我们选用了φ1×5米圆筒型干燥机作为大悟县大悟萤石矿浮选精矿的干燥设备。经过一年多的使用,效果不佳、当进料水分平均为15%,出料水分在1%以下时,干燥机单位容积蒸发水量的能力仅为14.4(公斤/米~3·小时),显然是太低了。为此,我们对该机进行了研究与改造。 (一)干燥系统生产流程经过沉淀后的湿物料水分约15%,用人工装入0.5米~3手推式斗车,然后倒入1米~3的缓冲漏斗中,再经φ200×3000 We chose the φ1 × 5m cylinder dryer as Dawu County fluorite flotation concentrate concentrate drying equipment. After more than a year of use, the effect is not good. When the average moisture content is 15% and the moisture content is less than 1%, the unit capacity of the dryer is only 14.4 (kg / m3 ~ 3h) Obviously too low. To this end, we carried out research and transformation of the aircraft. (A) drying system Production process After the precipitation of wet material moisture about 15%, manually loaded 0.5 m ~ 3 hand push bucket car, and then poured into 1 m ~ 3 buffer funnel, and then by φ200 × 3000
