on 70% of the coal passing through a 200 mesh screen. Mills are capable of grinding harder coal with higher percentage moisture content and can reduce the product fineness in excess of 90% passing a 200 mesh screen at a reduced output capacity. The feed size of the coal to the mill should be precrushed to 1" top size. Available capacity size

Reliable coal pulverizer performance is essential for sustained fullload operation of today''s power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW.. BW''s pulverizers, found at power stations throughout the world.

A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
