Kiln firing system key to white cement manufacturing process. In the white cement manufacturing process, the kiln firing system is the key to the entire cement production line, which affects the product quality and energy consumption of the entire white cement plant. Therefore, it is important to rationally design the kiln firing system.
Pulverizers / Mills. 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. BW's pulverizers, found at power stations throughout the world.
The wet coal is fed into a pulverizer along with hot gases drawn from the firing hood. The hot gas temperature is controlled by bleed air. The coal or coke is simultaneously dried and ground in the hotair swept pulverizer. The pulverizer can be a hammer mill, ringroll mill, or a ball mill type.

kiln and particularly relates to a direct coal firing System using a burner with a multibarrel construction. BACKGROUND OF THE INVENTION In a direct coal firing System, hot air is drawn from a rotary kiln hood and is used to dry coal before it is Sent to a mill for pulverization. The pulverized coal is entrained in
1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
The coal is then proportionately mixed if required to get uniform desired quality. This coal is then fed into dump hopper to feed in the ball mill where it is pulverized to desired fineness at 12 13 TPH and stored in fine coal bins for PC and Kiln firing.

Since one kilogram (or pound) coal requires approximately kg (or !b) air for combustion, the fueVair mixture emanating from the coal mill must be kept well below this critical ratio to prevent premature ignition. Most coal mills operate at air/fuel ratios that are less than kg (lb) per kg (lb) of coal.
Precalcining technology. The precalcining technology is a technical leap of cement calcining process, with a series of excellent properties and characteristics such as high quality, high efficiency, and low consumption. Add a precalciner between the preheater and the rotary kiln, or use the uptake flue at kiln end, and set up a fuel injection ...
The 5stage suspension preheater cyclone is the device inside which the cement raw meal performs heat exchange with hot gas from the rotary kiln and is preheated.
