Abstract: Grinding roller and refiner plate are the core components of the coal mill, which is one of the most important equipments in the thermal power plants. In this paper, the operating condition and principle of the grinding roller and refiner plate are analyzed. In addition the current situation of ceramal compound roller and refiner plate manufacture is elaborated. And the new techniques for the preparation of the ceramal compound roller and refiner plate are introduced. In contrast with the products using the conventional techniques, the service life of those manufactured with the new techniques almost doubles, and the grinding efficiency is also greatly improved, which shows significant direct and indirect economic benefits.

Key words: power plant, medium speed mill, ceramal compound material, grinding roller, refiner plate
