The optimization of low-rank coal grinding for

2012-5-1  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.

Grinding analysis of Indian coal using response

2016-6-27  Three parameters ball charge (numbers 10–20), coal content (100–200 g) and the grinding time (4–8 min) were chosen for the experiments as well as for the modeling work. Coal fineness is defined as the d80 (80 % passing size). A quadratic model was developed to show the effect of parameters and their interaction with fineness of the product.
