粒度分级 - Use : purpose : hierachial machine extensively suitable for metal ore dressing procedure go on grain size grade to ore pulp , take off the mud , dephydrates , often makes up the closed procedue with the ball mill when can be used for wshing the homenork
用途：螺旋分级机广泛适用于金属选矿流程中对矿浆进行粒度分级，也可用于锡矿作业中脱泥、脱水，常于球磨机组成闭路流程。 - The mainly work has : the relation of boron contents and the average liner burning rate , through which chooseing suitable boron contents in these delay compositions ; the impact of different particle diameters on delay characteristics , by the means of granularity classfication ; the impact on delay characteristics through pre - treatment to the raw materials and improvement of mixing means ; and some other factors , such as the pressure of charge , loaded times , the charge mass of delay composition ; at last , the mechanical intensities of boron based delay compositions with some different binders
主要的研究内容有： b含量与线性平均燃速的关系，并由此选用b含量适合的延期药；通过原材料的细化与粒度分级，研究了粒度对延期性能的影响；原材料预处理和混药方式对延期性能的影响；以及影响延期性能的其它因素，如压药压力、压装次数、装药量等；最后还研究了含不同粘合剂的硼系延期药的压药药柱强度(机械强度)等。
