  • The optimization of low-rank coal grinding for transport

    May 01, 2012· 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.

  • Optimization of Crushers and Mills DALOG

    Optimization of Crushers and of Mills Crushing and grinding technology is used to reduce particle size of solid materials such as limestone, ore, coal, or other materials. The process requires a lot of specific forces (typically impact, shear and/or compression), which is challenging for the crusher / mill
