An unprecedented growth is being witnessed by the power sector with a capacity addition of over 78,000 MW envisaged during 11th Plan and about 80,000 MW in 12th Plan. A programme of this magnitude requires that every possible opportunity for enhancing pace .
PULVERIZING PLANT / COAL MILL: In modern thermal power generation plants in order to achieve maximum burning efficiency coal is pulverized or ground in order to mix it with the hot air and then feeding to furnace in a stream of hot air. This helps increasing the surface area of the coal to action of oxygen and consequently helping combustion.
Powder Technology, 49 (1987) 191 192 Grinding Behaviour of Coal in Different SizeReduction Systems S. F. SCIESZKA* Energy Research Institute, University of Cape Town, Private Bag, Rondebosch 7700 (South Africa) (Received January 24, 1986) 191 SUMMARY It was found that it is easer to grind some coals in ballrace mills and others in tube mills.
Pulverisation of coal by attrition and by impact of hard balls Speed reduction achieved by gear train consisting of reduction gear box and large spur gear. Coal can be fed and removed from both sides of the mill. Half mill operation for partial loads allowed. Input coal size 25 mm white output is 70 to 90 microns

Pulverized form of coal has made modern steam generating units highly thermal efficient, reliable, safe and able to efficiently use of lowgrade coals. It provides coalair fuel control, flame stability, effective utilization of carbon and thus reduction in cost and flexibility of operation.
A. Modelling Study of Tube Ball Mills 1. Initial Model of the TubeBall Mill The mathematical model of the TubeBall mill was developed based on fluid mechanics; principles electrical engineering, thermodynamics and aerodynamics Wt K A t K A t cfP fP ()=⋅ + ⋅ 11 2 2 (1) As the total mass of coal fed into the mill per hour is given in
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 twothirds of the ball mills.
In coal crusher coal size reduced up to ¾" after that coal transfer to the boiler's coal bunker or coal yard. In the case of emergency the coal is fetch from coal yard. Coal feeder control the quantity of coal from coal bunker and send it to the ball mill or roll mill for pulverization process. Where coal .
All Coal Mill First Principles Programs Include the Following: Perform mill internal inspections, looking for wear, erosion, corrosion, inappropriate modifications, missing or broken parts, or nonfunctioning parts. Inspection includes classifier outlet cylinder vs classifier vane height, classifier roof and cone, classifier blades, and outlet restrictions.
The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill, have significant effects on the mill capacity and the milling efficiency. Small balls are effective in grinding fine particles in the load, whereas large balls are required to deal with large particles of coal or stone contaminant.
