我矿选矿厂磁选铁精矿采用12米~2 永磁式过滤机过滤。投产以来,该机暴露了一些问题,如给矿箱漏矿、筒体布料不匀、串风漏气、真空度低、塑料板强度不够等。在学习攀钢经验的基础上,通过反复实践,采取下列措施,使磁滤机满足生产的需要。1.提高给矿管位置,并使管口朝筒体成45°角,取消挡板,提高箱底坡度,加宽密封胶皮,基本解决了由于堵塞而造成的布料不匀的问题。2.给矿箱内溢流槽底改为15～20°的坡度,由单溢流管改为双管使溢流畅通,防止筒体上部因矿浆流动而使滤饼遭到破坏。
I mine concentrator magnetic separation of iron concentrate with 12 m ~ 2 permanent magnetic filter. Since the commissioning, the machine exposed some problems, such as mine leaking mine, cylinder uneven cloth, string leaking, low vacuum, plastic plate strength is not enough. On the basis of learning the experience of Panzhihua Iron and Steel, through repeated practice, to take the following measures to make the magnetic filter to meet production needs. 1. Raise the position of the pipe and make the pipe mouth into a 45 ° angle to the cylinder, cancel the baffle, raise the slope of the tank bottom, widen the sealing rubber, and basically solve the uneven cloth caused by the blockage. 2. To the bottom of the tank overflow tank to 15 ~ 20 ° gradient from single overflow pipe to double pipe so that the overflow flow, to prevent the upper part of the cylinder due to the flow of the slurry cake was destroyed.
