โถ๏ธIntroduction
Vertical grinding mills are commonly used in the power generation, steel and cement industries. The power generation and steel industries use vertical mills for coal pulverization. There are other coal pulverizers available, but the vertical grinding mill has found widespread application due to its simple design and high efficiency.
Vertical Grinding Mill Components
Electric Motor
Grinding Rollers
Grinding Table
Gearbox
Classifier
Rockers
How Coal Pulverizers Work
Coal enters the mill and is fed to the grinding table. The grinding table rotates which throws the coal outwards towards the outer periphery of the table. The coal is then ground between stationary grinding rollers and the grinding table.
Some pulverized coal exits over the dam ring and is conveyed upwards pneumatically by the hot gas stream which enters at the base of the mill. Oversized coal is returned to the grinding table by a rotating classifier whilst correctly sized coal continues through the classifier and exits the mill through the discharge duct.
Coal Pulverizer Purpose
A coal pulverizer is designed to classify, dry and grind coal. It is beneficial to dry, grind and classify the coal prior to it entering the furnace as this gives much more efficient ignition and combustion. Coal pulverizers are a common site at many coal fired thermal power stations.
