Coal Inlet - coal is fed to the centre of the grinding table. Coal fed to the mill may be raw or pre-treated. Pulverized Coal Outlet/Discharge - pulverized coal flows out of an outlet duct. How Vertical Grinding Mills Work. The below video is an extract from our Mechanical and Electrical Engineering Explained Online Video Course.

Coal Vertical Roller Mill (VRM) is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grinding roller onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness.

Coal Vertical Mill.

Vertical rolling mill has two pairs of grinding rollers. Each pair of roller is composed of two narrow rollers and mounted on the same axis and can rotate at different speeds. The motor driving reducer make grinding plate to rotate. Raw material is sent to the center of the rotating grinding plate by the locking air feeding equipment.

The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed decreases with mill size and remains constant for a given mill diameter.

Coal vertical mills are designed to achieve the maximum rated capacity grinding a design coal with a grindability of 55 HGI and 8-12 percent moisture and achieving a discharge fineness of 70 per cent passing a 200 mesh screen (74 micron) and 99.5 per cent passing a 50 mesh screen. Variation of the coal hardness and/or moisture content will effect, up or down, the discharge …

Vertical Coal Mill for Coal Grinding in Cement Plant. Vertical Coal Mill. Feeding size: ≤110mm. Capacity: 5-70t/h. Motor power: 110-1400kW. Applications: Vertical coal mill is mainly used for grinding raw coal, bituminous coal, and other fuels into coal powder, which is supplied to rotary kiln and other kilns in the cement plant and thermal power plant.

The hot air in the coal mill will lift the coal particles out of the Raymond mill or vertical mill and into the boiler, if the coal particles are also heavy they will drop to the bottom of the coal mill too and will be grind, pulverize once again. The coal flow into the boiler is an crucial element for a coal fired power plant.
