Holmes Coal Pulverizers are benchtype units that perform well in reducing coal or coke from No. 4 to No. 60 sieve size. Models are available with manual or auger feed. All units are constructed of painted steel and cast iron and have a onepiece balanced rotor with hard coated hammers driven by 1hp singlephase motor with overload protection.

Coal Pulverizer Pall. 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 Millsget price
The raw coal is then fed into the pulverizer along with air heated to about 330 C (650 F) from the boiler. As the coal gets crushed by the rolling action the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler
A pulverizer or grinder is a mechanical device for the grinding of many different types of materialsor example a pulverizer mill is used to pulverize coal for combustion in the steamgenerating furnaces of fossil fuel power plants pulverizing the coal to a fine powder is an important function in the operation of a power plant.

Why Pulverized Coal is Used in a Power Plant. Coal normally is available to power plants in large lumps ranging from 2 mm to 50 mm size. Coal is commercially available in different sizes known as "Run of Mine " "stoker " "slack " etc. depending on their size. In the olden days coal burning was done on grates without any change in size or
A Comparison of Three Types of Coal Pulverizers. spiral bevel geardrive was the first removable coal pulverizer Pulverizers are used to reduce the size of Data taken on typical pulverizers Pulverized Coal Pipe Testing and Balancing Data taken on typical pulverizers illustrates that only Coal pipe F9 on pulverizer B was the only pipe that of Coal Pulverizers by reducing the coal to a nominal 1/
The coal pulverizer is applied to crush the coal to an average size of mm powder. At the entrance of coal pulverizer the temperature would be between 160 C to 393 C. The blowing speed is 50 to 55 m/second. When the high Cr cast steel (4858 HRC) liner plate is used the service life is to 2 years but spalling would be an issue.
