大吉山矿选厂每年可生产钨细泥500吨以上,主要销往日本、美国。按外商要求,钨细泥不能烘烤,只能晾晒。每当天气阴雨潮湿,就无法正常生产,钨细泥的脱水过滤一直没有妥善解决。针对这一问题,大吉山矿与北京有色冶金设计研究总院、江苏省张家港市后塍冷作设备厂共同研制了0.5米~2皮带式过滤机,该机处理的钨细泥细度为-200目80—90%,给矿浓度40—55%,皮带速度0.7—1.5米/分,处理量140—350公斤/时,真空度520—560毫米汞柱,滤饼厚度2—5毫米,滤饼水分10—14%。皮带由1.5千
Dajishan ore processing plant annual production of 500 tons of fine tungsten mud, mainly exported to Japan, the United States. According to foreign requirements, tungsten fine mud can not be baked, only drying. Whenever the weather is wet and humid, it can not be normal production, dehydration and filtration of fine tungsten mud has not been properly resolved. In response to this problem, Dajishan Mine and Beijing Nonferrous Metallurgy Design and Research Institute, Zhangjiagang City, Jiangsu Province Houchuang Cold Working Equipment Factory jointly developed a 0.5 m ~ 2 belt filter, the fineness of the machine to deal with tungsten fine mud - 200 mesh 80-90%, ore concentration 40-55%, belt speed 0.7-1.5 m / min, handling capacity 140-350 kg / h, the degree of vacuum 520-560 mm Hg, filter cake thickness 2-5 mm, Filter cake moisture 10-14%. Belt by 1.5 thousand
