A very important aspect of proper preparation of the coal mixture for the coking process is its appropriate grinding. One of the parameters describing the energy input required for grinding is the Hardgrove index. This research was undertaken to determine the dependence of the Hardgrove grindability index on selected physicochemical properties of coal.
9%The idea is to remove fly ash from the linear coal economy and use it to replace valuable raw materials—natural resources that are already too scarce. Conducting research on materials with RWTH Aachen University in Germany, Vecor discovered that fly ash can be used to produce sand and aggregates, as well as fillers for paints and …

Crushers, grinding mills and pulverizers are types of grinding equipment used to transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. Grinding equipment can be classified into to two basic types, crushers and grinders.
However, flotation experiments show that the maximum actual yield of clean coal first increases and then decreases on increasing the grinding time from 3.5 min to 15 min. Approximately 50% clean coal was obtained at grinding times between 3.5 and 5 min. This can be used for metallurgical plants and has economic value.
