近几年来,国内一些电厂采用了引进的大型滚压式中速磨煤机,中速磨虽然在煤种的适应方面不及低速钢球磨,但在其适用范围内与钢球磨相比,却明显地表现了很高的经济性,它具有电耗低、噪音小、金属磨耗少、建设投资省、设备紧凑占地少等优点。尽管如此,我国电厂对中速磨的应用和管理还缺少成熟的经验,更由于磨煤机选型配套和制粉系统整体设计不合理等问题,使中速 In recent years, some domestic power plants have adopted the introduction of large-scale roller mill medium-speed mill, medium-speed mill although less adaptable to the low-speed steel ball mill, but its scope of application compared with the ball mill, but significantly It shows the high economy, it has the advantages of low power consumption, low noise, less metal abrasion, construction investment, compact equipment footprint and so on. However, China’s power plant on the application and management of medium speed mill is still a lack of mature experience, but also due to coal mill selection and milling system unreasonable overall design issues such as the middle speed
