To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.
The mills installed at the GhecoOne power plant were designed by Loesche Energy Systems Ltd and are of the type. The internal diameter of the coal feed pipes downstream to the mill is mm. The mills are equipped with dynamic classifiers of the type LSKS39. They are generally operated with a classifier speed around 80 rpm.

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 predetermined 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.
Crushers, grinding mills and pulverizers are types of grinding equipment used to transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. Grinding equipment can be classified into to two basic types, crushers and grinders. Industrial crushers are the first level of size reducer; further granularization ...
