Higher pulverized coal fineness increases the recirculation in the mill and the output reduces. The inlet size of the coal also affects the mill output directly. Mill air flow variations result in changes in mill outlet temperature and fineness as well as capacity. Ball tube mill. Ball tube mills are either pressurized or
The isokinetic coal sampling method, although more difficult, is the best option for determining the true mill coal fineness produced and to calculate pulverizer performance. We perform isokinetic
Coal mill is the equipment used for grinding and drying coal with different hardness and it is mainly composed of feeding device, principal axis, rotating the part, transmission part, discharging part, highpressure starting device, and lubriion system. It is widely used cement, building material, thermal power generation, metallurgy, and chemical industry.
Instead of maximizing coal fineness improvements only, the dynamic classifiers can be used to increase mill capacity while improving the preretrofit fineness level somewhat or the capacity can be maximized by allowing the fineness to drop to lower levels.

Coal fineness is a relative measurement of particle size distribution typically applied to the product leaving a pulverizer. Standardized wire mesh screens are stacked and used to shake down samples.
Dec 13, 2011 · The Hard grove index, total moisture, input coal size, output fineness, and mill wear have direct impact on the mill output. The Hardgrove index of coal tells us about the ease with which it can be pulverized. A higher Hardgrove index indies the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill.
