Vertical Coal Mill, also known as coal mill, for superfine grinding of raw coal, soft coal specifically for cement, power plant, steel mill and other fields
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
How Vertical Grinding Mills Work The below video is an extract from our Mechanical and Electrical Engineering Explained Online Video Course. Raw coal (sometimes pre-treated) is fed into the centre of the grinding table. The grinding table rotates which causes the coal to move towards the outer periphery of the grinding table

Feb 05, 2021 01 Cause Analysis and Judgment Treatment. During the operation of the vertical mill, the motor drives the grinding disc to rotate through the main reducer, which drives the rotation of the grinding disc to rotate the three grinding rollers (120 uniform distribution), and the raw coal falls into the center of the grinding disc through the feeding pipe for grinding and
Aug 09, 2014 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
To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel
