the pulverizer system design lies in the selection of air to coal ratios to handle the specific coal property. Figure 9 shows a typical ball tube mill arrangement including crusher dryers. Figure 10 illustrates changes in air coal ratio necessitated by different coal characteristics.
1.7 Lignite Combustion 1.7.1 General1-5 Coal is a complex combination of organic matter and inorganic ash formed over eons from successive layers of fallen vegetation. Coals are classified by rank according to their progressive alteration in the natural metamorphosis from lignite to anthracite. Coal rank depends on the volatile

The crusher was driven by a small steam engine which was mounted behind the hand brake column. The crusher reduced the coal to a suitable size for the stoker. The crushed coal then fell by gravity into a chute which led to a receiving bin, fitted below the back buffer beam of the locomotive. From here it was picked up by a bucket elevator which ...

As shown in Figure 2, coal and preheated primary air first enter the crusher section. Here the coal is im- pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4" size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the two-stage pulverizing sec- tion.
Coal mines reducing ROM to stoker coal or finer for shipment What type of tests should be considered before deciding on a Hammermill Crusher? Testing for abrasive characteristics in the material is a logical first step when considering the cost to replace hammers and liners.

STOKER COAL. The coal used in the All Canadian Coal-Fired Heater (which is also the most readily available coal in Western Canada) is called sub-bituminous (b) stoker coal. Stoker coal (characterized by egg-sized lumps of coal) comes oiled (to minimize dust), and dry (un-oiled).
The belt further elevates the coal to the transfer point 7 and it reaches the crusher through belt. In the crusher a high-speed 3-phase induction motor is used to crush the coal to a size of 50mm so as to be suitable for milling system. Coal rises from crusher house and reaches the dead storage by passing through transfer point 8.
Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal,crushing and pulverizing it.
