DIFFERENT TYPES OF SCREENS USED FOR MINING Hawk

2015-7-27  Mining operations are one of the last pioneering ventures on our planet. They descend through geological strata in search of minerals and ore, leveraging modern scientific principles against hard rock and dirt. The crux of the work is located at the mine face, a rock-breaking zone where workhorse drilling and digging tools dispatch heaps of raw rock into steel-encased grizzly feeders.

Vibratory Screens McLanahan

Screening 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 ...
