mill input coal size effect importance. In addition there is heated combustion air fed to the mill to transport the pulverised coal, and the secondary air supply as shown in fig grinding the grinding function reduces coal fed into the mill into a dust with particles of the size required for combustion there are two main types of mill in common use the spindle type and the drum
Conclusions. (1) The experiments indicated that Shi–Kojovic model fits the coal breakage process in Hardgrove mill well, with a mean R2 of 0.967. (2) The form of Shi–Kojovic model can be used to simulate the relationship between t−75 and k ( Ecs − Emin) in the case of identical feed size, with a mean R2 of 0.952.

Mixtures of coal and carbonized pine chips with three different degrees of carbonization were prepared and ground using a Hardgrove grindability index mill. In the pulverized mixtures of low carbonized biomass and coal, the biomass content at all particle size ranges was nearly the same as that of the input feedstock. As the
The relation of sample size reduction degree to specific comminution energy (Ecs) was studied with Shi–Kojovic model. The results show that Shi–Kojovic model predicted well the coal size reduction degree with Ecs in Hardgrove mill. The grindability index given by Shi–Kojovic model has a …
· Coal to be used as fuel in the reheating furnace need pulverizing which can be done in different types of pulverizing mills. Pulverizing of coal needs energy (electrical energy). The amount of energy required is dependent upon (i) size of input coal, (ii) fineness od the pulverized coal, (iii) type of pulverizing mill, and (iv) Hardgrove .

The Hardgrove 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 indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill.
The base capacity is a function of grindability; fineness requirement may vary depending on the volatile matter (VM) content of the coal and the input coal size. The quantity and the inlet temperature of primary air (PA) limit the drying capacity. The base airflow requirement will change depending on the quality of raw coal and output requirement.
