NTPC LTD CORPORATE OPERATION SERVICES, EOC, .

To support the production of cement, the plant has modern vertical roller grinding mills along with tube mills both for raw meal as well as coal. Cement grinding is achieved exclusively by tube mills/horizontal ball mills. The final products of the plant include PPC, OPC, PSG and other special cements.Basic Operation : A thermal power plant basically works on Rankine cycle. . Ball and Tube Mill . Ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.

Performance Driven Maintenance of Coal Pulverizers

three Riley Power double-ended ball tube mills. Each mill can provide 65 tons per hour of pulverised coal to the boiler, or a total of 195 tons per hour, per boiler. Because the ball-tube mills have outlets at each end, with a classifier on each outlet, two sample points were needed on each mill. For enhanced reliability, a redundant configurationthe policy all fluidised bed and pulverised coal units (coal based thermal power plants) except those having ball and tube mill, of power generation utilities, public or private, located in India, shall endeavour to use 5-10% blend of biomass pellets made, primarily,

BALL MILL GEARBOX PROBLEM - Vibration

Figure 4 compares a conventional vertical table type pulverizer with a ball tube mill pulverizing system with crusher dryer. The table type pulverizer allows high temperature air to reach the coal charge. The ball mill system with crusher dryer normally reduces the inlet temperature to less than the auto ignition point of the coal charge.The Power Generation industry harnesses energy from multiple sources including fossil fuels (coal and gas), nuclear power, biomass, waste heat and renewable natural resources. It is also under intense environmental scrutiny and regulation. All power generating systems operate rotating parts working under arduous and continuous use.
