节能球磨机是怎样工作的

分级机下开口高低、分级机下开口大小、分级机上开口高低、分级机上开口大小是在设备安装期间进行现场制作,在许多选厂,因为在设备安装中分级机开口大小高低没有进行调整好,而工人在操作过程中又不太留意,无形也是影响了磨矿作业。分级机下开口低,相对是矿砂沉淀区大了,所以返砂量将大,磨矿细度相对细,分级机下开口大,相对是矿砂沉淀区大了,水流较为平缓,所以返砂量将大,磨矿细度相对细,分级机上开口低,返砂量相对大,磨矿细度相对变细,分级机上开口大,相对返砂量相对大,磨矿细度相对变细。否则相反。我们要假定其它影响因素一切正常,原则是:在磨矿细度一定的情况下,我们要最大化地提高处理量,这样可以有效地提高生产效率。(大部分矿石,特殊矿种除外)相对而言,磨矿细度越细,有用矿物与脉石矿物的解离越充分,对提高金属的回收率有利,所以在处理矿量一定的条件下,尽可能地提高磨矿细度。另外,磨矿是选矿工艺的第一环节,为了保证生产的稳定,磨矿要尽可能的保证稳定。 在给矿量一定的情况下,排矿口处冲水大小、给矿量大小直接影响磨矿的细度粗细,在国内许多矿山现没有实现磨矿自动化,水量的大小,直接由球磨工进行手动调节,因为这两处的水流较大,增大与减小很难看出,所以必须要求进行细致的观察与细微地调整。首先我们一定要明白,节能球磨机给水增大,磨矿浓度变稀,磨矿细度会变粗,相反,节能球磨机给水减小,磨矿浓度变大,磨矿细度会变细。节能球磨机排矿口处冲水变大,溢流变稀,溢流细度变细。相反,节能球磨机排矿口处冲水变小,溢流变浓,溢流细度变粗。所以在其它条件包括矿量不变的情况下,要提高磨矿细度,可以把节能球磨机给水减小,节能球磨机排矿口处冲水增大,最好这两个条件同时调整,以保证尽可能减小因为磨矿细度的调整引起矿桨量的变化因而引起浮选的波动。

Classifier opening height and the classifier opening size, classifier opening level, the classifier opening size is during the installation of on-site production. In many plant, because in the equipment installation classifier opening size and height are not adjusted well, and workers in the operation process and not so aware, intangible and affects the grinding operation. Classifier with low opening, the relative is ore precipitation area big, so the returned sand amount will, grinding fineness is relatively fine, classifier under large openings, is relatively ore precipitation area big, the water flow more quietly, so back to the sand content will, grinding fineness is relatively fine, classifier with low opening, returned sand amount is relatively large, grinding fineness is relatively thinner, classifier on a large opening, relative return sand content relatively high, grinding fineness became relatively thinner. Otherwise. We have to assume that other factors that affect the normal, the principle is: in the grinding fineness of certain circumstances, we must maximize the amount of treatment, so that we can effectively improve the production efficiency. (most of the ores, with the exception of the special types of minerals) in relative terms, grinding fineness finer, the dissociation of useful minerals and gangue minerals more fully, to improve metal recovery rate favorable, so in the amount of ore handling certain conditions, as far as possible improve grinding fineness. In addition, grinding is the first part of mineral processing technology, in order to ensure the stability of production, grinding to ensure the stability of the. Under some conditions to the ore, row ore mouth at flush size, to the amount of ore size directly affect the thickness of the fineness of ore grinding, in many domestic mines now did not achieve the grinding automation, the size of the water directly by ball grinder were manual adjustment, because of the large flow, increases and decreases it is difficult to see, so must require careful observation and fine tuning. First of all, we must understand that the energy saving ball mill feed, grinding concentration of dilute, grinding fineness will become rough, on the contrary, energy-saving ball mill feed, grinding concentration becomes large, grinding fineness will become fine. The port of discharge at flushing energy-saving ball mill becomes large, overflow overflow fineness dilute flow. On the contrary, such milling discharge mouth flushing overflow becomes small, thick, thick overflow fineness. So in other conditions including ore quantity is unchanged and in order to improve the grinding fineness, can reduce the energy saving ball mill feed, energy saving ball mill discharging mouth at flushing increases, the best the two conditions are adjusted at the same time, in order to ensure as far as possible to reduce because the grinding fineness adjustment caused by fluctuations in the ore oar volume changes due to the flotation.
