2.7×2.1光球磨机中空轴大瓦,原来的润滑方法,是在大瓦上盖方形孔套内放置一个150×150×120毫米的油盒,油盒底钻成许多小孔,其上铺一层毡垫,稀油透过毡垫滴落到中空轴上,使大瓦得到润滑。但此种润滑方法存在许多缺点,例如毡垫透油性不可靠,油盒过小,润滑油只能滴在中空轴表面很小一部分,油盒装油量少,球磨机运转中注油次数多影响生产等。去年到南芬选矿厂学习先进经验后,大孤山矿二选将“油盒式”改为“油线式”润滑,取得了显著效果。改进前后情况见表1、2。
2.7 × 2.1 hollow ball mill hollow ball, the original method of lubrication is to place a square hole in the big tile cover a 150 × 150 × 120 mm oil box, the bottom of the oil drill into a lot of holes, the shop on a Layer felt, thin oil drops through the felt paddle to the hollow shaft, so that the large tiles are lubricated. However, this method of lubrication has many shortcomings, such as felt oil permeability is not reliable, too small oil box, lubricating oil can only drip a small part of the surface of the hollow shaft, fuel tank filled less, the ball mill operation in the number of oil injection affect production Wait. Last year to Nanfen beneficiation plant learning advanced experience, Dagushan second choice will be “oil box” to “oil-line” lubrication, and achieved remarkable results. The situation before and after the improvement is shown in Table 1 and 2.
