包钢烧结厂162m~2D.L型焙烧机等主要设备系从日本、西德引进,设计能力为年产高炉球团矿110万吨。其中两台国产的φ1.5m×5.7m球磨机用于将球团返矿再次磨碎重新配料。 球磨机两端空心轴采用针阀式注油油杯,利用油的自重一滴一滴地流到轴上,滴落速度随油位改变,使用50~#机械油。 因设备陈旧,负荷大,返矿料温高,磨料时筒体温度有时高达150℃以上。加上此工作间为高粉尘作业区,空心轴两侧密封不
Baotou Sintering Plant 162m ~ 2D.L roaster and other major equipment from Japan, West Germany introduced the design capacity of an annual output of blast furnace pellets 1.1 million tons. Two domestically produced φ1.5m × 5.7m ball mills are used to grind and re-pellet pellets again. Hollow shaft at both ends of the ball mill uses a needle-type oiling cup, using the weight of the oil drop by drop to the shaft, the drop speed changes with the oil level, the use of 50 ~ # mechanical oil. Due to obsolete equipment, heavy load, high temperature return to the material, the barrel temperature of abrasive sometimes up to 150 ℃ or more. Plus this workshop for high dust area, hollow shaft seal on both sides not
