the distribution of the feedstock particle size and the fineness of the product to be ground. This means that some grinding should be considered.
