The search of optimal compositions for different kinds of coal (lignite and hard coals) with the slam of lean coal for briquettes production was done. Some cheap and non-toxic binders for increasing mechanic stability and water resistance of coal-slam briquettes were experienced. Tree best kinds of binders from coke-chemical industry wastes for improving the properties of coal briquettes were chosen. The main technological parameters of coal briquetting without a binder additive - humidity, size of the pressed coal (dried), pressing pressure, drying temperature and pressing duration are in a certain relationship. To obtain a given briquette strength when changing one of the parameters, it is necessary to change another or several parameters. The dependence of the mechanical strength of briquettes on each individual parameter is often extreme. The value of the parameter at which the maximum strength of the briquettes is obtained is taken as optimal. For coals with good briquetting properties, this extreme dependence of the mechanical strength on individual briquetting parameters is more pronounced, especially for the bending and compressive strength of briquettes. Therefore, in the production of briquettes, an important element in the composition of the coal composition is the binder. The article discusses the search for a binder for the production of fuel briquettes using various grades of coals based on local raw materials.
