The optimization of low-rank coal grinding for transport ...

2012-5-1  Highlights KBR transport gasifier is an effective process for gasification of low-rank coal. However, a feed coal for this gasifier has a narrow particle size distribution. Grinding parameters on hammer mill was investigated by Taguchi method. Aperture size of screen in the second hammer mill was the most significant factor. The ratio of product loss was 10.18% under the optimized condition.
