In thermal power plant, coal mill pulverizer is used in the milling process to crush and grind coal into powder SBM offer types of coal mill for powder plant Get Price And Support Online Pulverizer - Wikipedia A pulverizer or grinder is a mechanical device for the grinding of many different types of materials For example, a pulverizer mill .
Feb 28, 2012 But it is limited by the number of mills and cannot achieve high-precision ratio of blending. To remedy this shortcoming, a model of two-level optimization of coal blending for the thermal power plant with direct blowing pulverizing system was established in this paper. The tradional coal blending was regarded as first step of optimization.
