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.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
Pulverized Coal Mill Operation Principle. Coal feed systems for boiler and coal milling plant gravimetric coal feeder 1957 designated as asme historic landmark in 1995. feed or power combustion in pulverized coal
#0183;#32; 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.

Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.

#0183;#32;Coal mill hot air inlet temperatures should never be more than 600 #176; F and the outlet temperature should not exceed 200#176;F on Raymond coal mills. If the flow of raw coal to the coal mill is interrupted for any reason (for example: plugging, failure of the coal feeder, etc.), the outlet temperature of the coal mill can quickly climb to dangerous levels.
Reliable coal pulverizer performance is essential for sustained fullload operation of today''s power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW.. Bamp;W''s pulverizers, found at power stations throughout the world.
Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill sees instantaneously unless some damping system such as a surge hopper is used.
on 70% of the coal passing through a 200 mesh screen. Mills are capable of grinding harder coal with higher percentage moisture content and can reduce the product fineness in excess of 90% passing a 200 mesh screen at a reduced output capacity. The feed size of the coal to the mill should be precrushed to 1 top size. Available capacity size
