PulverizersPulverizers TypesPulverizers TermsPulverizers are used to reduce the size of materials through grinding and crushing. Size reduction is an important part of a wide variety of industrial processes. Pulverizer manufacturers provide pulverizers that can be used on many different material types, including brick, shale, coal, concrete, limestone, wood, and even plastic materials. Because there are so many uses of pulverizers, and because they are used to process such a wide range of materials, an equally wide range of pulverizer c...

Types of Boiler Coal Pulverizers - Bright Hub Engineering

Attrition TypeImpact and Attrition TypeImpact Or Hammer TypeCoal feeds onto a steel rotating table. Tapered, cylindrical, or spherical rollers on top of the table, under spring pressure, exert force on the coal particles on the table. When the table rotates, the coal passes between the rollers and the table and gets ground due to attrition. The hot air under pressure carries this ground coal upwards. Larger particles fall back to the grinding table. These coal particles then pass through a classifier where the large particles get separated due to cent...

Pulverizer Fire and Explosions

The presence of combustible materials in the pulverizer is usually the largest contributor to pulverizer fires. In most cases, pulverizer fires begin in the under bowl area of the pulverizer that is a very hot environment with an abundance of air. Accumulations of debris or coal anywhere in the pulverizer will increase the chance of a mill fire.

Why Pulverized Coal is Used in a Power Plant - Bright Hub ...

A 2000 MW power station could be handling coal in the range of 1600 tons/hr or around 12 million tons of coal annually. A single 500 MW unit consumes in the range of 400 tons/hr of coal. The coal input to the boiler of the power plant passes through three different phases before combustion in the boiler.

Pulverised Coal - an overview ScienceDirect Topics

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.
