小于74微米物料的粒度分析,在选矿、冶金生产和试验研究中是不可缺少的一环。在建材、水利、土壤、煤炭、环保等部门也广泛应用粒度分析技术。我国自六十年代以来,一直采用连续水析器作为分析74微米以下物料的主要手段。这种方法操作时间长,结果的重现性差,对生产中的考察及试验研究工作不能及时提供数据,影响试验工作进度。旋流水析仪应用离心力场代替重力场,使物料在离心场中加快了沉降速度,克服了
Particle size analysis of materials smaller than 74 microns is an integral part of beneficiation, metallurgical production and experimental research. In building materials, water conservancy, soil, coal, environmental protection and other departments are also widely applied particle size analysis technology. Since the 1960s, China has been using continuous water separators as the primary means of analyzing materials below 74 microns. This method has a long operating time and poor reproducibility of the results. Data can not be provided in time for inspection and experimental research in production, which affects the progress of the testing work. Centrifugal force field to replace the centrifugal force field gravity meter, the material in the centrifugal field to speed up the settlement speed, to overcome
