无论是普通浓缩机还是借助添加絮凝剂的高效浓缩机,现其结构均有稳步的进展。在选矿过程中,浓缩机普遍用来浓缩尾矿以回收工艺用水和在过滤前浓缩精矿。浓缩机是逆流倾析工艺的组成部分,且经常用作缓冲贮存设施和用于浮选产品的中间脱水。浓缩机一般要同时完成两项功能,即生产出高浓度的底流和洁净的澄清液,且工作时通常很平稳,一般不用注意看管。但若发生故障或者规格不合适,则对生产能力有很大影响。所有的浓缩机均是借助重力来沉降固体物料的。给料自液面或其附近给入,驱动机构使耙子回转扫集沉降的固体物料到中间的底流锥中。浓缩机的规格大小取决于被浓缩矿浆的性质。有些矿浆的沉降会在上层澄清 Whether it is ordinary thickener or by adding flocculant efficient concentrator, now its structure has been steady progress. In the beneficiation process, thickeners are commonly used to concentrate the tailings to recover the process water and to concentrate the concentrate prior to filtration. Thickeners are an integral part of the countercurrent decant process and are often used as buffer storage facilities and for intermediate dewatering of flotation products. Thickeners generally have two functions to be completed simultaneously, that is to produce a high concentration of underflow and clean clear liquid, and work is usually very smooth, generally do not pay attention to care. However, if there is a malfunction or the specifications are not suitable, the production capacity will be greatly affected. All thickeners use gravity to settle solid materials. Feeding from or near the surface of the feed, the drive mechanism so that the rake rotary sweeping sediment solid material to the middle of the underflow cone. The size of the thickener depends on the nature of the slurry being concentrated. Some pulp settling will clarify the upper
