The mill reject loss depends on the amount of pyrite in coal and the mill operating condition. The rejects by the mill do have a heat value which is accounted as mill reject loss. This can be minimized by properly maintaining the mill cleanaces and operating at the optimal condition.
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 pre-crushed to 1" top size. Available capacity size
