The coal was crushed in the Coke Department of Cze-stochowa Plant. The numerical determination of grain size distribution of crushed coal was made, and the re-sults obtained in this way were compared with the re-sults of laboratory analyzes of grain made. In this pur-pose, the results of the grinding process in a hammer crusher (Figure 1).
Grinding Action is carried out by a series of hinged or fixed hammers revolving in an enclosed chamber with wear-resistant plates. The hammers impact on the coal, crushing it against the plates. Further pulverization of coal is achieved as the smaller coal particles are ground through attrition against each other and the grinding face.

For fast and effective pre-crushing of very hard, hard, medium-hard, brittle materials, even ferrous alloys. Size reduction from 95 mm to 0.3 mm.
Initially, this focused on grinding coal and the cement raw materials, with the adoption of vertical roller mills for cement product grinding - with its finer grinding requirements - coming more ...
Reference proposed a nonlinear three state dynamic model of coal mill, in which the grinding relationship of coarse to fine particle was also presented. Based on the proposed model, the dynamic performance under start-up and normal condition can be predicted, and a model-based predictive control was designed for better load tracking and ...
In order to monitor the wear condition of grinding roller of coal mill in power plant and improve the reliability of production equipment, it is necessary to establish a state monitoring model with high accuracy and good prediction effect. It has been shown that the power of coal mill can reflect the wear degree of grinding roller. If the voltage and power factor of coal mill are constant ...

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...
