一、引言钢球磨煤机是目前国内火电厂广泛使用的制粉设备,约占火电厂全部制粉设备的70％以上(约1100台)。其运行特点是:安全可靠;便于维护;运行周期长,又可连续保持最大出力;能磨制褐煤,烟、贫煤及无烟煤等煤种。我国火电厂中运转的钢球磨,绝大部分为沈阳重型机器厂产品,分为老系列和新系列。另外也有部分苏制产品。国产及苏制钢球磨均分为筒形及锥形两种。

I. INTRODUCTION Ball mill is the most widely used pulverizing equipment in domestic thermal power plants, accounting for more than 70% (about 1100) of all pulverizing equipment in thermal power plants. Its operating characteristics are: safe and reliable; easy to maintain; long operating cycle, but also continue to maintain the maximum output; able to mill lignite, smoke, lean coal and anthracite coal. China’s power plant operating ball mill, most of Shenyang heavy machinery plant products, divided into the old series and the new series. There are also some Soviet-made products. Domestic and Soviet-made steel ball mill are divided into two kinds of cylindrical and tapered.
