Pulverizer mills are mechanical devices that grind various types of materials, processing them in batches or through continuous acceptance on a conveyor. Commonly known as hammer mills, they rotate and press the bulk materials into desired states ranging from very fine to coarse depending on the degree of size reduction required.

Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types- attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.

This type of hammer mill contains a rectangular steel chamber with swinging hammers that are mounted on a shaft. The shaft rotates at a high speed and the hammering aids in particle size reduction. Additionally, particle-on-particle contact can also cause size reduction or contact in the grinding chamber with the breaker plate. The discharge ...

The work is based on tests of pulverisers of a 650 t/h pulverized fuel boiler (OP 650) in a Polish power plant. On the basis of these studies, relationships were derived between the fineness of the produced pulverized fuel and operating parameters, the efficiency of the boiler and parameters of the milling system, e.g., energy consumption of the mill and its fan.

Introduction. The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a pre-determined size in order to increase the surface area of the coal.. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.
