如何做到合理补加钢球？
答案
参考答案：
日常生产中要定期检查球磨机的球荷总量以及它们粒度组成，了解各种尺寸钢球磨损情况，及时校正补加钢球重量和比例，保持钢球的粒度组成与初装球粒度一致。磨损后形状不规则碎球积留太多时会影响磨矿效果，应定期清理。钢球一般6-10个月清理一次，铁球2-4个月清理一次。

| War, money and power are a few things that countries and people are concerned about. 1 I agree that those things are important, I believe that everyone should start to 2 more on a growing problem-global warming. Global warming will not only 3 our country and our generation, but also-the entire 4 and future generations. It is 5 because the weather has been a lot warmer over the past few years, which 6 the melting (融化) of the ice in the Antarctic. This will soon cause water levels to 7 and flood parts of the world. Many people ignore this problem because they feel 8 they can't do anything about it and have more 9 things to worry about. If we all 10 so, then our ozone layer (臭氧层) will be 11 and the planet will no longer be able to make life continue to exist. We should do our best to limit the use of our planet's 12 resources (资源) and keep our air clean 13 , future generations will suffer from our 14 . Some might feel that they can't stop global warming from 15 . But if every single person does his or her part in keeping the air clean, then it will become a 16 effort. Sure, there are some things that cause pollution and that we won't be able to 17 change. This may include cars burning oil, but we can 18 adjust some of these things. People can start carpooling, taking the bus, riding their bikes, or 19 just walking. If everyone takes 20 now, I believe we can start seeing remarkable results within a few years. | ||||
