RP863磨煤机磨辊防磨罩的设计和应用

Design and Application of Anti-abrasion Cover for Grinding Roller of RP863 Coal Mill

为降低火力发电厂生产成本,提高发电经济性,燃煤电厂使用成本较低的低热值煤进行掺烧。低热值煤具有灰分高、可磨性差的特点,掺烧工作使制粉系统设备面临更加严重的磨辊磨损问题。通过设计和应用RP863磨煤机磨辊防磨罩,降低磨辊重要部件的磨损,适应企业掺烧低热值煤需求。

In order to reduce the production cost of thermal power plants and improve the economic efficiency of power generation, coal-fired power plants use low calorific value coal with lower cost for blending combustion. Low calorific value coal has the characteristics of high ash content and poor grindability. Mixing burning makes the equipment of pulverizing system face more serious problem of roller wear. Through the design and application of the anti-wear cover of the grinding roll of RP863 coal mill, the wear of the important parts of the grinding roll can be reduced, and the requirement of blending low calorific value coal in enterprises can be met.
