14-12-2017· Coal Pulverizer Types (Impact, Crush and Attrition) The type of pulverizer employed depends upon requirements. Pulverizers typically utilise three main types of grinding: Impact an external force impacts with the coal. This type of grinding can be compared to when a hammer hits an object e.g. a piece of coal.

01-02-2013· Coal pulveriser design. In general, coal pulverisers are designed to achieve the maximum rated capacity grinding a design coal with a grindability of 55 HGI and 8-12 per cent moisture and achieving a discharge fineness of 70 per cent passing a 200 mesh screen (74 micron) and 99.5 per cent passing a 50 mesh screen. Variation of the coal hardness ...
The impact test was used as a quick method for quantifying such responses. Details of the heat treatments applied are also provided later. 4. Results and discussions 4.1. Visual examination of failed surfaces The fracture surfaces obtained from the failed coal pulverizer mill shafts, given in Figs. 2 and 3, have been described earlier.

Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.
4.1.1 Effect of Coal Pulverizer Outlet Temperature to Pulverized Coal Gas Flow Center Temperature It can be seen from Fig. 2 that, as the outlet temperature of the coal pulverizer increases, the temperature of the pulverized coal gas flow center at a distance of 0.4 m, 0.5 m and 0.6 m from the nozzle shows a significant increase.
• Numerous controllable variables affect the distribution of air and fuel between a pulverizer's separate fuel lines. These variables are as follows: • Size of coal particles leaving the pulverizer (Fineness). • System resistance of each individual fuel conduit. • Total airflow through the pulverizer that is controlled
pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding.
Improving Coal Pulverizer Performance and Reliability 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 Impact Mills Grinding Action is carried out by aseries of hinged or fixed hammers revolving in an Improving Coal Pulverizer Performance and Reliability Coal Conveyer Coal Crusher Raw Coal ...
01-09-2009· A dimensional sketch of a typical pulverizer is presented in Fig. 1(a).A schematic diagram showing the air and particle streams in a pulverizer are presented in Fig. 1(b). The raw coal from the coal feed chute (8) mixes with returned oversize material (7) to form a mixed stream that passes between the grinding balls and bottom grinding ring in grinder section.
17-11-2012· 2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner panels.
Impact of Pulverizer Performance on Ash Higher than desired flyash or bottom ash Loss on Ignition (LOI) or unburned Carbon content is frequently caused by less than optimum coal fineness. The graph below illustrates a typical relationship between flyash LOI and coal fineness on a tangentially fired boiler firing Eastern Bituminous coal.
• Minimal coal spillage • No rumbling • Recommended fineness •<0.1% retained on 50 mesh •>75% passing 200 mesh • Bright and attached burner flames • Low LOI (Direct impact of pulverizer performance) • Balanced airflow in fuel lines • Balanced fuel flow to burners Fuel Fineness testing is a measure of performance
