我厂是利用自产低品位磷矿加工磷肥的小厂,磷矿浮选车间的设备基本上是土法上马自制的。其中主要设备之一球磨机制成后没有轴瓦,怎么办?工人们发扬了一不等、二不靠、三不伸手要的精神,由手扶独轮车使用枣木轴瓦联想到球磨机能否使用枣木轴瓦的问题,当即进行试验,经过几次改进以后,终于成功。制作方法材料必须用干的长枣枣木,这种木料木质细、有韧性、耐磨。我厂使用的枣木轴瓦长为700～800毫米,宽为170～190毫米,高300毫米(见图)。轴瓦所挖弧度占球磨机空心轴半径以下约30～40％之间,球磨机规格为(?)1300×1600毫米。作好的轴瓦,需用沙纸磨光,然后置于柴油或机油中煮至深红色为止,以增加其润滑度。轴瓦中不必加刻油槽,运转期间的润滑可用一 Our factory is the use of low-grade production of low-grade phosphate rock phosphate processing plant, phosphate rock flotation plant equipment is basically homemade. One of the main equipment is made of ball mill does not have a bearing, how to do? Workers carry forward a range, two do not rely on, three do not reach out to the spirit by hand wheelbarrow jujube bearing think of the ball mill can use date wood Bearing the issue immediately test, after several improvements later, finally succeeded. Production methods The material must be dried long date jujube wood, this wood is fine wood, toughness, wear-resistant. Jujube wood bush used by our factory is 700 ~ 800mm in length, 170 ~ 190mm in width and 300mm in height (see photo). Bearing excavation of the arc accounted for the ball mill hollow shaft radius of about 30 to 40% below, the ball mill specifications (?) 1300 × 1600 mm. To make the bearing, sandpaper to be polished, and then placed in diesel or oil until dark red so far to increase its degree of lubrication. Needless to add bearing groove in the bearing, lubrication during operation can be used one
