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 capacity or the.
Oct 11, 2019 The two most common compressive comminution technologies are the high pressure grinding roller (HPGR) and the vertical-roller-mill (VRM). For now, the HPGR has already presented in a noteworthy number of mining projects whereas VRM technology, a new entrant, is still not fully accepted. This is considered a resistance to change considering that.

Vertical Mills comprise 2-4 conical rollers which are hydraulically pressed onto a horizontal rotating grinding table. Material is directed onto the centre of the table and is thrown outward by rotation under the rollers. Fines pass out with the air current while coarse material falls back onto the feed table.
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.
