在选矿厂中,磨矿-分级是关键性的作业之一,其任务是为后续选别作业提供既充分单体解离而又不过粉碎的给料。国内外选矿界业已公认,如果不采取某种形式的自动控制,则磨矿-分级效率无从提高,因为整个磨矿回路受到各种随机干扰;同时也公认,利用数学模型通过电子计算机对回路进行模拟,有助于研究和评价各种可能的控制决策。因此,球磨机和水力旋流器的为数众多的数学模型已被研制出来,
In the concentrator, grinding-grading is one of the key tasks with the task of providing a feedstock that is both sufficiently monomer-free and not crushed for subsequent sorting operations. It has been recognized by the domestic and foreign mineral processing community that without some form of automatic control the grind-grade efficiency can not be increased because the entire grinding circuit is subject to a variety of random disturbances and it is also recognized that the use of mathematical models for circuit-by- Simulation helps to study and evaluate various possible control decisions. Therefore, a large number of mathematical models of ball mills and hydrocyclones have been developed,
