Dec 13, 2011· A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills.
The mill model is running in parallel with the power plant coal mill operation; the measured and predicted outputs are displayed on the computer screens in the power plant control room. When the measured and predicted mill outputs are over the pre-set threshold values, the system will raise alarm reports to give warning signals.

A 2010 report from the Clean Air Task Force, The Toll From Coal found that, in the United States, particle pollution from existing coal power plants is expected to cause some 13,200 premature deaths in 2010, as well as 9,700 additional hospitalizations and 20,000 heart attacks.
Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.
High Ash Coals – A challenge to Power Plants – Optimisation of combustion in high ash coal fired boilers is of special interest due to the organic and inorganic mix up and the large amount of variation in the organics. One such experience with Indian low reactive coal in a tangential fired steam generator of 670 T/hr capacity is given here.
The Problem - Coal fired power plants typically operate several ball mills or coal pulverizing mills to crush the incoming coal to the optimum size for combustion. This means that each power generation unit has five or six mills. The gearboxes that run these coal mills are usually lubricated with high viscosity oil, such as ISO VG320 or ISO VG460.
