In general, therefore, the required mill power is calculated using the following equation. where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill. The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill size and type can be selected.

Substations contain the specialist equipment that allows the voltage of electricity to be transformed (or 'switched'). The voltage is stepped up or down through pieces of equipment called transformers, which sit within a substation's site. Transformers are electrical devices that transfer electrical energy by means of a changing magnetic ...

Introduction The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a predetermined size in order to increase the surface area of the coal. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.

water or steam in the steam boiler receive heat by convection from the heating surface. When any fluid in a steam boiler is heated, its density is decreases and fluid become lighter. Then the heavier or cooler fluid will flow and replace the heated portion of the fluid. In turn the cooler portion become heated are example of convection.

Wilton 10 Power Station has become the UK's first large scale biomass power station to use wood as its renewable fuel source. The £60m plant is generating 30MW of 'green' electricity the equivalent needed to power around 30,000 homes (compared to a new 42MW gas turbine, which typically costs more than £20m) and 10MW of thermal energy.

Through cables, power is transferred from the generator to a nearby transformer. Stepup transformer: While moving through wires, electricity loses part of its power; highvoltage electricity does so at a lower rate than lowvoltage energy. As a result, the voltage of the electricity is "stepped up" or "boosted" as it exits the power plant.
