一、前言翻床的试验于1956年开始,在1958年开始试制,并在生产中推广,经反复改进,于1963年正式定型。定型后的翻床能在运转中调坡以控制产出率;精矿浓度高,不脱水即可满足下一工序的要求;处理能力比自动溜槽增加了一倍左右;并设有控制给矿量的设施,保证了细粒锡石(74～19微米)的有效回收。翻床可作为重选矿泥的粗选设备,经过一次粗选和扫选能丢弃昆矿65～70%。每台生产率为40～75(吨/日),回收
I. Preface The experiment of turning over the bed started in 1956 and began trial production in 1958. It was popularized in production. After repeated improvement, it was formally shaped in 1963. After the stereotyped bed can be adjusted in operation to control the output rate; concentrate concentration, non-dehydration to meet the requirements of the next process; processing capacity than the automatic chute doubled; and control to the mine The amount of facilities to ensure the effective recovery of fine-grained cassiterite (74 ~ 19 microns). Turn the bed can be used as a coarse selection of equipment for re-election slime, after a rough selection and sweep can discard Kunming 65 ~ 70%. Each production rate of 40 to 75 (tons / day), recycling
