#0183;#32;It is an important parameter in blast design and has a vital influence on the resultant fragmentation. Higher powder factor causes oversize and lower powder factor results in crushed rock. Mean fragment size was plotted against the powder factor for 91 blasts of coal overlying overburden benches, as presented in Fig. 22.
The most common process is the use of a blast furnace to produce pig iron which is about 9294% iron and 35% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon content and adding other elements such as manganese and nickel to give the steel
When one roller expands tubes into grooved holes, tube metal extrudes into the grooves. But mechanical rolling may cause tubeend fatigue, depending upon the frequency and amplitude of the stresses the rollers apply. The frequency is far more effective in producing fatigue than the amplitude.
The blast cleaning process is controlled by the method of material handling. The parts are conveyed at a constant angle of 90 degrees to the blast wheels, while the rotation of the pipe or tube in front of the blast wheels ensures all surfaces are cleaned evenly.

The four most common types of coal pulverizers are: BallTube Mills This type of mill consists of a rotating tube filled with cast alloy balls. 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
When the coal is removed from the mills through a blast of hot air, if the coal is too wet, the drying out is ineffective and has a negative effect on the combustion of coal.
To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
Causes Of Blast In Tube And Ball Coal Mill Control of Pollution in the Iron and Steel Industry The iron and steel industry causes significant effects on environmental media air, water and soil. iron ore, coke breeze, limestone, mill scale, and flue dust into an agglomerated product (sinter) at suitable size for charging into the blast furnace.

#0183;#32;The coal pulverizers are the heart of a pulverized coalfueled boiler. About 75% of the opportunities for improvements in tuning are with the coal mills, primary airflow, and fuel line balancing.
The Surface Mining Control and Reclamation Act of 1977 (SMCRA) requires that coal mining be conducted in a manner that prevents injury to people and damage to public or private property during blasting. The side effects of blasting are flyrock a rock or rocks moving through the air or along the ground after a blast and travel beyond the blast area (security zone),
Blast nozzle spray patterns are affected by orice size, air pressure, and distance from the workpiece. The total diameter of the blast pattern increases as the distance from the workpiece is increased. The hot spot (where work speed is maximized) can be obtained at larger distances from the workpiece with pressure air blast systems.

Fig 1 Pulverized coal combustion and gas composition in raceway. The extent of combustion (combustion efficiency), and hence the amount of unburnt material transported out of the raceway, depends on several parameters which include (i) properties of the coal, such as the VM content, particle size and density, and (ii) operating conditions, for example, blast gas composition and temperature
