The average coal unit in Romania is today 42 years old, their age varying between 32 and 52 years. This means that the average age will reach 53 years in 2030, way past the estimated economic viability of coal power plants, which is approximately 40 years. Retiring such a small number of units during
More DetailsScreening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification. Material must go through or over a specified size to end up in the ...
