摘要
文中以江西某矿山脱硫尾矿为研究对象,通过对其分级脱水生产工艺进行试验研究,结果表明,若采用“旋流分级器+陶瓷过滤机”的脱水生产工艺,入料浓度控制在50%以上,过滤机滤饼较厚且较稳定,平均厚度为15.1 mm,陶瓷过滤机台效为56.72 t/h,单位面积处理量为0.71 t/(m^(2)·h),滤饼水分14.41%,但细粉料颗粒含量较多。若采用“旋流分级器+陶瓷过滤机+压滤机”的脱水生产工艺,沉砂尾矿+200目占80%左右,滤饼较厚,但滤饼厚薄不均匀,平均含水率约18%;而溢流尾矿平均压滤时间大约13 min/板,每板压矿量平均为2.44 t,滤饼水分整体较高,对整体分级脱水工艺环节精细化控制要求较高。
Taking a research target of a mines in Jiangxi as a research object,the production test of its classification dehydration production process is conducted.The results show that if the dehydration production process of the"spin-stricken classifier+ceramic filter"is used Above,the filter filter cake is thicker and stable,with average thickness of 15.1 mm,ceramic filter table efficiency of 567.2 t/h,and the unit area processing volume is 0.71 t//(m^(2)·h),and the filter cake water is 14.41%,but fine powder materials,but fine powder materials There are more particles.If the dehydration production process of the"spin grades+ceramic filter+filter machine",the sand tail mnies+200 meters account for about 80%.;The average filtration time of the overflow tail mine is about 13 min/board,and the amount of compression per plate is an average of 2.44 t.The overall water of the filterc ake is high,and the refined control requirements for the overall classification dehydration process are high.
