在生产过程中,螺旋分级机槽体长期浸泡在矿浆中被矿砂摩擦,槽体逐渐被腐蚀、氧化、磨损,最终导致槽体钢板穿孔漏矿。虽经补焊,但穿孔、漏矿现象频繁发生(也证明槽体到了更换周期)。每处理一次漏矿要经过停产、吊出大轴、挖矿、找泄漏点、补焊及装大轴等许多步骤,一般需要用1个班的时间。这样不但工人劳动强度大,生产也受到损失。 In the production process, spiral classifier tank long-term immersion in the pulp by the sand friction, tank gradually corrosion, oxidation, wear and tear, and eventually lead to the tank plate perforation mine. Although the repair welding, but perforation, frequent mine leakage (also proved that the tank to the replacement cycle). Each treatment of a mine to go through the shutdown, hanging out of the shaft, mining, to find leaks, repair welding and installation of large shaft and many other steps, the general need to use a shift time. This will not only result in the heavy labor intensity of workers but also the loss of production.
