FEATURES: B HEL manufactures a complete range of Bowl Mill (Pulveriser) for all supercritical & non supercritical thermal power plant applications. Pulverisers are one of the major auxiliaries in a coal fired thermal power station . They are used for grinding the raw coal, so that the pulverised product at desired fineness can fed to and directly fired in the furnace of the steam generator.

The ion source generates a low temperature plasma with slow (cold) ions at an ion temperature less than 1eV, which can be extracted from the ion source through the grids with a well-defined energy. In a three grid system, specific potentials or voltages applied between the grids provide the driving force and focussing optic for the ions.
